Muck diving the Dauin coast
Dauin is one of the world's best-known muck diving spots — frogfish, flamboyant cuttlefish, mimic octopus and ghost pipefish live on its black volcanic sand.
Muck diving means searching the sandy bottom for small, strange creatures, and Dauin's coastline is famous for it. Underwater photographers come from all over the world for macro life you rarely see elsewhere.
Most dives are shore or short boat dives from the resorts along the beach, so you can do two or three a day without long boat rides. Well-known sites include Mainit, where warm water from a hot spring seeps through the sand, and Cars, an artificial reef built from sunken car bodies.
Freediving and snorkelling are popular too, and many dive centres run beginner courses.

Good to know
- A local dive guide with sharp eyes makes the difference — critters are tiny and camouflaged.
- Sanctuaries charge a small diving / entrance fee collected by the municipality or barangay.
- Visibility and conditions change with the season; ask your guide the day before.
