Embung Nglanggeran, Artificial reservoir in Nglanggeran, Indonesia

Embung Nglanggeran is an artificial pond on Bukit Gandu in Nglanggeran, Patuk, Gunung Kidul, Yogyakarta. It was built to hold rainwater for irrigating farmers' fruit plantations during the dry season. The pond lies on the slopes of an ancient volcano, surrounded by orchards planted by local residents, and its elevated position gives views over the surrounding land.

The reservoir was built on Bukit Gandu by the government to hold water for farmers below, who use it to irrigate their fruit plantations during the dry season. Sri Sultan Hamengkubuwono X inaugurated it on 19 February 2013.

Local farmers manage fruit orchards around the water body, growing durian, longan, rambutan, avocado, and cocoa across the surrounding slopes. This farming tradition shapes how people in the area live and use the land around the reservoir.

Parking areas, restrooms, prayer facilities, and food stalls are available on the grounds, along with several viewing towers for exploring the site. Visitors should expect some walking on inclines and should arrive early to enjoy clear views.

The water displays a natural turquoise-green color in daylight due to algae growth at the bottom of the basin. This color shift changes throughout the day depending on the sun angle and weather conditions.
