The best time to go to Kolari depends on the activities you're interested in, with distinct advantages for both the winter and summer seasons.For those seeking a classic Lapland experience, the winter months, from approximately November to April, are ideal. This period offers reliable snow cover, making it superb for activities like skiing, snowboarding, and snowshoeing at the nearby Ylläs ski resort. You'll also have the best chance to witness the Northern Lights, especially from late autumn to early spring when the nights are long and dark.If you prefer warmer weather and outdoor exploration without snow, late spring and summer, from May to September, are excellent choices. During this time, the fells are green, and the midnight sun allows for extended daylight hours, superb for hiking, mountain biking, and fishing.
