Narew National Park: Narew is a unique river. Between Suraż and Rzędziany, it does not flow in one channel but several which merge and branch. The arms of the Narew River form a real water maze. Such rivers are called anastomosing, i.e. multi-channel. This unique section of the Narew, called the “Polish Amazonia”,” is protected by the Narew National Park. Due to the multi-channel system, the valley is wet all year round, and during spring thaw, a large part of it disappears under water. In combination with the lush rush vegetation (reeds, sedges, reed maces, etc.), this makes the Park difficult to access. Thanks to this, it has become an important refuge for animals. Among about 200 species of birds found here, over 150 are breeding ones, including some endangered and many rare species. An interesting fact is that the Narew National Park is one of the least forested of all Polish national parks. It is dominated by open areas – reed rushes and sedges. The best way to visit the park is by water, canoeing. Another possibility is the use of educational footbridges which allow you to reach places inaccessible by other means.

Wigry National Park: is distinguished by an extraordinary wealth of lakes surrounded by vast forests. In addition to the largest and most picturesque Lake Wigry, the park contains 41 other natural water bodies. A unique feature of the park is the presence of suchary—small, dystrophic forest lakes with acidic water rich in humic substances, surrounded by a floating mat primarily composed of sphagnum mosses. The Czarna Hańcza River, a tributary of the Neman, flows through the park. In the northern part of the park, fast-flowing rivers such as the Kamionka, Wiatrołuża, and Maniówka can be found. It is safe to say that no other national park in Poland has such a well-developed and diverse lake district landscape shaped by the most recent glaciation. This forest-and-lake landscape is complemented by open areas of villages, fields, and meadows, featuring a varied post-glacial terrain. In many places, breathtaking views open up to the former Camaldolese monastery complex, majestically rising on the Wigry Peninsula.
