Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Banana Bay offers some of Similan Islands's richest reef diving. Water ranges 29-31°C, warmest April, May, June.
Banana Bay, tucked into the Similans, often gets overlooked for some of its flashier neighbours, but we think that’s a mistake. This is our quiet favourite, especially for those days when you just want a relaxed, easy dive after a bit of a current-filled morning elsewhere. The bay itself is a gentle slope, mostly sand, but don't let that fool you. Spend some time really looking, and you’ll be rewarded. We love it for the macro and the sheer chill factor. Think blackspotted sea cucumbers inching along, little striped triplefins perched on coral rubble, and those tiny bicolor blennies popping their heads out of holes. It’s a fantastic spot for photographers who want to slow down and really compose a shot. We’ve often seen big garrupa cruising through the sandy patches, and giant morays peeking from under the scattered coral heads. Our tip: go early or late in the day. The light is softer, and the five-lined snapper schools seem to move more deliberately, making for some lovely silhouettes against the sun. It’s perfect for newer divers building confidence, or anyone who just wants an hour of pure, unhurried underwater observation.
