Downhill both ways (ha) through Pinon and Cedar forest at the foothills of the Sangre de Cristos. Ripping fast with some tech thrown in. Early season favorite amongst locals and a great quick ride through most of the year.
From Taos head east on Canon Bypass (go left at Chevron and Visitors Center) head up hill past Taos Youth and Family Center and the Charter School. Just past the school you will see a blue water tower on top of a hill, park under this tower. Climb up hill towards tower, go left through gate. At this point you are on Ojitos Trail an option for coming down off of South Boundary. Climb this old jeep rd over multiple whoops. After approx. 10 whoop look to your right and you will see singletrack descending an arroyo. Take this trail.
