Gunung Raung

Gunung Raung is a stratovolcano formed of andesite that rises 3,332 meters (10,932 feet) above sea level in Bondowoso, East Java. Its summit features a caldera about two kilometers (1.2 miles) wide and approximately 500 meters (1,640 feet) deep.

The first recorded eruption took place in 1586 and marked the beginning of a long series of volcanic events. Activity has continued across several centuries up to the present day.

Local Indonesian communities monitor the mountain conditions through traditional knowledge passed down through generations, supplementing modern volcanic observation methods.

The climb requires several days of preparation and experienced guides, as the routes pass through rough terrain. Access points are located around Bondowoso and near Sumber Wringin.

The summit caldera is among the largest dry craters in Java and one of the largest in Indonesia. Inside the caldera, small Strombolian eruptions occur regularly, keeping the interior of the crater in constant activity.
