The Traena Music Festival is held annually in the municipality of Træna in Nordland county, Norway. The festival is held on the islands of Husøya and Sanna. The islands are only accessible by ferry boat from the mainland in Lurøy.
Venues have included an ancient cave, a church with blacked-out windows (to block out the Midnight sun which shines for 23 hours a day), and tents. The festival attracts many people from neighbouring communities who visit the camp to enjoy the music and unique nature of the festival.
