About Koh Rin North
Koh Rin North is the north-side training ground on Koh Rin, with a sheltered bay, North Rock just beyond it, and enough reef structure to make the dive more than a basic practice stop. It works well as a Pattaya Far Islands boat day when you want calm water first and a deeper step-up once the bay is done.

Local Intel For Koh Rin North
Community notes to help plan your visit.
Scuba
The north bay is the open-water training line, with North Rock as the deeper continuation for divers who want more structure.
Freedive
The bay is the only sensible shallow-water line, but the site is fundamentally a scuba outing rather than a freedive destination.
Snorkel
Koh Rin Bay is the best snorkel line on calm days, but the interesting structure sits deeper on North Rock.
