Nudi Falls should be high on the list when visiting Lembeh Strait. This dive site features a wall that drops from 1 to 20 meters, with rocky and dark grey sandy slopes and coral patches at around 28 meters. The gorgonians that adorn the wall in Nudi Falls are the place to find pygmy seahorses.

Nudibranchs, as the name suggests, are easily spotted in this area, but also cowries in different colors, scorpionfish, anemonefish, Banggai cardinalfish, and giant frogfish. Doing a night dive here is also recommended as striped eel catfish, black-saddled toby, wasp fish, painted frogfish, banded pipefish, boxfish, crocodile fish, cuttlefish, and octopus are putting on a spectacular show.

The currents can be strong in the deeper section of the dive site, especially around the rubble slope. It is important always to pay attention to the dive instructors.
