About Loh Namu

The Peninsula of Loh Namu offers an interesting dive for those who are into large groupers and napoleon wrasse. Dive around this point from south to north, at a depth of some 28 m and always just before high tide. Almost guaranteed to see some big ones! Most of the fish are found near the southern corner where some large boulders are spread out over the drop-off and a few caves offer additional hiding places. We have seen some of the largest coral trout here, hanging out side by side with malabar groupers and huge male Napoleon wrasse which may be aggregating here to spawn. Also wide soft coral as a carpet and the giant gigas clam in 8 meters depth.

Dive Site Hazards

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
