Devil's Jaw (likely referring to Djevelens tanngard), situated near Finnsnes on the stunning island of Senja, offers an extremely challenging but incredibly rewarding hiking experience to a series of jagged peaks known for their breathtaking panoramic views. This demanding trek, best suited for experienced hikers with excellent physical fitness and no fear of heights, typically requires 6-10 hours to complete. While adventurous solo hikers can attempt it, a local guide is highly recommended for safety due to the steep, exposed, and often scrambling terrain. Accessibility primarily involves reaching Senja, often by car, to access trailheads such as those near Mefjordbotn. The optimal time to visit is during the summer months (June-August) when trails are clear of snow and ice; winter conditions render it dangerous and often inaccessible. There are no entry fees, but costs will include transport to and around Senja, accommodation, and essential hiking gear. Always bring ample water, food, navigation tools, and layered clothing as mountain weather can change rapidly.
