The cone of Gunung Karang rises to 1,778 metres about ten kilometres northwest of Pandeglang town, the highest point in Banten. The forested upper slopes are protected and home to lutung monkeys, gibbons, and a long list of endemic birds.
A trail starts near the village of Kadu Bumbang and climbs in five to seven hours to the summit ridge, where on clear days you can see the Sunda Strait and the cone of Anak Krakatau. Pilgrim huts near the top are still used by Sundanese mystics who come for tirakat — overnight ritual visits.
