Lisina Lake is an artificial reservoir on the Lisina River, tucked between Bosilegrad and Božica in southern Serbia. It's an unusual stop for travelers curious about how mountain water systems work, offering a quiet, industrial-meets-nature landscape rarely found on typical tourist maps.

Built in 1978 as part of a pump-storage hydroelectric facility, the lake serves as a secondary reservoir for the larger Vlasina Lake. Two powerful pumps lift water from Lisina up 340 meters, sending it through a network of channels - including the Božica canal with its two tunnels - into Vlasina Lake above. Each year, roughly 74.7 million cubic meters of water make this journey. The surrounding terrain is calm and remote, with rolling hills and a sense of untouched wilderness that appeals to visitors seeking solitude rather than crowds.

• From Bosilegrad - via local road toward Božica, moderate route
• From Božica - shorter approach via local roads

• The site is part of an active hydroelectric infrastructure, so access to technical facilities may be restricted

It's one of the few places where you can witness firsthand how a pump-storage system channels water hundreds of meters uphill to feed a much larger lake.
