The central Norwegian area of Trondelag has its ideological capital in Trondheim, founded by Viking king Olaf Tryggvason in the 10th century and the seat of Norway's power until the 13th. Today, it's still the country's third-largest city, a university town with a rich culture. Trondelag's western offshore islands of Hitra and Froya are popular for outdoor adventures like camping, hiking, biking, snorkeling and scuba diving. They are also one of the world's best spots for deep sea fishing.
