Southwest of Taos and Ranchos de Taos, the Rift Valley Trail is part of the excellent Taos Valley Overlook Trails network spread across rolling riparian terrain above the Rio Grande River. The Rift Valley Trail is an 11 mile mountain bike loop around the outer edge of the trail network. If the loop is too much for your time, there are numerous cutoffs to create smaller loops.
After a long day of Taos mountain biking, try grabbing a long soak in one of the two primitive hot springs along the shores of the Rio Grande River. The Manby Hot Springs are located northwest of Taos and north of the Taos Airport. Also known as the Stagecoach Hot Springs, the trailhead is accessible from Tune Road across from the airport (lat: 36.512144 / long: -105.718169). The Black Rock Hot Springs are located northwest of Taos and west of Arroyo Hondo near the John Dunn Bridge. Also known as the the Hondo Hot Spring, the trailhead is located off CR8007/8005 on the west side of the John Dunn Bridge and then a half mile hike south down the trail (lat: 36.532597 / long: -105.712026).
To reach the Rift Valley Trail mountain biking trailhead from Taos Plaza, head south on Paseo Del Pueblo (SR68) for about 9.8 miles. The signed trailhead parking area is on the northwest side of the road.
