Batu bolong is a seamount emerging to the surface in the middle of the Lintah Strait. Depending on the tide you can either dive the south or the north side.
Swim past steep rocks, canyons and coral blocks in clouds of damsels, surgeonfish and triggerfish. Many different nudibranch, shrimps and other small critters are hiding in the corals. But also bigger fish can be spotted here: giant sweetlips, napoleon wrasse and rainbow runners cruise by. While turtles swim up for a breath of fresh air you gaze at the giant trevallies and dogtooth tuna at the side of the seamount enjoying the current.
Situated along the eastern side of Komodo Island, Makassar Reef is a series of sand banks that stretch 3km long and offers one of the best opportunities to see Manta Rays in the National Park. Many small coral bommies and patches of reef are home to cleaner wrasse and butterflyfish which function as cleaning stations for these huge gentle creatures. But it is not only mantas that can be seen here: due to the strong currents in the Lintah Strait, reef sharks are often seen in this area along with turtles and giant trevallies.
Castle Rock is situated in the north near the island of Gili Lawa Laut and can be one of the most exhilirating dives in Komodo National Park due to the strong currents that often flow through and around the site. As a submerged seamount, it offers a great variety of sea life, from pelagics to reef fish to macro critters.
Depending on the conditions and your level of experience, it can be dived in strong or mild currents. When the current is stronger, you may find white tip sharks and even grey reef sharks patrolling the depths as well as trevallies and huge schools of fusiliers. Diving around slack tide will allow you to really explore the whole site where you may come across feeding turtles, shy juvenile white tip sharks and even a pygmy seahorse.
This is another seamount close to Castle Rock that breaks the surface during low tide. It is a beautiful site for both coral and fish life. Schools of trevally and fusiliers, dogtooth tuna, spanish mackerel, napoleon wrasse and reef sharks can be seen upcurrent. The pinnacles are covered in soft corals of all colours and on the plateau to the west are huge table corals. Often spotted here are sweetlips and schools of snapper as well as the occasional crocodile fish. Finishing the dive on the main pinnacle not only gives protection from the current but is also a great place to look for scorpionfish and octopus.
The Cauldron is the narrow passage between Gili Lawa Laut and Gili Lawa Darat and best dived on a falling current. A thrilling drift dive, you begin in the shallows over white sand and coral bommies until you reach the impressive 24m deep cauldron. On the norths side you look up from a mini-cave to see giant trevally and snappers hanging in the current. On the south side of the cauldron is a huge wall decorated with fans, soft coral and sponges. Getting shot out of the cauldron onto a shallow plateau is a highlight of the dive. Drifting on the plateau you can encounter manta rays, eagles rays, sharks and humphead parrotfish. You finish the dive on a beautiful soft coral garden scattered with gorgonian fans and feeding turtles.
Mawan is, next to Manta point, the best place to spot mantas. The north side of the island has a beautiful shallow plateau covered in hard coral and barrel sponges. On the east side we find several cleaning stations in shallow waters where the mantas like to come and get cleaned by butterflyfish and cleaner wrasses. The soft coral on Mawan is absolutely stunning with many different kind of anemones giving shelter to a variety of clownfishes. Do have a closer look on the sandy slope where flounders like to hide and little nudis are about.
