It takes about 30-45 minutes to hike up to the Onigashima Cave. Alternatively, you can take a bus from the ferry terminal to the cave in about 10 minutes. The bus costs 500 yen one way or 800 yen for a round trip. Buses run when the ferries arrive, but they don’t operate every day during the off-season.

Onigashima Cave (鬼ヶ島大洞窟), located on Megijima Island, is a must-visit for adventure seekers.

The cave is easily accessible via a short ferry ride from Takamatsu, followed by a bus or bike ride up the mountain. For a more leisurely visit, you can rent a bike or take a bus for a smooth ride.
