The park contains the largest remaining primary mangrove forest in Thailand.
Many of the park's islands contain 'hongs,' which are hidden lagoons reachable only through low cave tunnels during specific tidal conditions.
The floating village of Ko Panyi was established by Indonesian fishermen in the late 18th century.
The limestone karsts in the bay are composed of sedimentary rock formed roughly 280 million years ago.
The water in the bay remains relatively shallow, averaging 5 meters in depth.
Local sea gypsies, known as Moken, have historically inhabited areas surrounding the bay for generations.
The park was designated as a Ramsar Site in 2002 due to its international importance as a wetland habitat.
Ao Phang Nga National Park is a marine protected area covering approximately 400 square kilometers in the Andaman Sea. It is defined by its extensive mangrove forests and 42 karst limestone islands protruding from shallow, turquoise waters. The park is home to the floating village of Ko Panyi, which is built entirely on stilts over the water. Sea caves and hongs—collapsed cave systems accessible only by canoe—are primary geological features. Wildlife includes over 100 bird species and diverse marine life inhabiting the complex root systems of the mangroves. The park serves as a critical buffer for coastal ecosystems against erosion and storm surges. It is globally recognized for the 'James Bond Island' (Khao Phing Kan), a prominent karst pinnacle featured in 1974 cinema. The tidal environment dictates accessibility to many inland lagoon areas within the karst formations.

Coordinate your trip with low tide to ensure access to the sea caves via kayak.
Bring a waterproof bag for electronic devices, as boat trips often result in splashing.
Use reef-safe sunscreen to protect the fragile marine ecosystem.
Avoid taking shells, coral, or limestone fragments as souvenirs, as this is strictly prohibited and damages the ecosystem.
Some smaller sea caves may be inaccessible during extreme high tides.
Cover shoulders and knees if visiting the residential areas of Ko Panyi; remove footwear before entering communal structures.
