Ring of fire is a reef-and-wall dive in the Togean Islands that pairs a dramatic vertical face with a gentler coral slope. A typical swim tracks the wall before easing out onto the sloping reef, giving both wide-angle scenery and close-up critter hunting. The site is known for colorful nudibranchs, shrimp, and crabs, with the occasional blacktip reef shark or eagle ray passing through. Because the wall drops away quickly, plan your dive to manage depth changes and stay aware of open water.
