Nusa Penida is the largest (17km long) of 3 islands; the others being Nusa Lembongan and Nusa Ceningan that lie the other side of the Bandung Strait from Bali’s east coast. The water here is fairly cold, due to a cold upwelling from a deep ocean through south of Bali. But it is often startlingly clear, with gorgeous corals and prolific fish and some turtles, Grey reef and Silver-tip sharks. In Julyto mid-November, Mola-Mola, the weird and wonderful Ocean sunfish, can be seen here.
There are so many things to do in Nusa Penida. As the famous diving destination, there are some great diving locations in Nusa Penida Island, such as Penida Bay, Batu Meling, Batu Lumbung, Toyapakeh, Manta Point, Batu Abah and Malibu Point. The flow passing through the Lombok Strait is commonly heading to the south, while the tidal streams’ directions are commonly influenced by the seasons of monsoon.
Cold currents rising up from the deep allow for good visibility and preserve the coral reef. At times, these thermoclines are as cold as 16 ⁰ C, and encourage pelagic life to swim up from the deep where divers can catch a glimpse of some of these amazing fish. However, this island, due to its location between Bali and Lombok, is also exposed to very strong currents that arrive from the Pacific and move towards the Indian Ocean, which can generate very strong, sometimes violent, multidirectional current (including down-current). Due to the difficult conditions, we often reserve these dive sites for our more experienced divers or for those we have previously dived with and evaluated. Nevertheless, when conditions get too rough, there are always other protected dive sites waiting to be explored. So it’s a very good place for divers around the world.
