The Baltic Coastal Hiking Route starts in Nida’s centre next to the port.

Nida’s architecture is full of authenticity, with its historical single storey homesteads, thatched roofs and white and blue wooden shutters. From Nida to the Horn of Bulvikis, the route passes an abandoned airport runway and dives into the fragrant pine forest and occasional sandy meadows that feature very specific Curonian flora. There are several picnic areas and bird watching stations on the way.

After Pervalka, the route moves over to the western side and reaches the Baltic sea. The next 13 km follow a picturesque sandy beach that leans onto a steep, high beach dune. It is manmade in an effort to protect the peninsula from the relentless travelling sand. Before reaching Juodkrantė, the route crosses the pine forest, through a fragment of the Hill of Witches and onto the wide lagoon promenade of Juodkrantė’s shore and towards the port.

The route reaches the ferry crossing where the splendid city centre of Klaipėda awaits.
