Best Beaches in Koh Lanta: From Bustling Long Beach to Hidden Gems

koh lanta beaches

Koh Lanta, tucked away in Thailand’s Andaman Sea, is often described as one of the country’s most relaxed islands. Unlike Phuket or Koh Phi Phi, it has a slower pace and a down-to-earth vibe that attracts couples, families, backpackers, and long-term travelers alike. One of the island’s greatest charms is its beaches. With more than a dozen stretches of sand running down the west coast, each beach offers something unique—from lively sunset bars to secluded coves where the only sound is the ocean.

This guide covers the best beaches on Koh Lanta, what makes each special, and tips to help you choose where to stay and play.

  • Why it’s great:

    • Long, wide stretch of soft sand.

    • Shallow waters—safe for kids.

    • Plenty of beachfront resorts, restaurants, and massage huts.

    • Walking distance to town for shops and the pier.

Klong Dao is the most developed beach on Koh Lanta but still feels relaxed compared to other Thai islands. Families love it for the calm water and amenities, while couples enjoy sunset cocktails without straying far from their hotel.

Long Beach is the most popular spot for younger travelers and those who want some atmosphere without going full-on party mode. The beach is wide and perfect for swimming. At night, it lights up with beach bars and reggae beats.

Best for: Backpackers, social travelers, and couples looking for a lively but not overwhelming beach scene.

    • Popular with digital nomads and long-term travelers.
