The path crosses the unique 'quaking bog' formation, where a thick layer of vegetation floats over deep, waterlogged peat.
It is one of the few places in Poland where the endangered European pond turtle (Emys orbicularis) can be observed in the wild.
The trail features sundew (Drosera), a rare carnivorous plant that thrives in the nutrient-poor acidic peat soils of the reserve.
The boardwalk system was engineered specifically to prevent human disruption of the delicate, water-saturated moss layers.
The path leads to Lake Moszne, a dystrophic lake characterized by dark, humic acid-rich water and a lack of shoreline vegetation transition.
Nature trail Spławy is a 7.5-kilometer wooden boardwalk path located within the Polesie National Park in eastern Poland. The trail traverses diverse ecosystems, including transitional bogs, peatlands, and alder forests, which are characteristic of the Polesie region. A significant portion of the route is elevated above wet, marshy ground to protect sensitive wetland flora while allowing pedestrian access. Visitors encounter a variety of habitats, including Lake Moszne, which features a distinct quaking bog with rare vegetation. The trail is equipped with observation towers that provide vantage points for birdwatching and surveying the flat, marshy landscape. It functions as an educational path with signage detailing the unique hydrographic conditions of the park. The route is circular, starting and ending near the Stare Załucze area. It is a vital site for observing European pond turtles and carnivorous sundew plants in their natural environment. The trail structure requires maintenance due to the high moisture levels of the surrounding terrain.
The observation tower near Lake Moszne offers the best panoramic view of the wetland horizon.
Bring high-quality insect repellent, as the marshy environment is a breeding ground for mosquitoes and horseflies.
Use polarized sunglasses to better see into the dark, tannin-rich waters of the bogs and lakes.
Stay strictly on the wooden boardwalk, as stepping into the surrounding moss can damage fragile ecosystems and pose a personal safety risk.
Do not attempt to traverse the trail after heavy rain, as wooden planks can become extremely slippery and certain sections may flood.
The trail may be closed periodically during spring thaw or heavy flooding; check local park status updates before visiting.
No smoking, no littering, and maintain a quiet volume to increase the chances of observing shy wildlife.
