To peer into a live, sometimes smoldering volcano, join one of the popular excursions to Nea Kameni, the larger of the two Burnt isles. After disembarking, you hike 430 feet to the top and walk around the edge of the crater, wondering if the volcano is ready for its fifth eruption during the last hundred years—after all, the last was in 1956. Some tours continue on to the island of Therassia, where there is a village. Many operators on the island offer volcano tours.
