Nudi Falls is one of the best known sites at Lembeh Strait.
One of the three most-dived sites (along with Nudi Retreat & Hairball), a colourful sheer miniwall with a rock pile below, then a sand slope, leveling out into the main channel of rubble sprouting a forest of large soft Corals. Scenically this site is unlike any other in the strait. From the surface down to about 10m the is a wall which is covered with corals and lots of hydroids. On this wall you can also find many nudibrach if you dive there at the right time of the year. The deeper parts of the site has black sand ground with some coral blocks and there is a beautiful soft coral field on 23m.
There is a whole range of attractions here: sightings of rare Eschmeyer's Scorpionfish (Rhinopias eschmeyeri), Harlequin Shrimp and Boxer Crab happen regularly. Robust Ghost Pipefishes, Wonderpuses and other muck critters are found on the sand slope. Frogfishes, Pygmy Seahorses, Ornate Ghost Pipefishes, Batfishes, Comet fishes, File Shells (Ctenoides ales) and Peacock Mantis Shrimps are commonly sighted near, in or on the wall along with Nudibranchs.
This is usually the most Nudibranch-rich site in the strait and along with Jahir, it is the most popular night-diving destination.O
