Nudi Falls
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
Nudi Falls compresses several Lembeh habitats into one small site: a miniature wall hung with pink soft corals, a cascade of rubble, and the obligatory dark sand below. The name delivers, with nudibranchs in a density and variety that turns even non-photographers into inventory clerks, but the wall also hides Pontohi pygmy seahorses, blue-ringed octopus on patrol, and ghost pipefish drifting beside crinoids. A resident rhinopias, when one is in office, becomes the strait's most photographed fish. Because the terrain is layered, guides can run the dive shallow and long, and the soft-coral backdrop gives Lembeh's rare chance at pretty wide-angle without leaving the muck.
The moment you come for: Nudibranch variety; pygmy seahorses and blue-ringed octopus; soft-coral wall backdrops.
Topography: A short rock wall draped in soft coral spilling onto a rubble-and-sand slope.
Know before you splash
Hazards: The usual venomous suspects plus fire urchins on the slope; buoyancy over the rubble protects the small stuff.

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
