TL;DR: Koh Lanta’s best things to do split into beaches, one national park, one old town, and a handful of boat day trips. The west-coast beach run (Long Beach/Phra Ae, Klong Nin, Kantiang Bay, Bamboo Bay) is free to walk, with sunbeds and restaurants at every stop. Mu Ko Lanta National Park, at the island’s southern tip, costs around ฿200 (about US$6) for foreign adults and covers the Laem Tanod lighthouse trail and Khlong Chak waterfall, open roughly 8am-5pm. Lanta Old Town, the Chinese-Thai stilt-house fishing village on the east coast, is free to wander. Snorkelling day trips to Koh Rok and Koh Haa run about ฿1,700-2,100 (US$52-64) including lunch, plus a ฿400 park fee; the Emerald Cave 4-island trip to Koh Mook runs around ฿1,500-1,900 (US$45-58). Mangrove kayaking at Thung Yee Peng costs roughly ฿1,300-1,800 (US$39-54) for a half day. Nightlife is low-key beach bars, not clubs, and the island has a real digital-nomad scene built around KoHub coworking space. All prices in THB with USD in parentheses at ฿33 = US$1 (July 2026); most figures are ranges since operators and seasons vary.
Koh Lanta is the Andaman island recommended by people who already did Phuket and Phi Phi and wanted something slower. It’s a long, low island in Krabi province with no real town centre, just west-coast beaches, a national park at the southern tip, an old Chinese-Thai fishing village on the quieter east side, and a scattering of coworking cafés that made it a fixture on the digital-nomad map. This guide covers the beach run, the national park and lighthouse, Lanta Old Town, Khlong Chak waterfall, the main snorkelling day trips, mangrove kayaking, and what the nightlife and remote-work scene actually look like, with current 2026 prices throughout. It’s the pillar guide for Koh Lanta on outthailand.com, so it links out to deeper guides beneath it as we go.

What are Koh Lanta’s best beaches?
The west coast of Lanta Yai (the main inhabited island) runs one long chain of beaches, and most visitors base themselves on whichever stretch matches their pace. Long Beach (known locally as Phra Ae) is the island’s longest and most developed stretch, wide and sandy with restaurants and bamboo sunbeds, and the default choice for a first stay. Klong Nin, further south, is calmer, with powdery sand and a mid-range mix of guesthouses and beach restaurants. Kantiang Bay, near the island’s southern end, is a scenic crescent bay backed by green hills and holds several of Koh Lanta’s higher-end resorts. Bamboo Bay, the southernmost beach before the national park gate, is the quiet one: secluded and thin on infrastructure. All are free to walk; you only pay for a sunbed, food, or watersports gear. For the complete list, including which beach suits families versus long-stay nomads, see outthailand.com’s Koh Lanta beaches guide, and for where to book a room near any of them, see the where to stay in Koh Lanta guide.
What is there to do at Mu Ko Lanta National Park?
Mu Ko Lanta National Park covers the southern tip of Lanta Yai and is built around a short network of trails leading to the Laem Tanod (Tanod Cape) lighthouse, officially the Phrachonlathup Waithikarn lighthouse, which sits on rocky headland cliffs above the Andaman Sea. Foreign adults pay around ฿200 (about US$6), with a reduced rate near ฿100 for children and ฿40 for Thai nationals, plus a small ฿20 motorbike or ฿30 car fee if you drive in. The park is open roughly 8am to 5pm daily, with last entry generally by 5:30pm. The lighthouse trail is short and manageable for casual hikers, and the headland is a good spot for sea-eagle and hornbill sightings. Rangers sometimes sell tickets at makeshift huts near the entrance rather than the official booth, so ask for a printed ticket. The same day-ticket, per current park signage, also covers the trail to Khlong Chak waterfall inland, so plan the two together.
What is Khlong Chak waterfall like?
Khlong Chak is a jungle waterfall reached by a roughly hour-long forest trail from a marked trailhead in the island’s south-central interior, with several smaller cascades and swimming pools along the way before the main falls. The official entrance fee is around ฿200 (about US$6) per adult, included if you already hold a same-day national park ticket, since Khlong Chak sits within the same protected area as the lighthouse trail. It’s a moderate hike best done in trekking sandals rather than flip-flops, and flow is strongest in the rainy season (roughly June to November), slowing to a trickle in the driest months. Watch for unofficial fee collectors near the trailhead; a legitimate visit gets you a printed ticket.
What is Lanta Old Town?
Lanta Old Town (Ban Si Raya) is a 19th-century Chinese-Thai trading port on the island’s sheltered east coast, built by Chinese merchants, Chao Lay sea gypsies, and Thai-Muslim fishing families who settled the coastline over generations. Its single main street is lined with century-old teak shophouses, many built on stilts directly over the tidal shoreline, with lanterns and small Chinese shrines still marking the older buildings. It’s free to wander, with cafés, seafood restaurants, and guesthouses now occupying the old trading houses, and it’s at its best around sunset, when the waterside restaurants catch the light off the Andaman. It’s a short scooter ride from the west-coast beaches and pairs naturally with a half-day covering the mangroves at Thung Yee Peng, just up the coast.
What are the best day trips from Koh Lanta?
Koh Lanta sits within a single speedboat run of several of the Andaman’s best offshore snorkelling spots, and most trips leave from Saladan pier or a hotel pickup.
Koh Rok and Koh Haa are the standout snorkelling combination, sold as a full-day speedboat trip running roughly ฿1,700-2,100 (about US$52-64) per person, including buffet lunch, snorkel gear, and hotel transfers, plus a separate ฿400 (about US$12) national park entrance fee paid in cash on the day. Koh Rok’s two islets ring a lagoon of clear, shallow water and a fine white-sand beach, while Koh Haa’s five limestone islets have some of the area’s better coral and reef-fish visibility, with a swim-through cavern that doubles as a popular dive site.
The Emerald Cave (Tham Morakot) on Koh Mook is the other must-do, usually sold as a 3-4 island day, running roughly ฿1,500-1,900 (about US$45-58) per person including lunch and transfers. The cave itself is a tidal sea cave you swim into through a dark, roughly 80-metre tunnel that opens into a hidden emerald-green lagoon ringed by cliffs, best timed around low-to-mid tide; trips typically combine it with nearby Koh Kradan, Koh Ngai, or Koh Chuek. For the wider set of island-hopping options across Krabi province, see outthailand.com’s things to do in Krabi guide.
Both trips run outside high season too, but with far fewer departures and choppier seas from roughly May to October, so confirm an operator is running before you commit to a date.
What is mangrove kayaking at Thung Yee Peng like?
The Thung Yee Peng mangrove forest, on the northeast side of the island near Sri Raya, is Koh Lanta’s main mangrove-kayaking spot, a network of tidal channels lined with dense mangrove roots and small floating fishing communities. Half-day tours cost roughly ฿1,300-1,800 (about US$39-54), typically covering transfers, a longtail boat out to the forest, kayak rental, a guide, and fruit or water, plus a small local entrance fee of around ฿20-40 collected at the mangrove community’s own booth (separate from the national park). Tours usually pair the paddle with a stop at a sea cave or nearby Koh Talabeng’s limestone cliffs, and it works well as a half-day add-on to Lanta Old Town, since both sit on the same side of the island.
What is Koh Lanta’s nightlife actually like?
Low-key, and that’s the point. There’s no club strip here the way there is on Phuket’s Bangla Road or Koh Phangan’s Full Moon beach; instead the scene is beach bars strung along Long Beach, Klong Khong, and Klong Nin, most doing fire shows, reggae, and a sunset happy hour rather than a big night out. Why Not Bar, on Long Beach, is a well-known spot for fire performances and live music, and the Ozone Beach Bar runs a regular sunset DJ session. Drinks run from roughly ฿100-150 (about US$3-4.50) for a beer or basic cocktail. Expect most places to wind down well before 1am, and don’t expect much at all in the May-October low season, when many bars close for the year.
Can you work remotely from Koh Lanta?
Yes, it’s a genuine stop on the Thailand digital-nomad circuit, not just a beach holiday island with wifi. The anchor is KoHub, a dedicated coworking space near Long Beach with air-conditioned desks, an outdoor garden work area, fast fibre internet, an on-site café, and coliving bungalows a short walk from the beach, plus an active community of long-stay remote workers. KoHub and much of the nomad-facing infrastructure runs on a seasonal rhythm, generally operating through the November-to-April high season and scaling back over low season, so check current opening dates before planning a low-season stay. Outside KoHub, a run of west-coast cafés offer fibre wifi and laptop-friendly seating, and the island’s slower pace and lower cost of living than Phuket or Koh Samui are a big part of its appeal to long-stay remote workers.
Honest downsides of visiting Koh Lanta
- Low season (roughly May-October) shuts a lot down. A large share of resorts, restaurants, dive shops, and the main coworking space scale back or close, ferry and speedboat services run reduced schedules, and the sea can turn rough and murky with flotsam. More businesses stay open year-round than before, but it’s a quieter, patchier island outside November-April.
- The island is spread out and needs a scooter. Lanta Yai runs roughly 30km north to south along one main road; the beaches, Old Town, waterfall, and national park are too far apart to walk between. Scooter rental runs about ฿200-300 (US$6-9) a day; songthaews and taxis fill the gap at higher cost.
- Nightlife is genuinely quiet. If you want late clubs and a big party scene, Koh Lanta isn’t it, that’s Phuket or Koh Phangan territory. Here it’s sunset drinks and an early night.
- Getting there means one car ferry crossing, not two. As of July 2026, reaching Koh Lanta by road from Krabi means one short car ferry from Koh Klang to Koh Lanta Noi, then the Sirilanta Bridge onto Koh Lanta Yai; the second ferry was replaced by that bridge back in 2016, so older guides that mention two crossings are out of date. Long queues are still possible at the remaining ferry in peak season (December-March). A further bridge cleared a mangrove-land approval in June 2026, with pile driving expected later in 2026 and opening targeted for 2029, which would eventually replace the last car ferry too.
FAQ
How many days do you need in Koh Lanta?
Three to four days covers the essentials: one day for the west-coast beaches, one for the national park and lighthouse (adding Khlong Chak waterfall on the same ticket), one for a boat day trip to Koh Rok/Koh Haa or the Emerald Cave, and a half-day for Lanta Old Town and mangrove kayaking. Koh Lanta is a low-key, spread-out island built for slowing down rather than checklist tourism, so a week is common among the long-stay and digital-nomad crowd.
What is the best beach in Koh Lanta?
It depends on what you want. Long Beach (Phra Ae) is the most developed, with the widest choice of restaurants and beach bars. Klong Nin is calmer with powdery sand and a laid-back mid-range crowd. Kantiang Bay is the scenic, resort-heavy southern hub with a crescent bay backed by hills. Bamboo Bay, further south again, is the quietest and the last beach before the national park gate. For a full breakdown of every beach on the island, see outthailand.com’s Koh Lanta beaches guide.
How much does Mu Ko Lanta National Park cost?
Foreign adults pay around ฿200 (about US$6), with a reduced rate near ฿100 for children and ฿40 for Thai nationals; a motorbike is an extra ฿20 and a car ฿30. The park is open roughly 8am to 5pm daily, with last entry generally by 5:30pm. The fee covers the Laem Tanod lighthouse trail at the island’s southern tip and, per current signage, the Khlong Chak waterfall trail on the same day.
Is Koh Lanta worth visiting over Phi Phi or Krabi?
Choose Koh Lanta if you want long, quiet beaches, a real off-duty pace, and a base to day-trip out to Koh Rok, Koh Haa, and the Emerald Cave without the crowds of Phi Phi or the climbing-town buzz of Krabi’s Railay. Choose Phi Phi for nightlife and iconic viewpoints, or Krabi/Railay for rock climbing and easier mainland access. Many travellers combine Koh Lanta with Krabi as a slower add-on rather than picking one over the other; see outthailand.com’s things to do in Krabi and best islands in Thailand guides for how the region’s islands compare.
Do you need a scooter on Koh Lanta?
Yes, effectively. The island runs about 30km north to south along a single main road, and the west-coast beaches, Old Town, waterfall, and national park are all spread far enough apart that walking between them isn’t realistic. Scooter rental runs roughly ฿200-300 (about US$6-9) a day. Songthaews and taxis cover the gaps if you’d rather not drive, at higher cost.
What is Koh Lanta’s nightlife like?
Low-key by design. There’s no club strip like Phuket or Koh Phangan; instead you get beach bars with fire shows, reggae, and sunset happy hours, concentrated on Long Beach, Klong Khong, and Klong Nin. Why Not Bar and the Ozone Beach Bar are among the better-known sunset spots. Expect most nights to wind down by midnight rather than run until dawn.
Can you work remotely from Koh Lanta?
Yes, it’s an established stop on the Thailand digital-nomad circuit, built around KoHub, a dedicated coworking space with coliving bungalows near Long Beach, alongside nomad-friendly cafés with fibre wifi across the west coast. Note that KoHub and a chunk of the nomad-facing infrastructure runs seasonally in step with the high season (roughly November to April); the low season is quieter for coworking options.
Is Koh Lanta good for families?
Yes. The main west-coast beaches have gentle, shallow entry, especially Long Beach and Klong Dao, and the island’s slower pace and lower party profile than Phi Phi or Phuket suit families with young kids. Boat day trips (Koh Rok, Koh Haa, the Emerald Cave) can run long for small children, so check operator age guidance before booking, and Bamboo Bay’s calmer waters are worth the extra drive south.
Conclusion
Koh Lanta rewards a slower trip: a few days on the west-coast beaches, a day at the national park and lighthouse with the waterfall on the same ticket, a sunset dinner in Lanta Old Town, and one boat day out to Koh Rok, Koh Haa, or the Emerald Cave.
