WHY ANG THONG

One sea day. Several different ways to experience it.

Mu Ko Ang Thong National Marine Park is a protected archipelago west of Koh Samui. Its mix of beaches, limestone scenery, viewpoints, kayaking and snorkeling makes it a strong all-round day-trip destination for groups whose members want different levels of activity.

HIGHLIGHT

42-island protected archipelago

DNP describes Mu Ko Ang Thong as a 42-island limestone archipelago covering about 102 km² in the Gulf of Thailand.

HIGHLIGHT

Koh Mae Ko · Thale Nai

A steep stair route leads to the viewpoint over the enclosed saltwater lagoon known as the Inner Sea; swimming in the lagoon is not permitted.

HIGHLIGHT

Koh Wua Talap viewpoint

TAT describes the summit route as a demanding roughly 500-metre climb, rewarding visitors with a broad panorama across the archipelago.

HIGHLIGHT

Kayak, snorkel or slow the day down

The destination supports different paces: scenic cruising and beach time, kayaking/snorkeling when conditions allow, or higher-effort viewpoint climbs.
