Crystal Bay

The "Crystal" of Crystal Bay refers to the fantastic visibility of this scuba diving and snorkeling site in Nusa Penida, which can reach 40m on a good day.

Crystal Bay is one of the most famous places in Bali because it is one of the only places in the world where you can meet the giant sunfish (called "mola-mola") of about 3 meters in wingspan. The strange mola mola looks like a big swimming head without a body. It is the heaviest bony fish known in the world, it can weigh up to 1000 kg.

From June to mid-November, these pelagic come up from great depths to be cleaned by the cochin fish and angelfish which await them between 25 and 40 meters.

The water is often cold with temperatures of around twenty degrees Celsius, even dropping to 16 ° C! We recommend that you dive here in a 5mm wetsuit (our dive center can provide you with one). Water temperatures are lowest from June to October and highest from November to February.

The bottom of the bay is covered with golden sand and is surrounded by sloping coral reefs on either side.
Outside of the mola-molas season, the diving remains excellent. The site is very rich in coral and reef fish (clown fish, oriental sweetlips, anthas, angelfish triggerfish, cochin fish ...).
It is not uncommon to come across wobbegong, turtles, trevally, and of course macro life as on all the sites of Nusa Penida.
