This study investigates the impacts of tourism on vegetation and soil on campsites in Pallas-Yllastunturi National Park, Northern Finland. Altogether, 19 campsites were surveyed to estimate the current condition of campsites and to specify factors affecting the amount of disturbance. Our results indicate that the location of campsite structures is the most important factor determining the size of disturbed area on campsites. Distance between wilderness huts and campfire sites explained the size of disturbed area, whereas the age of the campsite and number of visitors had no impact. The total disturbed area on campsites varied between different vegetation types, mountain biotopes being the most sensitive. Our results suggest that the disturbed area can be minimized by locating campsites in trampling tolerant environments and by building the structures compactly within each campsite.
