Łeba is a small fishing port and beach resort on Poland's Baltic coast, best known for the Słowiński National Park that brackets it on both sides. The park's crowning feature is the Łącka Dune, one of Europe's largest moving sand dunes — a wall of white sand that creeps steadily inland, slowly swallowing the forest behind it. The sight of pine trees half-buried in sand is genuinely strange and memorable. Lake Łebsko, a vast coastal lagoon within the park, stretches south of the dune trail and is an important wildlife habitat.
In summer, the town fills with Polish holidaymakers who come for the broad, clean beaches and the sea air. Outside peak season it's quiet and a little melancholy, which suits it well. The harbour where fishing boats come in has the best seafood in town, and north along the beach a curious WWII relic awaits: a German rocket testing range used in the 1940s, now an open-air museum whose concrete bunkers still stand in the dunes.
