Key Dive Site Facts
Dive Site Overview
Hin Bida reveals a distinct topography, characterized by a central round reef and several prominent 'fingers' extending towards the south-west. Many divers describe this formation as resembling a 'duck foot' when viewed from above, a helpful visual cue for navigation underwater.
An impressive diversity of hard and soft corals forms a vibrant, living habitat throughout the reef, supporting countless marine creatures. Diving here offers depths reaching up to 22-24 m (72-79 ft), accommodating a wide range of recreational certification levels. At its shallowest points, uppermost peaks can break the surface during low tide, indicating the variable vertical profile of the dive.
Expansive sandy bottom areas, especially in shallower sections, serve as crucial resting spots for specific species, contributing significantly to the site's ecological importance. These clear sand patches often provide opportunities for observing bottom dwellers and smaller critters.
Typical visibility here generally spans 15 to 30 m (49-98 ft), though conditions fluctuate with daily tidal flows and seasonal weather patterns. Currents can vary from mild to moderate, especially along the projecting 'fingers' of the reef, influencing drift dive potential.
Best Time to Dive
While Hin Bida is open for diving throughout the entire year, optimal conditions tend to emerge during specific months. March and December consistently show an 'Excellent' dive score, suggesting clearer waters and more stable weather.

Dive Difficulty & Safety Guidelines
Diving at Hin Bida requires adherence to specific guidelines designed to protect its fragile marine environment. As part of the Hat Noppharat Thara-Mu Ko Phi Phi National Park, this site falls under marine protected area regulations. Divers are strongly encouraged to avoid touching or disturbing any marine life, as many organisms are delicate and vulnerable to human contact. Practicing good buoyancy control is paramount to prevent accidental damage to corals and other seafloor inhabitants. Furthermore, collecting souvenirs such as shells or coral fragments is prohibited and harmful to the ecosystem. Always dispose of waste properly; never throw rubbish or food into the sea, especially near the reef, to preserve the natural balance. Using reef-safe sunscreen also contributes to safeguarding the coral and marine life.
