Togean Islands dive sites

Una Una is a volcanic island that last erupted in 1983 in the remote Togean archipelago of central Sulawesi. The volcanic geology creates dramatic underwater walls and slopes that drop steeply into deep water. Because the Togean Islands are extremely difficult to reach, dive traffic is minimal, and the reefs around Una Una are among the most pristine in Indonesia. The combination of dramatic topography, exceptional coral health, and virtually no other divers creates a diving experience that feels truly exploratory.

The Togean Islands are one of Indonesia's most remote dive destinations. The typical route involves flying to Luwuk or Palu in Sulawesi, then taking a bus or car to the port town of Ampana, followed by a public ferry or chartered boat ride of 3 to 5 hours across the Tomini Gulf. There are a handful of basic eco-lodges on the islands, some with attached dive operations. The journey is long but rewards those who make the effort with uncrowded, pristine diving.

Una Una's last eruption was in 1983, and the volcano is monitored by Indonesian geological authorities. The island has been resettled and residents live on the lower slopes. Diving around the island is safe, and the volcanic geology is actually what creates the excellent diving conditions with steep walls and nutrient-rich waters. As with any active volcanic region, it is wise to check current status before visiting.
