Koh Lanta
Koh Lanta is the Andaman coast's most laid-back island destination, beloved by families, couples, and anyone seeking beautiful beaches without the party scene. The island is actually two islands (Koh Lanta Noi and Koh Lanta Yai) connected by a bridge, with all tourist development on the larger Lanta Yai. Its long west coast features a string of gorgeous beaches, each quieter as you head south, culminating in the wild beauty of Mu Ko Lanta National Park. The charming Old Town on the east coast preserves the island's multicultural heritage.

Beaches
Where Koh Lanta is strongest
Beaches vary considerably across the island. The labels indicate what each beach suits best — useful for matching your priorities.
Long Beach (Phra Ae)
The most popular beach on Koh Lanta with a wide strip of golden sand stretching for 4 kilometers. Well-developed with a good range of restaurants, beach bars, and accommodation, yet never feeling overcrowded. Great swimming and spectacular sunsets.
Klong Dao Beach
The northernmost tourist beach, closest to the pier, with calm shallow water that's perfect for families with young children. The sand is soft and wide, and the sea is shallow enough to wade far out safely.
Kantiang Bay
A stunning horseshoe-shaped bay in the south of the island, home to the luxury Pimalai Resort. The beach is beautifully framed by jungle-covered hills and offers excellent snorkeling at the rocky ends. One of Lanta's most photogenic spots.
Bamboo Bay (Ao Mai Pai)
A remote, less-visited beach near the national park at the southern tip of the island. Backed by dense jungle with just a handful of rustic bungalow operations. The kind of untouched beach that is increasingly rare in Thailand.
Klong Khong Beach
A bohemian-flavored beach popular with long-stay travelers and digital nomads. The rocky shore at low tide reveals interesting tide pools but makes swimming better at high tide. Known for reggae bars and a creative, alternative atmosphere.
