East of Alpine in the Apache-Sitgreaves National Forest, the Williams Valley Loop uses established cross-country ski trails. This non-motorized area is prime for exploring large meadows and some of the finest aspen forests in the state. Most of the trails are smooth and rolling, but there are two hills which will make you grunt on the way up, and scream all the way doooooooooown!
To reach the mountain biking trailhead from Alpine, head north on US191 for 1.5 miles. Turn left heading west on FS249 for 4 miles to trailhead parking area.
Overall, Williams Valley Loop is the 76th most popular mountain bike trail of all 103 mountain biking rides in Arizona.
