Why go

Ang Thong National Marine Park is a group of around forty limestone islands west of Samui. Steep cliffs, caves, white beaches and turquoise water make it one of the most beautiful places in the Gulf of Thailand.

One highlight is Thale Nai, a saltwater lake inside an island, reached by a short steep climb. Another is the viewpoint on Koh Wua Talab, a tough climb up steps and rock that ends with a panorama over the whole archipelago.

Many tours include kayaking among the islands, which is the best way to see the caves and cliffs up close.

The story

Ang Thong means 'golden bowl', a name often linked to the shape of the inner lake.

The park was created in the 1980s to protect its coral, mangroves and wildlife, including dusky langurs and sea eagles.

Many travellers say the islands inspired the hidden lagoon in the novel 'The Beach'.

Getting there

Day tours leave from Samui in the morning and return in the late afternoon. Speedboats are faster; larger boats are more comfortable in waves.

A suggested plan

1. MorningBoat to the park; first stop for snorkelling.
2. MiddayLunch on the island, then climb to the viewpoint.
3. AfternoonKayak, visit the inner lake and return.

Where to stay

Day trip from Samui; there's basic park accommodation for those who want to stay overnight.

Good to know

• Wear shoes with grip for the climbs.
• Bring sun protection and plenty of water.
• Take seasickness tablets if you're prone to it.
