I've never been a skier, but hubby and I are dedicated snowshoeing fans. Does that count? While it's unlikely we'll die out there after hitting a tree, snowshoeing is tremendous exercise: giving one the benefits of a 10 mile hike for 5 miles.
We typically go for a 4-6 mile snowshoe outing at elevations of 8,000 -11,000 feet.

PS: See that white line in the background? That's the closed-in-winter road we trekked up, breaking trail the entire way. Great, great workout.
