The Wigry National Park (Polish: Wigierski Park Narodowy) east of Olecko, in the Podlaskie Voivodeship, is particularly known for its crystal-clear lakes.
The (as of 2008) 15,086 hectare protected area between the cities of Suwałki and Augustów was established in 1989. The 25 largest lakes in the park, of which the large lake Wigry is the showpiece of the park, are all connected by waterways. The main tributary of Lake Wigry is the Czarna Hańcza river. There are also some swamp lakes in the park. The national park, with its peat bogs and meadows and extensive pine and spruce forests, is home to more than 750 plant species and 1,500 animal species, including moose, wolves and beavers; The diversity of water birds is particularly noteworthy.
The park directorate is located in the village of Krzywe, near Suwałki. In addition to visitor information, there is also a natural science museum with information about the park and its fauna/flora as well as an ethnographic museum. In addition to the rolling hills (especially in the north of the area) and the beautiful lakes, which are very visitor-friendly thanks to the connecting waterways, the regional features of the park also include the former Camaldolese monastery in Wigry.
The monastery has been rented to the Polish state since 1973, which renovated it and expanded it into a cultural center with exhibitions of modern art, concerts and workshops. Source: Wikipedia
