Perucac features what is reputedly Serbia's smallest river — River Vrelo. This is known as the "One-year-long River", due to its length— 365 m— from its source to its end, with the length in meters corresponding to the number of days in a year. Vrelo flows into Drina just a few hundred meters below the artificial lake. On this small river is built a beautiful restaurant.
