Ride to an uninhabited island and explore
Open: Late April through mid-November
You depart from the Lake Toya Onsen pier and ride to Nakajima Island on a tour ship. Register at the Nakajima-Mizuumi no Mori Museum, and start your walk! You might meet some deer along the way. Check the final departure times, and make sure to make it back to the docking area in time.
