Thailand — Phuket & Phang Nga Bay

Anchorages in Phuket & Phang Nga Bay

From Phuket's cruising hub at Ao Chalong and the scenic bays of Nai Harn and Kata, through the karst wonderland of Phang Nga Bay with its hidden lagoons, James Bond Island, and tranquil Koh Yao islands. Thailand's premier Andaman Sea sailing region.

Andaman Sea Season & Phang Nga Bay National Park Rules

Best sailing November–April (NE monsoon) — calm seas and excellent visibility. SW monsoon (May–October) makes most west-facing bays unsafe. Tidal range 2–3m semi-diurnal — always set anchor scope for high-water depth. Ao Phang Nga National Park requires entry fees (~300 THB per person per day). Anchoring on coral or damaging mangroves is illegal under Thai environmental law. Check in at Ao Chalong customs office immediately on arrival in Thailand.
