Gorontalo

General Info

Gorontalo is situated along the northern coastline of Tomini Bay in Northern Sulawesi, Indonesia. Tomini Bay reaches depths exceeding 4,000 meters, bringing deep ocean waters right up to the shore. Coastal currents push nutrient-rich waters toward the reefs, drawing deep-sea pelagic life close to the wall profiles—including schools of trevally, whales, and whale sharks. Pods of bottlenose dolphins and Risso's dolphins can also frequently be spotted in the area.

The coastline of Gorontalo is made of uplifted ancient coral limestone, naturally carved over time. The underwater topography is filled with crevices, swim-throughs, and caverns, alongside submerged pinnacles and sandy basins, creating one of the most breathtaking underwater landscapes in the world.

Located within the Coral Triangle—the global epicenter of marine biodiversity—Gorontalo is home to more than 500 species of reef-building hard corals, which is over ten times the variety found in the entire Caribbean.

Special creatures you will encounter while diving in Gorontalo include the Salvador Dali Sponge (Petrosia lignosa), a uniquely textured species not found in other famous Sulawesi dive destinations or oceans worldwide. It is also home to the Blue-belly Blenny (Ecsenius caeruliventris), an endemic species exclusive to Tomini Bay.

Another major highlight of diving in Gorontalo is the opportunity to see whale sharks at Botubarani, located just a 30-minute travel time away. The highest chance of whale shark encounters occurs between March and July, when they regularly visit the area.
