Nusa Menjangan (Menjangan Island) a 1.5 km long and 500 m wide island in the north/west Bali national park.

Except in the western part of the island, coral growth starts in shallow water, stretching out for about 20 to 30 metres before suddenly dropping vertically to a depth of 30 metres. The western end features a deep lagoon with a reef slope in a 45-degree angle. Currents at Nusa Menjangan are weak to moderate with the strongest currents present at the western lagoon. Therefore Menjangan is a perfect spot for beginners. Because of the beautifully grown lagoon, it is also an outstanding spot for snorkelling.

Menjangan's underwater world surely deserves to be listed as one of the world's top dive sites; coral counts have shown that this small island alone features more coral species than the whole Caribbean! It is quite simple packed with all manner of soft and hard coral, sponges and gorgonians covered in feeding feather stars.

Quite often you will encounter Napoleon fish, turtles, bumphead parrotfish and groupers. In deeper water you may see white and black tip reef sharks and some large barracuda. Lucky divers will find eagle rays, sunfish and even whale sharks if the season is right. Lots of small but interesting creatures are permanent residents and ther3e is simply too much marine life to list in this limited space in case the big guys are 'having a day off'!
