About Koh Bon, The Bay
Koh Bon, The Bay is the sheltered bay dive at Koh Bon, offering the calmest and shallowest water on the island and a softer alternative to the exposed ridge. Expect a sloping coral reef, small reef life, and occasional manta or whale shark encounters when the season and sea state line up. It is a strong guided boat dive for newer divers and snorkelers when the bay is settled, with the ridge side of Koh Bon reserved for much more exposed conditions.

Scuba Diving
A relaxed guided reef dive fits the bay well, especially for photographers, newer divers, or sunset and night dives when the sea is settled.
Freediving
Freediving is only sensible in the shallow, sheltered bay on very calm days and should stay operator-led rather than independent.
Snorkeling
The sheltered bay is the snorkel-friendly part of Koh Bon and suits less experienced snorkelers when the sea is calm.
