Submerged Forest at Łącka Dune

Highlight • Natural Monument

The Lontzkedüne (Polish: Wydma Łącka) is the largest shifting dune on the Pomeranian Baltic coast. It has the shape of a sickle or a crescent moon and is part of the dune area, which covers an area of approximately 500 hectares. The natural dune lies on the 17 km long spit between the Lebasee and the Baltic Sea. It is between 30 and 42 meters high, about 1300 meters long and 500 meters wide and moves about 12 meters a year to the east due to the prevailing westerly winds. It buries the original landscape, forest and moor under itself. Łączka was buried by the dune in the past. On the west side leaning towards the wind, the dune has a slight slope, while on the side leaning towards the wind, the slope is very steep. From a wind speed of 18 km / h, the grains of sand begin to roll up the flat side until they fall down on the upper edge on the sheltered side. While the dune grows in height in spring and summer with rather weak winds, it flattens out in stronger winds in autumn and winter and then reaches a higher migration speed. On the back of the shifting dune, stump fields of former forests come to light.

We were in Leba in January and experienced the power of the wind and certainly experienced the hiking of the dune more intensely than it can be experienced in summer.

Łącka Dune

Highlight • Natural Monument

The Lontzkedüne (Polish Wydma Łącka) is the largest shifting dune on the Pomeranian Baltic Sea coast. Shaped like a crescent or crescent, it is part of the dune area, which covers an area of approximately 500 hectares. The natural dune is located on the 17 km long spit between Lake Leba and the Baltic Sea. It is between 30 and 42 meters high, about 1300 meters long and 500 meters wide and moves eastwards about 12 meters a year due to the prevailing westerly winds. She buries the original landscape, forest and moor under her. In the past, Łączka was also buried by the dune. On the west side, facing the wind, the dune has a gentle slope, while on the leeward side, the slope is very steep. From a wind speed of 18 km/h, the grains of sand begin to roll up the flat side until they fall down the upper edge on the wind-protected side. While the dune grows higher in spring and summer when the winds are rather weak, it flattens out in stronger winds in autumn and winter and then achieves a higher migration speed. On the back of the shifting dune, stub fields of former forests come to light (Wikipedia).

Lackawanna Dune

Highlight • Natural Monument

A beautiful and well-known dune and elevation of variable height (it's a dune, so it's mobile!), approximately 30 meters above sea level, on the Łeba Spit. Beautiful, fantastic views – a truly unique natural wonder.

Łącka Dune

Highlight • Natural Monument

Passage is zero here because the highest points of the large shifting dune reach a good 50 meters. All of this a fine sandy subsoil where hiking also causes a little difficulty. So pushing and carrying is the order of the day.

Trail to Łącka Dune

Highlight • Trail

The expanses and the mountains of sand are gigantic. The wind on the beach is strong. The route is easily accessible on foot. Allow 4 hours to enjoy the tour.
