Kampinos Dunes and Swamps Trail (Granica to Dąbrowa Leśna)

The Kampinos Dunes and Swamps Trail crosses the heart of Kampinos National Park in Masovian Voivodeship, Poland, starting in the Granica area of Izabelin municipality and heading toward Dąbrowa Leśna. The park protects a landscape unusual for Central Europe: parallel inland dune ridges, formed after the last ice age, separated by peaty swales and alder swamp. Access from Warsaw is by bus 708 or 719 from Metro Młociny to the Izabelin and Granica area, on a ZTM ticket costing 4.40 PLN (about $1.20). Drivers can leave cars at designated spots near Granica. Most trails in the park are free to enter, and no permit is needed for walking on marked paths. The route covers 15 to 20 km and takes four to six hours. Elevation changes are modest, around 20 to 40 m between dune crests and wet swales, but the soft sand makes progress slower than the distance suggests, which justifies a moderate rating. Surfaces vary between loose dune sand, firm forest tracks and wooden boardwalk sections across wetter ground. Dune crests are open and exposed to sun and wind, whereas the pine and mixed forest between ridges is shaded. Key landmarks include the dune ridges themselves, the old pine forest and the swamp boardwalks, where birdlife and occasional elk or deer sign can be seen. Because waymarked trails cross and intersect frequently, hikers can pick a turn-around point at nearly any junction and return along a parallel path. There are no refuge huts on the route and no reliable drinking water, so at least 1.5 litres per person should be carried. Mobile signal is patchy, and an offline map is strongly advised. After rain, swales can hold standing water and boots that tolerate wet sand are useful. The wetter areas support many mosquitoes in midsummer, and ticks are present from spring through autumn.
