Kauno Marios Regional Park was established in 1992 with the purpose to protect the unique lower landscape of Kaunas Reservoir, its natural ecosystem, and cultural heritage.

The shallower edges of the reservoir are becoming swampy and attract almost all known species of water birds in Lithuania.

Since 1963 a tradition among Kaunas Forestry college graduates has been established: every year students plant the oak in this grove.

Cultural heritage objects include Pažaislis monastery, a 17th-century baroque architecture masterpiece which hosts an annual Pažaislis Music Festival, open-air museum in Rumšiškės covering 175 ha, Salomėja Nėris museum in Palemonas which hosts annual Poetry Spring.

Pakalniškiai, Vieškūnai, Lašiniai, Samylai, Dovainoniai hillforts and Dovainoniai/Kapitoniškiai, Maisiejūnai/Surgantiškiai tumulusses are located in the park.
