Diving Crystal Bay, Nusa Penida

Crystal Bay dive site and the Mola Mola

Crystal Bay dive site is one of the most famous dive sites in Bali and even in Indonesia. Diving Nusa Penida without diving Crystal Bay would be like going to Paris and not seeing the Eiffel Tower. It is indeed one of the few places in the world where you can meet the Mola Mola very regularly, between July and October. And some years even earlier.

The Mola Mola, or oceanic sunfish, has the particularity to grow until the end of its life. It can reach 3 to 4 meters in diameter and weigh more than one ton. It will come up from very deep following the upwellings that bring with them nutrients. The upwelling is a phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water.

When diving Crystal Bay, your best chance to meet the Mola Mola is after what is called the second corner, behind the small island in the middle of Crystal Bay. But you must be very attentive to tearing or down currents that can be violent. It is therefore essential to follow an experienced guide knowing perfectly well the dive site and to respect his instructions.

Crystal Bay, an aquarium in Nusa Penida

Even when it is not the season for Mola Mola, Crystal Bay is a great dive spot. It consists of 2 distinct parts. The left part and the right part are separated by a band of sand that goes down to 30 to 40 meters. It continues to the middle of the channel that separates Nusa Penida island from Nusa Ceningan and Nusa Lembongan islands.

The left side of the site (to the southwest) is an ideal coral plateau for discovery dives. You can admire a lot of colors, a lot of diversity of coral and fish. It is a beautiful dive site to discover with a shallow depth that meets the criteria of PADI standards.

The right part of the site (towards the islet in the middle of the bay) is the starting point to go and search for the Mola Mola.

Crystal Bay is also a great snorkeling spot in Nusa Penida island and it is worth to pay a visit to the beach after the dive. After the beach you can also go to Amok sunset to have a drink, eat some nice food and rest around the pool before the sunset.

Diving Crystal Bay

Crystal Bay dive site is very wide and there are many ways to dive here. An excursion to Crystal Bay is never the same experience twice. We start our dive on the coral plateau that surrounds the bay’s emblematic rock. Then, the call of the blue will bring us on coral bumps and asperities, which are typical for this dive spot. From there you can admire the site’s breathtaking piece of aquatic art. The slope goes deeper down and into a white sandbar. On your way back, some canyons, digged into the rock, are home for many different species.

We can also go around the rock, in the direction of the wall, which is full of color and life, and hit by the currents.

Crystal Bay is a massive playground for divers but also for animals. It’s the favorite dive spot of the Mola Mola, moray eel, leaf fish. At Crystal Bay you can find everything.

The Crystal Bay Wildlife

Crystal Bay dive site offers the opportunity to see a wide variety of corals and fish such as surgeon fish, butterfly fish, rabbit fish and sergeant fish.

We may also meet moray eels including the very cute and small moray ribbon. You can see regularly turtles, and sometimes even bamboo sharks and manta rays. Macro lovers will not be disappointed either. They may see Zanzibar shrimps, Thor shrimps, porcelain crabs and many varieties of nudibranchs.

The two corners of Crystal Bay dive site

There are many ways to enjoy scuba diving at Crystal Bay dive site. A very simple route, for less experienced divers, is to leave the boat at the left of the islet located in the middle of the bay. Then stay a little bit on the plateau and reach by a gentle slope what is called the first corner. This corner is the first rock of the island that forms an angle and protects the bay from the current. Without exceeding the first corner, the dive ends by returning to the protected part of the bay.

The canyons

More confirmed divers, with the good guide, will go beyond the first corner. The slope becomes like a spine of coral that sinks very deeply. Currents can be strong which is the opportunity to see big trevallies and a very colorful coral vegetation.

Going up the slope on the right leads you to three canyons. There is often surf but the canyons are still very preserved because few divers go there. They are very rich in macro, there are beautiful colors and you can observe very beautiful fish in small groups.

The famous second corner

Continuing along the wall, without going up to the canyons, you will reach what is called the second corner. This is where we can most often see the Mola Mola, in the blue. But the currents can be very violent and it is imperative to follow an experienced guide.

In general, we go back to the right side of the coral reef which goes back to the Crystal Bay island. And we finish the dive sheltered from the currents, in the bay.
