Koh Lanta

Discovering Koh Lanta

I came to Koh Lanta after a week of island-hopping — Phuket’s traffic, Krabi’s tour boats, Koh Phi Phi’s party crowds — and Lanta felt like someone had turned the volume down. The ferry from Krabi docked at Saladan pier, and within ten minutes I was on a scooter heading south on the island’s single main road, passing beach turnoffs with hand-painted signs and roadside restaurants where the cook was also the owner, the waiter, and the dishwasher. No touts. No neon. No one trying to sell me anything. Just the road, the jungle, and the distant sound of waves through the trees.

Koh Lanta is not undiscovered — Scandinavian and German tourists have known about it for decades — but it has resisted the development pressure that transformed Phuket and Samui. There are no high-rises, no jet skis, no walking streets packed with vendors. Instead, a single road runs the length of the island past a string of beaches, each one slightly quieter than the last, ending at Mu Koh Lanta National Park where a lighthouse overlooks the Andaman Sea. The island is 30 km long and feels like five different destinations depending on where you stop: family resort in the north, bohemian beach bar in the middle, near-wilderness in the south.

What makes Koh Lanta unusual among Thai islands is its composition. It is a family island, a couple’s retreat, a budget traveler’s haven, and a diving base — simultaneously — without any of those identities overwhelming the others. The party backpackers go to Phi Phi. The luxury seekers go to Samui. The Instagram crowd goes to Railay. Lanta gets the people who want a beach, a book, a cold beer at sunset, and nothing else on the agenda. That selectivity has shaped the island’s character more than any development plan ever could.

Old Town on the east coast sealed the deal for me. Wooden shophouses on stilts over the water, cats sleeping on porches, a single-road village where Chinese, Malay, and sea gypsy cultures have blended for centuries. I had grilled fish for lunch at a table overlooking the mangroves and knew I would come back. Old Town (Ban Si Raya) is the island’s soul — the part that existed long before tourists arrived and will remain long after travel trends shift. The Sunday walking market, with local food stalls and handmade jewelry, is one of the most genuine markets I have found in southern Thailand.

What Makes Koh Lanta Different?

Koh Lanta’s appeal is what it does not have: no airport, no major nightlife, no all-inclusive mega-resorts, no full moon parties, no parasailing operations, no jet ski rental stands. What it does have is 25 km of west coast beaches ranging from developed (Klong Dao, Long Beach) to nearly deserted (Bamboo Bay, Nui Bay). The absence of an airport is the key. Every visitor arrives by boat or car ferry, which imposes a natural filter — you have to want to be here, and that wanting shapes the entire atmosphere. The people who make the effort to reach Koh Lanta tend to be the kind of travelers who leave a place better than they found it.

Mu Koh Lanta National Park at the southern tip (200 THB / $5.70 entry) has a lighthouse, rocky beach, and short jungle trail through old-growth forest where monitor lizards sun themselves on rocks and hornbills call from the canopy. The park is small — you can see everything in two hours — but the lighthouse viewpoint at sunset is one of the Andaman coast’s finest. The lighthouse itself is painted white and perched on a headland that drops straight to the sea on three sides. I watched the sun set from the bench beside it and counted seven islands on the horizon, each one catching the last light at a slightly different angle. Nobody else was there. That does not happen on Phuket.

The island also functions as the primary staging point for Koh Rok, a pair of uninhabited national park islands 30 km south with some of the clearest water in Thailand — 15 to 25 meters of visibility on good days, pristine coral gardens, manta ray sightings from November to April, and white sand beaches that look computer-generated but are emphatically real. For serious snorkelers, Koh Lanta’s value is not its own shores but its proximity to Koh Rok, Koh Haa, and the dive sites at Hin Daeng and Hin Muang. Check our snorkeling guide for current visibility reports and seasonal recommendations across the Andaman coast.

What Are Koh Lanta’s Best Beaches?

The beaches run north to south along the west coast, and there is a simple rule: the further south you go, the quieter it gets. Each beach has a distinct character, and choosing the right one is really about choosing what kind of day you want.

Klong Dao Beach is the northernmost and most family-friendly. The sand is wide and clean, the water is shallow and gentle for 50 meters out, and the beach is backed by mid-range resorts and casual restaurants. This is where families with small children base themselves, and for good reason — the swimming is safe, the food is close, and the atmosphere is relaxed without being deserted. Sunset here is excellent, with unobstructed views across the Andaman.

Long Beach (Phra Ae) is Koh Lanta’s main event — a 4 km stretch of golden sand lined with beach bars, restaurants, massage huts, and guesthouses of every price range. Long Beach has the island’s best restaurant concentration and enough nightlife to satisfy without the full-moon-party chaos. I spent three evenings here and never ate at the same place twice. The southern end of Long Beach is quieter and often nearly empty, even in high season. If Koh Lanta has a social center, this is it.

Kantiang Bay is a secluded crescent about 20 minutes south of Long Beach by scooter, framed by jungle-covered headlands on both sides. The water is deeper and clearer than the northern beaches, the sand is softer, and the overall vibe is honeymooners and couples reading novels. Pimalai Resort occupies the hillside above the southern end, but the beach is public and accessible. The handful of restaurants here are small, owner-operated, and serve some of the best seafood on the island — the kind where you point at the fish in the cooler and they grill it for you.

Bamboo Beach (Ao Mai Pai) and Nui Bay are the wild cards. Bamboo Beach, near the national park, is a wide stretch of sand backed by bamboo forest with minimal development — a few bungalow operations and a shack or two selling drinks. Nui Bay requires a short hike or a scramble down a rocky path, and the reward is a small cove that feels entirely private. These are the beaches for people who want to disappear for an afternoon. Bring water and snacks — there is nothing to buy.

What to Do on Koh Lanta

Koh Lanta is not an activity island in the way that Krabi or Phuket demand constant itinerary management. The pace here encourages doing less, doing it slowly, and paying attention. That said, there are genuine highlights worth planning around.

Four Islands Snorkeling Tour — Koh Lanta’s signature day trip visits four islands in the Trang archipelago: Koh Chuek (small coral reef), Koh Mook (the Emerald Cave), Koh Ngai (white sand beach lunch stop), and Koh Kradan (clear water snorkeling). The Emerald Cave on Koh Mook is the showpiece — you swim through a dark sea cave for 80 meters, using a waterproof headlamp or your guide’s flashlight, and emerge into a hidden lagoon surrounded by 100-meter limestone walls open to the sky. It is one of the most dramatic natural experiences in Thailand. Tours run 1,500-2,500 THB ($43-70) per person with lunch, snorkeling gear, and national park fees included. November to April only. Book through your hotel or a Saladan travel agency.

Mu Koh Lanta National Park — At the southern tip of the island, the national park (200 THB / $5.70 entry) offers a short nature trail through old-growth forest, a rocky beach where white-bellied sea eagles hunt, and the lighthouse viewpoint. The trail takes about 45 minutes and passes through dense jungle where you might spot monitor lizards, langur monkeys, and dozens of bird species. The lighthouse itself is the island’s most photographed spot — white against the blue sea, with views stretching to Koh Rok on clear days. Go in the late afternoon for sunset. There is a small cafe selling drinks and snacks near the parking area.

Sea Kayaking in the Mangroves — The east coast of Koh Lanta is fringed with mangrove forest, and guided kayak trips explore the channels between Lanta Noi and Lanta Yai (the two halves of the island, connected by a bridge). Half-day tours run 800-1,200 THB ($23-34) and paddle through root tunnels where crabs, mudskippers, and kingfishers are your only company. The silence in the mangroves — interrupted only by the dip of your paddle — is a sharp contrast to the tourist beaches on the west coast. Several operators launch from the Saladan pier area.

Old Town (Ban Si Raya) — More of an experience than an activity, but worth a deliberate visit rather than a drive-through. The east coast village of stilted wooden shophouses was built by Chinese and Malay traders generations before tourism arrived. Today it has a handful of cafes (Hammock House is the best for coffee), art galleries displaying work by local and expat artists, a small community museum, and waterfront restaurants where the seafood was swimming that morning. The Sunday walking market (3-7 PM) has local food stalls, handmade soap, woven textiles, and jewelry. Arrive by 4 PM for the best selection. Entry is free. Dress modestly — Old Town has a significant Muslim community.

Cooking Class at Time for Lime — Junie’s cooking school at Klong Dao is the island’s best. The half-day class (2,500 THB / $70) starts with a guided tour of the local market where you learn to identify Thai herbs and choose produce, then moves to an open-air kitchen overlooking the beach where you cook five dishes — typically a curry paste from scratch, a stir-fry, a soup, a salad, and a dessert. The southern curry paste lesson alone changed how I cook at home. You eat everything you make for dinner. Classes run Monday through Saturday; book a day ahead in high season. For more on southern Thai cooking and the flavors of the Andaman coast, see our cuisine guide.

Diving at Koh Haa and Hin Daeng — Koh Lanta is one of southern Thailand’s best dive bases, with easy access to Koh Haa (a cluster of five islands with swim-throughs, caverns, and soft coral gardens), Hin Daeng and Hin Muang (submerged pinnacles where whale sharks and manta rays are regular visitors from November to April), and Koh Rok. Two-dive day trips start at 3,500 THB ($100) for Koh Haa and 4,500 THB ($128) for Hin Daeng. Lanta Diver and Scubafish are the most established operators, both PADI-certified with multilingual instructors. Open Water certification courses run 13,000-16,000 THB ($370-455) over 3-4 days.

Koh Rok Day Trip — If you do one excursion from Koh Lanta, this is the one. Koh Rok Nai and Koh Rok Nok are twin national park islands 30 km south with visibility that regularly exceeds 15 meters, pristine hard and soft coral, resident giant clams, and beaches so white and empty they look staged. Manta ray sightings are common from December to March. Day trips run 1,500-2,500 THB ($43-70) including lunch, snorkeling gear, and national park fee. The islands are only accessible November to April when the national park is open. Overnight camping is available with a permit (book through the DNP website or a Lanta tour agency).

Where to Eat on Koh Lanta

Koh Lanta’s food scene is unpretentious and genuinely good. The southern Thai Muslim cooking influences are strong — turmeric-heavy curries, biryani rice, and roti served with curry sauce rather than the sweet condensed milk version you find up north. The seafood is exceptional and cheap, pulled from the Andaman that morning. Most restaurants are small, family-run operations where the quality depends on who is in the kitchen that day. Here are the ones I kept returning to.

• Time for Lime — Cooking school and restaurant at Klong Dao beach. The kitchen turns out excellent southern Thai seafood — the massaman curry with prawns (220 THB / $6.25) is rich and complex, and the grilled whole sea bass with lime and chili (280 THB / $8) is the best I had on the island. The terrace overlooks the beach and the sunset views are unobstructed. Cooking classes 2,500 THB ($70) including market tour. Open daily for dinner; closed Wednesdays in low season.

• Drunken Sailors — Long Beach coffee shop and brunch spot that has become the island’s social hub by default. Good espresso (70 THB / $2), eggs and toast (120 THB / $3.40), Thai iced coffee (60 THB / $1.70), and a blackboard menu of sandwiches and salads that changes daily. The vibe is barefoot-and-laptop — digital nomads in the morning, beach-hair couples in the afternoon. Opens at 7:30 AM, which is early by Koh Lanta standards.

• Red Snapper — A beachfront restaurant at Long Beach with its feet in the sand. The menu is Thai-international, but stick to the Thai side — the yellow curry with crab (250 THB / $7) is outstanding, and the pad Thai with prawns (150 THB / $4.25) is cooked in a wok over high heat, which makes all the difference. Fresh fruit shakes 70 THB ($2). Good cocktails at sunset. Slightly more expensive than the inland restaurants, but you are paying for the ocean view and bare feet in the sand.

• Same Same But Different — A Long Beach bar-restaurant with live music some evenings and a Thai-Western menu. The tom yum soup with seafood (180 THB / $5) is spicy and fragrant in the southern style, and the green curry with chicken (140 THB / $4) is properly hot. The barbecue nights (Saturday, mixed seafood grill for 350 THB / $10) draw a crowd. Beer Lao on draft. The name is a cliche but the food is not.

• Old Town Seafood Restaurants — The waterfront restaurants along Ban Si Raya’s single road do not need individual names because they all do the same thing well: fresh seafood, cooked simply, served on a terrace over the mangroves. Steamed sea bass with lime and garlic (200 THB / $5.70), stir-fried morning glory (60 THB / $1.70), pad Thai (60 THB / $1.70), and cold Singha. Walk the strip, look at what other people are eating, and sit down at whichever place looks busiest. Budget 200-400 THB ($5.70-11) per person.

• Kwan’s Cookery — A small, locals-and-expats place on the road between Long Beach and Kantiang Bay, easy to miss but worth finding. Kwan cooks southern Thai comfort food: khao mok gai (chicken biryani with turmeric rice, 70 THB / $2), massaman curry (100 THB / $2.85), and her signature deep-fried fish cakes with sweet chili sauce (80 THB / $2.25). No English menu — she will tell you what is good today and she will be right. Cash only. Closed Sundays.

Where to Stay on Koh Lanta

Accommodation on Koh Lanta spans the full range from 400 THB bamboo huts to 12,000 THB hillside villas, and the quality-to-price ratio is consistently better than on Phuket or Samui. The island has no chain hotels, which means every property has personality — for better or worse. Location matters: Klong Dao and Long Beach are the most convenient for restaurants and activities, Kantiang Bay is the most beautiful and secluded, and the far south is for people who want genuine isolation.

• Lanta Manda — Cheerful budget bungalows tucked behind Long Beach with hammocks strung between palm trees, a shared kitchen, and owners who remember your name by the second morning. The fan bungalows (500-800 THB / $14-23 per night) are basic — concrete floor, mosquito net, cold water — but clean and just 100 meters from the beach. Air-con rooms available for slightly more. Best for backpackers, solo travelers, and anyone who spends their budget on experiences rather than thread count.

• Lanta Casa Blanca — A boutique guesthouse at the quiet end of Long Beach, run by a Thai-Swedish couple who have refined the formula over a decade. The rooms are simple but stylish — white walls, wood floors, good mattresses, modern bathrooms. The small pool is surrounded by frangipani trees and the on-site restaurant does an excellent breakfast. 1,200-2,500 THB ($34-71) per night. The sweet spot between backpacker budget and resort spending. Best for couples.

• Layana Resort & Spa — An adults-only boutique resort on Long Beach that manages to feel exclusive without being pretentious. The beachfront pool is long and uncrowded, the rooms are spacious with balconies facing the sea, and the spa uses local herbs and techniques. The restaurant, Tides, is one of the best on the island. 5,000-10,000 THB ($142-285) per night. No children under 18 — this is deliberate and part of the appeal. Best for couples seeking quiet luxury.

• Pimalai Resort & Spa — Koh Lanta’s flagship property, built into the hillside above Kantiang Bay with three pools cascading down to a private beach. The rooms open to jungle canopy, the breakfast buffet is the island’s best, and the setting — surrounded by forest with the bay below — is spectacular. 4,000-8,000 THB ($113-225) per night for the standard rooms; villas go higher. The resort runs its own longtail boat for beach transfers. Best for families and couples who want the finest property on the island without the corporate resort atmosphere.

• Crown Lanta Resort & Spa — Beachfront villas in the island’s quiet south, near the national park road. Each villa has a private terrace, and the property’s isolation means you hear waves and birdsong, not traffic. The pool overlooks a rocky stretch of coastline that attracts white-bellied sea eagles in the early morning. 6,000-12,000 THB ($170-340) per night. The location is remote — you will need a scooter to reach restaurants and shops — but that remoteness is the point. Best for travelers who want seclusion.

The Lighthouse at the Edge of the Island

There is a point on Koh Lanta where the road simply ends. Past the last resort, past the last beach bar, past the national park entrance gate, the path narrows and the jungle presses in from both sides. Then the trees open and you are standing at a white lighthouse on a headland that drops vertically to the sea.

The Mu Koh Lanta lighthouse is not architecturally remarkable. It is small, recently painted, functional. But its position — on a spit of rock at the southernmost tip of the island, with open water in every direction — gives it the quality of an ending. To the west, the Andaman stretches unbroken to the horizon. To the south, on clear days, you can see the dark shapes of Koh Rok and Koh Ngai. Below, the rocks are black and sharp and the water churns even on calm days. The wind is always stronger here than on the beaches.

I sat on the bench beside the lighthouse one evening as the light changed from white to gold to the deep amber that the Andaman coast produces for about twelve minutes between sun and darkness. A pair of white-bellied sea eagles circled the headland, riding the thermals without a single wingbeat. The rocks below turned rose-colored, then violet. The lighthouse lamp flickered on. Behind me, the jungle was already dark and full of the sounds that begin when the daytime birds stop — cicadas, geckos, something larger moving through the undergrowth.

It was the kind of moment that does not photograph well but stays in memory with perfect clarity. The lighthouse is not a tourist attraction in any conventional sense. There is no show, no entry fee beyond the national park ticket, no guide explaining what you are seeing. It is simply a place where the island runs out and the ocean begins, and if you time it right, the transition between day and night happens in a way that reminds you why you travel.

Where Can You Go from Koh Lanta?

Koh Lanta’s position in the southern Andaman makes it a natural waypoint on the island-hopping trail between Krabi and the deep south.

Koh Rok (1.5 hours by speedboat, day trip 1,500-2,500 THB / $43-70) — Twin national park islands with the clearest water I have snorkeled in Thailand. Pristine coral, giant clams, and manta ray encounters from December to March. White sand beaches that you might have to yourself on a weekday. Overnight camping is available with advance permit. Open November to April only. For snorkeling conditions and gear recommendations, check our snorkeling guide.

Koh Phi Phi (1 hour by ferry, 400 THB / $11) — The famous backpacker island with Maya Bay, the Pileh Lagoon, and a nightlife scene concentrated on a narrow isthmus between two bays. Day trips work if you only want the scenery; an overnight reveals the bioluminescent plankton and the viewpoint sunrise. Koh Phi Phi is everything Koh Lanta is not — loud, crowded, and intense — which makes it an interesting contrast if you have the time.

Krabi (1.5 hours by ferry, 350-400 THB / $10-11) — Railay Beach, Tiger Cave Temple, and the limestone karst coastline. Krabi is the natural companion to Koh Lanta and most travelers visit both. The ferry from Lanta docks at Krabi’s Klong Jilad Pier, from which longtail boats to Railay and Ao Nang depart regularly. See our full Krabi guide for the complete itinerary.

Koh Lipe (3-4 hours by speedboat in season, 1,800-2,500 THB / $51-71) — Thailand’s southernmost resort island, near the Malaysian border, with crystal water and some of the country’s best reef snorkeling. The Tigerline and Satun Pakbara speedboats connect Lanta to Lipe during high season (November to April). This is a long and sometimes rough crossing — sit outside if you get seasick.

When Koh Lanta Stays With You

I have been to louder islands and more famous ones. I have swum in clearer water at Koh Rok and eaten better single meals in Bangkok. But Koh Lanta is the place I think about when someone asks me where they should go in Thailand if they want to feel like they are actually on vacation — not performing vacation, not curating vacation, not rushing between attractions with a checklist. Vacation as a state of being: slow mornings, warm water, a scooter with a full tank, and nowhere in particular to be.

My last morning on Koh Lanta I rode south to the national park at sunrise. The road was empty except for a few dogs trotting along the shoulder and a woman sweeping the porch of a bungalow that may or may not have been open for business. At the lighthouse, the sea was flat and silver and the horizon was a thin pink line. I stood there for twenty minutes and did not take a photograph. Some places earn their reputation through spectacle. Koh Lanta earns it through the quiet accumulation of moments like that one — unremarkable in description, irreplaceable in memory.
