The name 'Sikidang' is derived from the Javanese word 'kidang,' meaning deer, due to the crater's historical tendency to 'leap' or shift locations within the caldera.
The landscape features bubbling mud pots caused by high-temperature geothermal gases escaping through groundwater.
The sulfur deposits around the crater are a result of volcanic gas interacting with the surface environment.
The site is part of the broader Dieng Volcanic Complex, which contains several other distinct craters and lakes.
Sikidang Crater is an active volcanic vent characterized by its shifting crater floor, which migrates within a designated area every few years. The site features a main geothermal pool that bubbles aggressively and releases visible white plumes of sulfuric steam. Visitors walk along a wooden boardwalk that encircles the primary vent to provide proximity to the volcanic activity. The soil in the surrounding area is yellowish-white due to high sulfur content and mineral deposits. As of mid-2026, the area remains a primary geothermal tourist destination in the Dieng Plateau. The crater is situated at an elevation of approximately 2,000 meters above sea level, contributing to a consistently cool climate.

Wear a face mask to mitigate the strong sulfur odor if you have sensitivities to pungent gases.
Bring a jacket as the high altitude and geothermal winds result in significant temperature drops.
Stay strictly on the designated boardwalks to avoid soft, unstable, or scalding ground.
Do not wander off the boardwalks into the active steam fields, as the ground can be unstable and thermally hazardous.
Avoid touching the steam vents or throwing objects into the mud pools; exercise caution regarding the slippery wooden surfaces.
