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.
Safety Notes
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.
Access Restrictions
Boat access only; Koh Haa trips are usually run as part of a larger island-hopping day trip.
Legal Notes
Check Koh Lanta marine-park access rules and seasonal trip planning before you go.
Community notes to help plan your visit.
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
The shallow side can work in calm conditions, but the deeper outer face is better left to scuba.
Snorkeling
The calm shallow areas can suit snorkeling on good days, especially on the inside of the islands.
