In the north-eastern part of the country, near the border with Lithuania, between the cities of Suwałki and Augustów, there is a vast lake district especially popular with nature fans. In the unspoiled natural environment, they will find bewitching spots for picnicking. The capital of the region is the city Białystok. To the south of Białystok spreads the Białowieża Forest with the Białowieża National Park in its centre, renown as the last primeval forests in Europe. Three lakes surround Augustów, a local office organizes cruises. The Augustów Forest is one of Poland’s largest dense forest complexes. The 100 kilometre-kayaking trail runs through the forest along the Augustów Canal and River Czarna Hańcza.
