Muck diving in the Lembeh Strait is a bucket-list experience for every serious diver and underwater photographer. These black sand bays, coral outcrops, and rubble fields harbour an extraordinary concentration of rare and unusual marine life found almost nowhere else on earth. Whether it’s your first visit or your tenth, the Lembeh Strait will surprise you every single dive.
Divers at NAD-Lembeh regularly encounter frogfish, rhinopias, mimic octopus, blue-ringed octopus, wonderpus, flamboyant cuttlefish, hairy frogfish, ghost pipefish, dragonets, bobbit worms, and an astonishing variety of nudibranchs. But Lembeh is far more than muck diving — we also explore the island’s wall dives, reef dives, technical dive sites, and run dedicated blackwater night dives, where the open ocean delivers pelagic larvae and deep-water creatures unlike anything you’ll see in the daytime.
Diving Tips for the Lembeh Strait
The Lembeh Strait is famous for its dive guides and their pointing sticks — essential tools in the right hands. Our trained guides use them to gently coax rare critters into view for photographers without causing stress to the animal. This matters: a stressed critter moves on, and you won’t find it again on your next dive. Wherever you dive in Lembeh, please remind your guides to always return animals to exactly where they were found and handle them with care.
Underwater Photography Etiquette on Muck Dives
First-time muck divers in Lembeh often get so excited they fire off 200 shots on a single dive. We get it — but fewer, better-composed shots will serve you much more than a memory card full of blurry frogfish. If you feel like you’re machine-gunning the critters with your strobe, ask our guides or management for a quick tips session — we’re always happy to help you get the shot. Excessive flash hasn’t been proven to harm critters, but with up to nine boats hitting some sites in a day, let’s be considerate. The mantra at NAD: Stop. Look. Think. Shoot.

A Few More Tips for Diving in Lembeh
- Black sand and silt ruins photos fast once stirred up. Keep a head-down, fins-up position as you move between subjects. If you rest on the sand to frame a shot, use your breath and BCD to lift back into the water column — don’t kick off the bottom.
- Be a good dive buddy. If someone’s mid-shot and you want a look, wait your turn. Swimming over a subject and kicking sand onto it is more common than you’d think, and nobody wins.
- Share the critters your guide finds. Take your first few frames, step back and let others have their turn, then return to finish your set. If you need more time with a subject, talk to your guide or the management — we’ll do our best to arrange it.
- Found a critter before your guide did? Finder’s keepers — or not. That’s a debate best settled on the boat over a Bintang.
- If a guide from another boat tries to pull you away from your subject, hold your ground politely. We don’t believe in that practice at NAD, and if one of our own guides ever does it to you, please tell us immediately.
- Non-photographers deserve critter time too! They have short attention spans and move on quickly, so let them have a look first before you raise the camera.
- Lembeh’s coral formations and algae beds deserve respect. Even that boring-looking algae patch on the sand is probably sheltering a newly settled frogfish underneath.
- No gloves — this is a firm NAD rule. Gloves make divers less careful about what they touch. Scorpionfish and other venomous species can sting right through them anyway. Gloves off, hands to yourself.
Muck diving in Lembeh is as much a social experience as it is a photographic one — these recommendations exist to help everyone on the boat get the most out of every dive, and to keep this incredible ecosystem healthy for the divers who come after us.
