About Gili Selang
Gili Selang is a small island located off Bali's easternmost tip, forming a striking geological feature at the foot of Mount Seraya. Its strategic position means it receives the full force of the Indonesian Throughflow, making it a dynamic and often challenging dive site that offers a unique blend of marine ecosystems. Divings here typically begin on a black sand slope, rich with macro life such as nudibranchs and gobies, before transitioning into a vibrant, sheltered reef at around 4 meters. This reef boasts a diverse array of colorful soft and hard corals, including impressively large Acropora table corals and extensive soft coral fields. Further offshore, the environment shifts to a more exposed, pelagic realm, characterized by steep slopes that can drop dramatically to depths exceeding 200 meters just 100 meters east of the islet. The site is renowned for its diverse marine encounters, ranging from macro critters like pygmy seahorses on gorgonian fans to larger pelagic species. Divers frequently spot schooling big-eyed trevally, yellow margin morays, and cuttlefish, while sharks, including blacktip, whitetip, and grey reef sharks, are common. During the right season, you might also encounter hammerhead sharks, tuna, mackerel, and even mola mola. Sea snakes are regularly observed, a rare sight in nearby areas. Due to the variable and strong currents, Gili Selang is primarily suited for experienced divers. Most dives here are drift dives, leveraging the powerful currents. Divers must pay close attention to briefings and stay near their guide due to unpredictable changes in conditions. It’s often dived by boat, departing from locations like Tulamben, and may involve riding out strong currents, sometimes referred to as the 'Selang Express'.

Conditions & Currents
Gili Selang is notorious for its powerful and often unpredictable currents, including up, down, and swirling flows, which can be immensely strong. The site experiences the full brunt of the Indonesian Throughflow, and currents can shift rapidly, sometimes accompanied by an audible boom underwater. A negative entry may be necessary, and dives are typically planned as drift dives, with dive guides using local knowledge and tide charts to manage safety. Visibility here is generally excellent, often reaching 20-25 meters, but thermoclines are common, causing water temperatures to fluctuate between 20-30°C. Due to the severe and complex current patterns, including the 'Selang Express' that can carry divers rapidly, this site is strictly recommended for experienced, advanced divers with drift diving proficiency. Divers must remain close to their guide and understand that being caught in the strongest currents means riding them out.
Why dive Gili Selang from a liveaboard?
Gili Selang is one of Bali's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
