Founded in 1992, the Varniai Regional Park covers the highest part of the Žemaitija Upland. On the territory of the park, there is the highest hill of the Žemaitija, Medvėgalis (234 m above sea level) and the queen of the Lithuanian hills – Šatrija (228 m above sea level). Exclusive lakes also give the landscape of the Varniai Regional Park its uniqueness. One of them is Lūkstas - the only lake in Lithuania which washes out the amber on the shore and the largest natural lake in Žemaitija. Moreover, there are many wetlands with high biodiversity. The lakes and wetlands in the Varniai waterhole are one of the most valuable areas for birds in Lithuania. The Biržulis Botanical-Zoological Reserve with habitats of rare and endangered plant and animal species is distinguished for its ornithological value. It is a part of the European network of protected areas Natura 2000. Detailed information about the natural and cultural values of the park is available in the Varniai Regional Park Visitor Center.
