Why it matters
- • Rare chance to trek an active volcano crater.
- • Best diving in the Togeans with healthy reefs.
- • Raw, authentic island experience.
Mount Colo volcano trek
Hike the 500-meter volcano to reach the 2km-wide caldera formed by the 1983 eruption. The crater floor is covered in vegetation, volcanic steam vents still release heat, and views stretch across the entire archipelago. The trail climbs through coconut groves growing in fertile volcanic soil.

World-class dive sites
Sites like Apollo, Pinnacle, and Menara offer 30-40 meter visibility with massive corals, giant sponges, barracuda schools, trevally, reef sharks, and turtles. Volcanic nutrients from the 1983 eruption have enriched the reefs, creating exceptional coral health and fish density unmatched elsewhere in the Togeans.

Eastern coastline villages
Fewer than 2,000 residents live in villages clustered along the eastern coast where black volcanic sand meets the water. Mosques, small ports, houses rebuilt after the 1983 eruption, and paths winding through coconut groves. No roads connect settlements — movement is by foot along coastal trails or by boat.
