Angthong National Marine Park: Private Speedboat Charters & Emerald Lake

Gulf of Thailand marine expedition: 42 limestone islands, Talay Nai emerald seawater lagoon, Koh Mae Ko viewpoint, sea kayaking, and luxury catamaran cruises.

The Inspiration Behind 'The Beach'

Spanning 102 square kilometers of crystalline azure sea in the Gulf of Thailand, Ang Thong National Marine Park comprises 42 uninhabited limestone islands crowned with lush tropical rainforests. While Alex Garland set his famous novel 'The Beach' here, the subsequent film was shot in Maya Bay; however, Angthong remains the quintessential untouched tropical archipelago.

Key Island Highlights

  • Talay Nai (Emerald Lake) at Koh Mae Ko: A landlocked saltwater lake hidden inside an extinct collapsed sinkhole cavern. A steep but well-built wooden staircase leads visitors to an elevated viewpoint overlooking the surreal neon-emerald water surrounded by vertical limestone walls.
  • Wua Ta Lap Island & Viewpoint: The headquarters of the national park, featuring a magnificent white sand beach, sea turtle nesting grounds, and a demanding 500-meter hiking trail leading to the park's highest summit with panoramic vistas of all 42 islands.
  • Sea Kayaking & Hidden Coves: Guided sea kayaking along vertical rock arches, sea caves, and secluded coral beaches at Koh Sam Sao (Tripod Island).

Vessel Formats: Big Boat vs Speedboat vs Sailing Yacht

Thailand DMC arranges three charter tiers departing from Nathon, Bangrak, or Petcherat Pier: high-speed speedboats (45-minute crossing), traditional multi-deck wooden touring boats (stable and relaxed for seniors), and luxury sailing catamarans complete with gourmet catering, champagne, and paddleboards for VIP travelers.
