Surat Thani / Ang Thong Islands

Mu Ko Ang Thong National Marine Park

An archipelago of about 40 islands around 20 km from Koh Samui, reached on day boat trips from Samui or Koh Phangan. On Ko Wua Ta Lap a 400-metre trail climbs to a sweeping viewpoint, and on another island steps lead up to look down on an emerald lagoon ringed by cliffs; boats can be cancelled in rough seas, so check before booking.
