Blue Lagoon - Perhentian Islands

Blue Lagoon is a nice, relaxed dive, especially if you're keen on finding some of the smaller residents. We’ve seen a decent range of nudibranchs here, including the bicolor, often tucked into the crevices of the organ pipe and honeycomb corals. Keep an eye out for black sea cucumbers and blackspotted sea cucumbers inching along the sandy patches, and if you’re lucky, a green turtle might cruise by. It's a gentle site, good for a leisurely exploration, particularly if you’re getting back into the swing of things or just want a chill dive without strong currents to worry about.
