Northside is a self-guided fee-based mountain biking area on 1,200 acres of private alpine wilderness. As a mapped and signed trail system designed especially for mountain biking, Northside is a looped trail network with spectacular overlooks, single and double track routes through pines, aspen, and meadows. The terrain is best suited for the intermediate and higher level rider. For the more adventurous, one can pedal to the top of two mountains. Bull Of The Woods Mountain is approximately 11,640 ft. and the highest is Frazer Mountain at 12,163 ft. and is above tree line. With elevation changes that make your heart pump for joy, the rewards of the effort are heart stopping views and sick downhills. Northside offers the only XC riding in Taos Ski Valley. Northside is open dawn to dusk from mid to late June through October, weather permitting. Access permits are for sale at many locations in Taos Ski Valley or at the trailhead kiosk. Permits are also sold in Taos at Taos Cyclery and Gearing Up Bicycle Shop. Visit our website for more info and photos.
