Behind the village of Prilozje there are three ponds that are connected to each other. Today the central and eastern ponds are used for breeding fish, mostly carp, tench, crucian carp, common bream, etc. The west pond is left to its own natural processes and represents an important natural habitat for many endangered and rare species.

The ponds used to belong to lordship in Gradac castle and were mentioned as early as 1824. The wetlands are a quiet area where observations of birds, pond turtles, dragonflies, and other animals can be held. The pond turtle is of particular interest because it is on the endangered species list and is the only autochthonous turtle in Slovenia. Because of the pond turtle's endangered status, all the ponds are included in the Natura 2000, the European network for protected areas. The pond is owned by the Fishing society of Metlika. Fishing is available from the end of May to September. The area is also accessible to persons with disabilities. There is a path leading around the pond.
