Things to do: 
At the heart of Izu Oshima is the 758 meter tall Mount Mihara, an active volcano which is the source of several interesting sites and various hot springs on the island. Beaches at the island’s northern and western coasts are the venue for snorkeling, sunbathing and other beach activities during summer.
