More ways to explore the area's outdoor wonders
Pre-dawn on East Java feels like a held breath as vans slip away from Banyuwangi and into black ridgelines. At Paltuding, hikers step onto a volcanic track that climbs through pine stands and loose ash toward the crater rim. The hike is mostly uphill and the trail narrows as the sulfurous wind begins to bite; guides lead small groups toward the blue flames that sometimes lick out of fumaroles below the rim.
