). Sulitjelma, located 44 km by road east of Fauske, is a good starting point for hiking in the mountains and hikes to the glaciers. There are several DNT lodges in this area.

).Climate Fauske is located inside the Arctic circle and has 24-hr of daylight from early May to the beginning of August, with midnight sun from the beginning of June to the second week of July. Average 24-hr temperatures in Fauske is below freezing from mid-November to the last part of March, but the ice free fjord moderates winter temperatures. Summer starts in June with summer temperatures lasting until early September. Precipitation is heaviest from September to December (usually as snow in December); average annual precipitation is 1040 mm. Daytime temperatures are usually significantly warmer than the 24-hr average from March to September, while there is very little diurnal temperature variation from November to early February as the sun is very low or below the horizon all day. However, temperatures varies considerably with the weather; there might be cool westerlies with 10°C and rain both night and day in July, and the next day might be sunny with daytime temperature reaching 25°C. Southwesterlies can bring thaws anytime in winter, but not in the mountains, which usually get large amounts of snow in winter - the main reason for the large glaciers and the hydropower in the area.
