Boat-access reef and pinnacle with coral and blue-water edge.
Koh Haa #6 is a boat-access reef and pinnacle site with a shallow connecting ridge, broad coral cover, and a deeper blue-water edge that makes the route feel bigger than the map name suggests. It is a good fit for divers who want reef structure, a calm start, and the chance to see larger animals without leaving the protection of the Koh Haa islands.

Keep track of your depth as you cross the ridge and stay composed on the blue-water edge, especially if the current changes the route.

Scuba Diving
A reef-and-pinnacle dive with coral gardens, a shallow start, and a deeper outer face that rewards good trim and route awareness.
Freediving

Snorkeling
