Climbing route
The trailhead for the Mount Rebun hike is in Nairo. It is a 3-hour hike with no water available. The trail first passes through fields of sasa-no-ha before entering a forest of pine and birch. The peak rises above the forest to grant an unobstructed view of the entire island.{{cite book|last=Bisignani|first=J.
