St. Olavsleden is the northernmost pilgrim trail in the world. The trail is approximately 580 kilometers long and extends from the Baltic sea in the East to the Atlantic Ocean in the West, from Selånger in Sweden to Trondheim in Norway. The trail goes through large forests, over mountains, along lakes and past communities and historic sites. The roadbed varies from gravel road, asphalt and trails.
St. Olavsleden is the Scandinavian equivalent to the El Camino de Santiago de Compostela, the famous pilgrim route to Spain.
