Mack Ridge/Kokopelli Trails provides outstanding single-track mountain biking opportunities. Trails range in difficulty and skill level. Rustler's Loop, for example, is designed as a practice loop where riders can hone their skills - educational signs give tips and advice for those new to the sport of mountain biking. The area provides excellent views and scenery of the Colorado River and beyond. It is close to the City of Fruita.
From Hwy 70, take the Loma Exit (15) and travel south. Follow the signs to the trailhead.
