Defined by emerald lagoons, steep limestone formations, and sheltered bays, Ang Thong Marine Park stretches across more than 40 islands and nearly 100 square kilometres of the Gulf of Thailand. Reached by boat from Koh Pha Ngan or Koh Samui, the park presents a chain of dramatic islands shaped by water and wind. Kayaking and hiking open access to hidden inlets and elevated viewpoints, while snorkelling and scuba diving move through clear waters filled with colourful fish, coral gardens, and varied marine life. The park’s headquarters are based on Koh Wua Talab, where a small visitor centre and jungle trails lead through dense forest to sweeping coastal views.
