People Walk on Frozen Baltic Sea - Police Warn - Rügen's Baltic Sea freezes into a stunning but deadly winter wonderland

The Baltic Sea around Rügen has transformed into a striking icy landscape this winter. Thick ice formations now stretch far beyond the shoreline, drawing crowds eager to explore the frozen scenery. However, authorities have issued urgent warnings about the dangers of venturing onto the unstable surface.

In January and early February 2026, ice thickness in protected areas like the Greifswalder Bodden and the strait to Hiddensee has reached 15–20 cm. This marks the first significant freeze in five years, though historical records show far harsher winters, with ice up to 65 cm thick across the Baltic. Shallow, freshwater-rich zones such as the Haff and Bodden typically freeze first.

The frozen seascape has captivated visitors, particularly around the eastern breakwater and the lighthouse near Sassnitz. Striking ice formations have formed, and even the oil tanker Eventin, anchored offshore, is now surrounded by ice. Yet the beauty hides serious risks.

Water police have repeatedly warned against walking on the ice, especially in Sassnitz harbour and along shipping lanes. The Prorer Wiek bay is covered far out to sea, but the ice remains treacherous. Uneven and unstable, it can collapse without warning, even in areas that appear solid.

Despite the alerts, large groups have ignored the dangers. In Sellin, people walked far from the beach onto the frozen surface, while the local pier became completely encased in ice. Authorities stress that the ice lacks the strength to support weight, even outside harbours.

The water police continue to urge caution, highlighting that no part of the Baltic ice is safe for walking. While the frozen scenery has drawn attention, the risks of sudden collapse remain high. Visitors are advised to admire the ice only from solid ground.
