The Pinnacle is one of the best diving sites all over the Togian Islands. Located on the east side of the Una-Una Island and rarely visited by divers, the walls in this dive site drop off to 60 meters, decorated with various species and colors of sponges, from black, gold, and green tube sponges to vase, cone, and barrel sponges. Hard corals, sheet corals, and Acropora are also abundant here.

Lantern toby, longnose emperors, sweetlips, snappers, fusiliers, and crocodile long toms roam freely in large groups in this region, giving the impression of a crowded aquarium in a good way. Other fish species like gobies, triggerfish, bumphead parrotfish, butterflyfish, angelfish, and anemonefish add to the already colorful scenery in The Pinnacles. Turtles and eagle rays also frequently visit this region.
