That depends entirely on what your clients want to see and do while they are here. Summer, from early June to mid-August, is perfect for roadtrips, sightseeing, wildlife viewing and outdoor adventures. Late August and September brings autumn weather and colours, as well as the beginning of northern lights viewing. Winter, from November to April, is the time to see northern lights and enjoy winter activities like dog sledding, snowmobiling or ice fishing. Spring, from late April to late May, is a period of melting and thawing, while animals come out of hibernation after the long winter.
