Norway has 43 national parks, of which 36 are on the mainland and 7 on Svalbard. National park regulations in Norway are stricter than many other countries, and nearly all motorised vehicles are prohibited. The freedom to roam applies, thus hiking, skiing and camping throughout the park are permitted, provided that consideration to nature is taken. Roads, accommodation and national park centres are located outside the national parks. Ytre Hvaler is a marine park and all parks in Svalbard also contain marine areas. Sør-Spitsbergen is the largest park, covering an area of 13,286 km2, although only 5,141 km2 is land. The largest park on the mainland is Hardangervidda, which covers an area of 3,422 km2. Gutulia is the smallest, covering 23 km2.
