The site is a key component of the Gunung Sewu UNESCO Global Geopark network.
The lake occupies a high-altitude position, requiring a moderate hike from the base parking facility.
Embung Nglanggeran is a man-made irrigation reservoir situated on the slopes of the Nglanggeran Ancient Volcano in Gunungkidul, Yogyakarta. The lake serves as a water source for local durian and cocoa plantations in the surrounding highlands. It is located at an elevation of approximately 400 meters above sea level, offering panoramic views of the karst landscape and nearby village fields. The site was constructed to prevent soil erosion and manage water distribution for local farmers. It is part of the broader Nglanggeran Tourism Village area, which is recognized as a UNESCO Global Geopark. The reservoir is surrounded by rocky cliffs and volcanic boulders characteristic of the area's geological history. Visitors reach the lake via a paved inclined path from the parking area. The site is primarily used for recreational sightseeing and agricultural water management.
