Jandri Scuba Dive Lembeh is a locally owned dive operator in Bitung, North Sulawesi, running daily guided muck diving in the Lembeh Strait. Local guides lead boat dives across the strait's black-sand slopes, including well-known critter sites such as Nudi Falls and Hairball.

Local guiding matters in Lembeh more than almost anywhere: the diving is about finding camouflaged animals like frogfish, mimic octopus and rare nudibranchs, and guides who dive these slopes every day find what visitors would swim straight past. The center holds a 5.0 Google rating from nearly 50 reviews.
