Gunung Halimun, Stratovolcano in West Java and Banten, Indonesia

Gunung Halimun is a Pleistocene stratovolcano on the border of Banten and West Java, in the Bandung Zone volcanic belt. Its summit, North Halimun, reaches 1,929 metres with a prominence of 938 metres. The photograph shows no crater or rock face: dense deep-green forest with rounded crowns covers the rising ground, thin pale trunks rise through the canopy, and white mist drifts across the lower slope and between the crowns.

Gunung Halimun is a Pleistocene stratovolcano in the Bandung volcanic belt, on the border between Banten and West Java. Its northern summit, North Halimun, reaches 1,929 metres with a prominence of 938 metres, making it the highest point in Banten Province. The name Halimun is Sundanese for "foggy" or "misty" and is shared by two peaks in the national park, though it usually refers to the higher northern one.

Halimun is Sundanese for "foggy" or "misty". The name is given to two peaks in the national park, but is commonly applied to the higher north peak, the 1,929-metre summit. The forest on the mountain is almost always enclosed in cloud, so the name describes what walkers actually meet.

A permit from the Mount Halimun Salak National Park authorities is required before entering. The route from Leuwijamang village, north of the mountain at 800 metres, takes about eight hours up and back, but the park does not recognise it as an official climbing lane, so climbing is not allowed.

The forest on Gunung Halimun is almost always wrapped in cloud, which is how the mountain got its name: halimun means "foggy" or "misty" in Sundanese. The name is shared by two peaks in the national park, but it is usually applied to the higher north summit, North Halimun, at 1,929 metres.
