Community notes to help plan your visit.
Scuba Diving
Best as a guided boat scuba dive. The rocky relief and grotto-style sections reward good buoyancy and an unhurried route.
Freediving
Not a freedive-first site. The deeper rock, current and overhead-style features make scuba the better fit.
Snorkeling
Snorkeling is better on shallower Hon Mun reefs nearby. This site is mainly worth planning as a scuba stop.
Chill / Non-diver
Treat it as a short boat-dive stop, not a lounge day.
