Pasir Tengah, literally translated as Central Sands, is one of the best diving spots in Togian. It is a 3-kilometer-wide coral atoll with vertical walls descending into the depths of 400 meters from the surface.
The steep walls are covered in different species of corals, from red and green tube sponges, barrel sponges, gorgonians, leather corals, leaf corals, and black corals, among others. Going deeper, packs of trevallies (big eye, six banded, yellowfin, and bluefin), midnight snappers, tunas, fusiliers, and butterflyfish move gracefully in all directions.
Eagle rays and reef sharks like whitetip and blacktip can also be found close to the reef, and sometimes silky sharks can be seen patrolling the area.
