Willow Fork is an awesome, simple Wasatch backcountry tour. It's full of great low angle terrain, perfect for days with questionable avalanche danger or for beginner backcountry skiers.
Willow Fork is just across the mountain from Solitude Ski Resort in Big Cottonwood Canyon. You can access Willow Fork from a few different trailheads; either from the Willow Heights Trailhead or across the street from both the lower and upper Solitude parking lots.
The Willow Heights Trailhead will take you up to the Beaver Pond Basin where you can either keep left and tour up through West Willows, or your can keep right and ascend Will's Hill to Peak 10,009. The trailheads across from Solitude will take you up to the East Willow Ridgeline and up to the Main Willow face. Both routes offer awesome low angle skiing with some great trees.
Total elevation gain is about 1,700 ft with a max elevation of around 10,000 ft depending on the route you take.
Make sure to check to avalanche forecast for the day before you ever travel in the backcountry. Know before you go!
