Flottkalaset
Flottkalaset (Raft Festival) is an annual music festival and cultural event held in Tjautjas in the Gällivare Municipality region in northern Sweden. The event was envisioned and organized by Riksspelman Daniel Wikslund, a noted Swedish folk musician. The two-day festival takes place in August on an island in the middle of a mountain lake, accessible via rafts or by walking across a raft bridge.
