About This Anchorage

Phang Nga Bay is one of the world's most spectacular cruising grounds — a UNESCO-designated Ramsar wetland site dotted with hundreds of dramatic limestone karst islands rising vertically from the sea. The bay is the backdrop for James Bond Island (Koh Tapu) and contains hidden lagoons (hongs) accessible only by kayak at certain tidal states. The area is part of Ao Phang Nga National Park with anchoring fees payable at the park office. The bay's sheltered nature makes it excellent in all seasons.

Set Your Anchor Alarm to 80m

In Phuket and Phang Nga Bay, the 2–3m Andaman tidal range means your boat's position changes dramatically with the tide. Safety Anchor Alarm monitors your GPS position continuously so you can explore the hongs, beaches, and karst formations with complete peace of mind.
