Muck Diving

Muck diving is a specialized type of diving that takes place over sandy, silty, or volcanic bottoms — often in areas that look unremarkable at first glance. But these "mucky" environments are actually hotspots for bizarre, rare, and highly camouflaged marine life that you won't see on coral reefs.

Around Gili Trawangan, we've discovered exceptional muck diving sites that rival more famous destinations. Our SSI & PADI certified guides know exactly where to look for the most sought-after critters, and we specialize in small groups (max 4 divers per guide) so everyone gets a great view and photo opportunities.

Each muck dive is slow-paced and focused on observation. We'll spend time hovering over sandy patches, peeking under debris, and examining sea grass beds — searching for well-camouflaged creatures that most divers swim right past. Patience is rewarded with extraordinary sightings.
