JUNE – AUGUST. Jukkasjärvi in summer is a paradise to nature lovers and active holiday enthusiasts; mild temperatures makes it ideal for hiking, cycling, wild life watching and running. Though now in its fluid form, we are just as passionate about water experiences and the Torne River, which is really our specialty. River rafting, stand up paddle surfing, fishing, canoeing and sauna are some of the favorites. You can also rent your own equipment at Icehotel.
