More than 300 miles of groomed trails set a course for snowmobilers of all abilities to tour spectacular mountain terrain. Warming huts provide winter enthusiasts with a cozy place to rest and plenty of parking is available for all to enjoy this scenic area.

It's a river's birthplace. One hundred and twenty million gallons of pure water a day -- enough to meet the water needs of a million people -- surge out of the ground here. A short distance from the glassy pool is a bridge. Toss bread crumbs into the water from it, and you'll see that constant flow (at a year-round temperature of 52 degrees) and the clean gravel bottom make for perfect trout habitat. Big Springs' trout get BIG. Leave your fishing pole in the car, though: No fishing is allowed until below the outlet to Henry's Lake, several miles away.

Take the short walking trail around the pond to reach Johnny Sack's cabin. Johnny was a German immigrant who built his cozy cabin and its furnishings by hand out of local trees. He also built a water wheel turned by spring water tumbling out of the hillside. The wheel provided electricity and brought water uphill to the cabin. Johnny's old place is now a visitor center and an attraction in its own right.
