Koh Lanta Yai is the unhurried alternative in the Andaman Sea cluster that includes Koh Phi Phi (famous, crowded, recovered from its tsunami devastation) and Krabi’s mainland beaches (excellent, busier). Lanta is longer, more slowly paced, and less aggressively marketed — an island that rewards those who make the extra journey south from the Krabi pier to find it. Long Beach (Hat Khlong Dao in Thai — “Khlong Dao Beach”) on the island’s northwestern coast is the finest of Lanta’s five or six good beaches: 4 kilometres of white sand, calm water sheltered from the open swell by the island’s position within the Lanta archipelago, and a backdrop of casuarina pines and coastal vegetation that provides natural shade and frames the beach in green.
The Andaman Sea at Koh Lanta in the dry season (November–April) reaches its most beautiful form. The water clarity here is exceptional — the same geological and current conditions that produce the Similan Islands’ extraordinary visibility are present further south. The colour transitions from pale turquoise over the sandy shallows to deep blue offshore, and the white sand bottom enhances the optical effect. Sunset at Long Beach faces west — the sun descending into the Andaman Sea between Koh Lanta Noi and the mainland, with the silhouettes of the offshore islands providing scale.
Koh Lanta has a character distinct from most of Thailand’s resort islands: a substantial Muslim fishing community (Chao Ley sea gypsies also have a settlement on the southeastern coast), a functional Thai town (Baan Saladan) with markets and local restaurants, a national park protecting the southern peninsula’s rainforest and beaches, and an atmosphere that is cosmopolitan but not aggressively commercial. The travellers who find Lanta tend to stay longer than they planned.
Access and Transport
Getting to Koh Lanta
The nearest airports are Krabi International Airport (KBV) and Phuket International Airport (HKT):
From Krabi Airport to Koh Lanta:
- Minivan to Krabi pier, then ferry to Koh Lanta (total approximately 1.5–2 hours)
- Alternatively, seasonal speedboat services direct to Koh Lanta’s main pier
From Phuket Airport to Koh Lanta:
- Minivan transfer to Koh Lanta available (approximately 3–4 hours overland and ferry)
- Or fly Phuket–Krabi then continue to Lanta
Ferries from Krabi to Koh Lanta:
- High-season ferries from Krabi Passenger Pier and Bang Rong Pier (Phuket) — approximately 1.5–2 hours to Baan Saladan pier on Koh Lanta’s northern tip
- Vehicle ferries also operate, allowing rental cars and scooters to be transported
From Baan Saladan pier, Long Beach (Khlong Dao) is approximately 3–5 km south — accessible by songthaew, tuk-tuk, or taxi.
Best Time to Visit
Koh Lanta’s Andaman Sea position creates a clear seasonal pattern:
- November to April: The dry season — the ideal beach season. Calm water, excellent visibility, consistent sunshine, and temperatures of 28–32°C. The beach and resort infrastructure are fully operational.
- December to February: Peak season with maximum visitors. Book accommodation in advance.
- May to October: Monsoon season. The southwest monsoon brings rain, rough seas, and choppy water to the Andaman coast. Most Koh Lanta resorts close fully in June–October. The island is very quiet and cheap; the beach is not swimmable in the worst conditions.
- October and November: The transition season. Weather can be variable but improving rapidly.
Accommodation
Long Beach has a well-developed resort strip:
- Layana Resort and Spa: One of Koh Lanta’s finest properties — an adults-only boutique resort on Long Beach with exceptional pool, spa, and restaurant.
- Lanta Casuarina Beach Resort: A comfortable mid-range option named for the casuarina pines framing the beach.
- Crown Lanta Resort: Upscale beachfront accommodation with good facilities.
- Numerous bungalow operations: Long Beach’s original character was defined by its bamboo bungalow operations — simple huts with mosquito nets and cold showers, directly on the sand. Several of these still operate alongside the more developed resorts, catering to budget travellers.
- Rawi Warin Resort (southern beaches): Koh Lanta’s most luxurious property is on the southeastern coast — a large resort with multiple pools and direct access to a quieter section of beach.
On the Beach and Beyond
Snorkelling and Diving
Koh Lanta is one of Thailand’s premier diving destinations:
- Koh Ha Yai: An uninhabited island 30 km south of Lanta with five dive sites — caverns, tunnels, walls, and a lagoon with extraordinary marine life (including whale sharks, leopard sharks, and manta rays in season). One of the Andaman Sea’s finest dive destinations.
- Hin Daeng and Hin Muang: Two submerged pinnacles 70 km south of Lanta, in the open sea — among Southeast Asia’s finest dive sites. Manta rays congregate here; whale shark sightings are frequent.
- Mu Ko Lanta National Park reefs: The reefs around the southern islands of the national park are excellent for snorkelling and shallow diving.
Multiple dive centres in Baan Saladan and on Long Beach offer PADI courses and day trips.
Mu Ko Lanta National Park
The southern peninsula of Koh Lanta Yai is protected as a national park. The park includes the undeveloped southern beaches (accessible by hiking or boat), rainforest walks with bird life, and the Tham Khao Mai Kaew cave system — a series of caverns with stalactites and stalagmites navigable with a guide and headlamp.
Old Town (Baan Lanta / Ko Lanta Old Town)
The old settlement on the island’s southeastern coast — a stilted fishing village of Chinese shophouses and old Thai architecture built over the water — is one of the most atmospheric historic settlements in the Andaman Sea region. The wooden boardwalk connecting the buildings, the fishing boats in the bay, and the hill behind the village combine in a landscape unchanged in its essentials from a hundred years ago.
Kayaking to Small Islands
Day trips by kayak or longtail boat to the smaller islands of the Lanta archipelago — Koh Rok (brilliant white sand and excellent snorkelling), Koh Ngai, and the Four Islands — are the best-value day excursions from Koh Lanta. The snorkelling at Koh Rok in particular is among the best available on day trips in the region.
Visitors Ask
Is Koh Lanta good for families? Excellent — Long Beach’s calm water, the island’s relatively low-key atmosphere, and the absence of heavy nightlife make it one of Thailand’s most family-appropriate Andaman islands. The national park, snorkelling, and cave exploration provide good activities for children.
How does Long Beach compare to the beaches of Phi Phi or Railay? Phi Phi’s Maya Bay has more dramatic scenery but is increasingly managed for tourists. Railay has extraordinary cliff and cave scenery. Long Beach is the best choice for an extended stay of a week or more — the beach is excellent, the atmosphere is relaxed, and there is more to do than simply admire the view.
Are there ATMs and reliable internet on Koh Lanta? Yes — Baan Saladan has several ATMs and a functioning commercial centre. Internet connectivity (4G mobile) is good throughout the resort areas of the island. The Old Town area has slower connectivity.
