Kaunas Reservoir Regional Park was established in 1992 with the purpose to protect the unique lower landscape of Kaunas Reservoir, its natural ecosystem, and cultural heritage. It covers the total of 101.73 km² and is one of the 30 regional parks in Lithuania.
The man-made Kaunas Reservoir altered the local landscape and now one can see newly formed exposures, altered mouths of tributaries to the Neman River. The shallower edges of the reservoir are becoming swampy and attract almost all known species of water birds in Lithuania. Old pine forests at Rumšiškės and Dabinta are rich in plant animal diversity. Here lives one of the biggest population of edible dormouses.
