About Koh Lak Ngam

Koh Lak Ngam is part of the Chumphon dive cluster near the Ngam islands. Its reef is in excellent condition due to minimal human impact, with good coral coverage and typical Gulf reef fish. A solid second-dive option when combined with the nearby Ngam islands or HTMS Prab wreck.
