Sweden's water experiences are shaped by 3,218 kilometres of coastline and an archipelago of 267,570 islands. Stockholm Archipelago sailing tours — navigating between the forested granite islands of the outer archipelago under sail, anchoring at fishing village jetties and swimming from the bow at deserted rocky islets — are the most specifically Swedish leisure water experience. Göta Canal narrowboat holidays between Stockholm and Gothenburg, crossing the interior lake system through 58 locks over five days in a journey that was described by Hans Christian Andersen as 'the most beautiful in the world,' and Arctic Sweden icebreaker tours from Luleå in February add range. Icefjord glacier kayaking in the Sarek wilderness, Midnight Sun Lapland river rafting from Arjeplog, and the Kosterfjord sea kayaking route through Sweden's first marine national park complete an exceptional water geography.
