Hiking and camping in the mountains are popular adventure activities. Some mountains contain ridge rivers, offering rafting activity. Though volcanic mountains can be dangerous, they have become major tourist destinations. Several tourists have died on the slopes of Mount Rinjani, Indonesia's second-highest volcano and a popular destination for climbers visiting Lombok in eastern Indonesia. Popular active volcanoes are the high Mount Bromo in the East Java province with its scenic volcanic desert around the crater, the upturned boat shaped Tangkuban Perahu and the volcanic crater Kawah Putih, north and south of Bandung respectively and both with drive-in access up to the crater, the most active volcano in Java, Mount Merapi near Yogyakarta, and the legendary Krakatau with its new caldera known as Anak Krakatau (the child of Krakatau). Gede Pangrango volcano in West Java is also a popular hiking destination, especially among domestic hikers.
