Mount Wilis

Mount Wilis is a volcano in East Java that stands isolated above surrounding lowland plains and reaches about 2,563 meters in height. Its flanks show clear erosion patterns, while the summit area is covered with dense forest and displays gentle slopes.

The volcano formed during the mid-Pleistocene and developed its youngest cone during the Holocene, changing through several phases of volcanic activity. Historical records document no eruptions, suggesting a long period of rest.

Local communities in East Java have established settlements around Mount Wilis, with over 500 people residing within a 5-kilometer radius of the volcano.

Hiking trails lead to the summit from several starting points in East Java, with early morning hours offering cooler temperatures and better visibility. The ascent takes several hours and requires physical preparation and sturdy footwear for steep sections.

Fumaroles and mud pots remain active on the western flank near Lake Ngebel, showing ongoing geothermal activity beneath the surface. These features can be observed when visiting the lakeside area, where the ground stays warm in places.
