Eco Divers Lembeh is a PADI 5 Star dive resort on a white sand beach in the Lembeh Strait, set up for underwater photographers and macro divers. It has run since 2002.

It has critter spotting guides, private boats, a camera room with charging stations and air blowers, and instruction in English, Indonesian, Italian and French.

Diving here means muck: slow searches over black volcanic sand for frogfish, mimic octopus, flamboyant cuttlefish, pygmy seahorses and rare nudibranchs. Many guides rate July to November as the peak critter months.
