Things to Do in Koh Lanta: 8 Best Activities (2026 Guide)

Koh Lanta Yai is a long, forested island in Krabi province, accessible from the mainland by a pair of short car-ferry crossings. The west coast has the best beaches; the east side faces a mangrove-lined estuary. Old Lanta Town on the southeast tip preserves a row of Malay-Chinese wooden shophouses that is one of the most atmospheric old quarters in the Andaman. Here are 8 things worth your time on Koh Lanta.

1. Long Beach (Hat Phra Ae)

Koh Lanta’s best-known beach runs for 4 km down the northwest coast — the widest stretch of sand on the island, with clear water and consistent surf in the October–April peak season. Sunsets here face directly west across the Andaman Sea. The beach road has a good mix of guesthouses, open-air restaurants, and dive shops.

2. Mu Koh Lanta National Park (Southern Tip)

The national park covers the southern third of the island. The main area has a lighthouse, viewpoints over the narrow strait separating Koh Lanta from Koh Rok, coral reefs accessible to snorkelers directly from the beach, and forested hills with hornbills and monitor lizards. Entry fee ฿200. The park road is a scenic drive from the main beach area.

3. Koh Rok Snorkeling Day Trip

Koh Rok Noi and Koh Rok Yai are twin islands 47 km south of Koh Lanta — part of the national park, only accessible by longtail or speedboat. The coral gardens between the two islands are among the healthiest on the Andaman Coast. Tour operators in Lanta run full-day trips; visibility runs 10–20 m in the dry season.

4. Hin Daeng and Hin Muang Diving

The two best dive sites in the region — submerged pinnacles 45 km south of Koh Lanta. Hin Daeng (“Red Rock”) is known for leopard sharks, eagle rays, and occasional whale shark passes; Hin Muang (“Purple Rock”) has one of the deepest drop-offs in the Andaman. Day trips require a PADI OW or equivalent; visibility consistently 20–30 m.

5. Old Lanta Town

The original village on the southeast coast — a crescent of 19th-century wooden shophouses on stilts over the water, built by Malay-Chinese traders. Today it holds a concentration of small guesthouses, coffee shops, and artisan stores. The pier looks across to the mainland mangroves. A slow afternoon stroll rather than a half-day trip.

6. Sea Kayaking in Mangrove Tunnels

The east coast of Koh Lanta, facing the mainland, is dense mangrove. Guided kayak trips run through tidal channels and cave systems — the most impressive is Tham Khao Maikaew cave, reachable by kayak at high tide. Half-day trips depart from the main beach area (around ฿500–฿800 per person).

7. Sunset from Kantiang Bay

Kantiang Bay on the southwest coast is a deep, sheltered cove — quieter than Long Beach, with clear water and less development. The clifftop above the south end of the bay gives a 180-degree Andaman sunset view. A good end to a drive down the west coast road.

8. Lanta Elephant Sanctuary

A small-group ethical sanctuary at the north end of the island — rescued elephants in a forest environment, no performances or riding. Morning visits include feeding and bathing in the river. Pre-booking essential; groups are kept very small. One of the more thoughtfully run sanctuaries on this stretch of coast.
