To dive Menjangan Island, we would have to travel to West Bali National Park, which is a 3-hours car ride from Sanur. Arriving at the port, we would then sail 30 minutes by boat. This island can be dived year-round and by all levels of divers, as it offers some of the most protected and safe diving spots in Bali.
Currents over than 1 knot are unusual, with visibility around 15-30 meters. Menjangan dive sites are actually famous for its walls, descending to various depths, the shallowest being 26m, the deepest 60+m. The walls offer the greatest diversity of gorgonian fans in Bali, generally starting at 10m with flat reefs offering gentle conditions and lots of sunlight. These areas are full of small to medium size fishes. The walls are full of small nooks and crannies, overhangs, bigger cavelettes and crevasses, covered with soft corals, gorgonian fans, and sponges. Ironically, although providing relatively safe diving conditions, Menjangan Island also has the highest rate of decompression sickness due to the deep diving. Thus, remember to always stay safe.
Dive Spots around Menjangan Island
Post I is a vast dive site, covering more than 60.000 m2 underwater life, partial drop-offs, slopes and flat areas. Generally visibility is over 20m. You can expect to be accompanied by some friendly Bat Fish through out your dive. The Jetty seafloor is also excellent for training.
Located on Menjangan’s most southeasterly point, Post II can be accessed by both beach or boat-entry. Dives start at 12m, where the white sand slope meets the top of the wall. Dive along the wall and see the dense life that covers it. From here, you can go back to the entry point where boat will be waiting, or have the boat to pick you up at the exit point. Under 25m, the current will take us along the wall to the east point of the island, decorated with large gorgonians. Here, the water travels down, meeting an upwelling of cold water, which brings with it turtles, Manta Rays, sharks, occasional Mola-Mola and other pelagics. Our safety stop will be done above the remaining coral reef (8-12m). As there is quite a population of Titan Triggerfish in the area, we need to choose our spot carefully.
Bat cave point
This site is probably the best dive spot at Menjangan. Bat cave point is filled with many gorgonian sea fans, sponges and the most beautiful corals in the whole island ranging between 3 to 40m deep. At the depth of about 9 until 12m, the caves are hidden into the reef walls. The rich corals within an interesting landscape are an underwater-photographer’s playground. In addition, this is a great dive spot for all diving levels. Because it’s located in the East South corner of the island, current can flow in from the East and hit this corner head on, bringing in a great number of schooling fishes, looking for a higher concentration of plankton. As smaller fishes attract bigger fish, expect to see Blue fin trevallies, Big-eye trevallies and the occasional black tip reef sharks. Normally, this is where you can expect currents, but nothing to be worried about. Just follow the current.
Garden eels is located in the north-western tip of Menjangan Island. Descend north west and head to south, gradually following the wall down from the top 5 meters to 25 meters (max 35 meters). The wall becomes a white sand slope, where you'll find a big gorgonian fan with its residential long-nose hawkfish. This area is also known for sightings of white tip reef sharks, small schools of barracudas, turtles, and of course Napoleonfish. From this 25-meter point, we ascend slowly reaching a huge colony of garden eels, which covers the slope from 20m and flattens out at 14m. From Garden Eel Point we head south to a coral garden at 5-12m. This area is home to Big-Eyed Trevallies, Titan Triggerfishes, many clown fishes in their anemones and often a surprisingly number of scorpionfishes. Surprise!
To reach Menjangan, we have to go to West Bali National Park which is 3 hours car ride from Sanur, then 30 minutes by boat. This island can be dived year-round and by all levels of divers as it offers some of the most protected diving in Bali.

But due to the deep diving around the island, Menjangan has the highest rate of decompression sickness compared any other dive sites in Bali, so stay safe.
