The shifting dunes move at an average rate of 3 to 10 meters per year, depending on wind intensity.
The park contains 'skeletal' forests, which are areas where sand dunes have buried trees and subsequently uncovered their bleached, dead trunks.
Lake Łebsko is the third largest lake in Poland and is separated from the Baltic Sea by a narrow sandbar.
The dunes are part of the Pomeranian landscape and were shaped primarily by the Baltic Sea's post-glacial activity.
The park was designated a RAMSAR site in 1995 to protect its significant wetland habitats.
It is a popular location for studying aeolian processes, which involve the wind's ability to shape, transport, and deposit sand.
Archaeological finds in the region suggest human settlement dating back several thousand years, often buried by the encroaching sands.
Słowiński National Park is a UNESCO World Biosphere Reserve on the Baltic coast, defined by its massive, shifting sand dunes. The park preserves a unique ecosystem of coastal lakes, marshes, peat bogs, and coniferous forests. The Łącka Dune is the most prominent feature, reaching up to 30 meters in height and migrating eastward due to wind patterns. The park encompasses two major lakes, Łebsko and Gardno, which are remnants of ancient sea bays. It is a vital migration stopover for waterfowl, with over 250 bird species recorded in the area. The landscape is characterized by its dynamic geology, where advancing sands have historically buried forests, leaving behind fossilized 'ghost' tree stumps. The park administration is based in Smołdzino, which serves as the primary gateway for research and visitor information. It is one of two national parks in Poland located on the Baltic Sea coast.
The summit of Łącka Góra, offering panoramic views of the sand landscape against the sea.
Bring polarized sunglasses to reduce the intense glare reflecting off the white quartz sand.
Wear sturdy footwear suitable for walking on loose, deep sand as trails are not paved.
Carry sufficient water, as there are no natural sources of fresh water once you enter the dune field.
Protect camera equipment from fine, wind-blown sand that can damage sensitive mechanisms.
Attempting to climb non-designated dune faces which causes rapid erosion; arriving without adequate wind protection on breezy days.
The park is open year-round, though access to certain restricted nature trails may be temporarily limited during bird nesting seasons.
Stay strictly on marked paths to prevent erosion of the fragile dune vegetation; swimming is prohibited in the lakes.
