Narew National Park (Polish: Narwiański Park Narodowy) is a National Park in Podlaskie Voivodeship, north-eastern Poland, created in 1996. The park is a 35 kilometres (22 mi) section of the Narew River. It is a swampy valley with moraine hills typical of a braided river. Depending on the season and the level of the water table, several riparian area ecosystems are available including swamps, tussocks with surrounding Black Alder (Latin: Alnus glutinosa) and White Willow (Latin: Salix alba) forested areas.
