Winter months provide a number of activities to keep even the most adventurous family happy.
Start at the North end of Flathead Valley for some world-class skiing at the Whitefish Mountain Resort (Big Mountain). Tour the backcountry on snowshoes or cross-country skis or stick to the miles and miles of groomers on your snowboard, alpine or telemark skis. When you tire of the great outdoors, lounge in the village or bum the shops in town.
Whitefish Golf Course turns into the Glacier Nordic Center in the winter, with 9 miles of touring trails good for cross country or skate skiing.
Blacktail Mountain Ski Area is on the South end of the Flathead Valley and covered with snow. Runs are a bit shorter, but so are the lines. There are also dog sled rides and over 200 miles of groomed alpine trails for snowmobiling.
