The Upper Rio en Medio Trail is a popular, challenging 1.9-mile trail located near Santa Fe, New Mexico. It features a mix of steep grades, tight switchbacks, rock gardens, creek crossings, and scenic waterfalls, making it ideal for experienced mountain bikers seeking a backcountry adventure. This downhill-only trail begins near the Santa Fe Ski Area, following the river with a tough initial section before transitioning into smoother, faster segments. As you draw closer to Aspen Ranch, there are several alternative paths you can take if you want to change things up. At Aspen Ranch you have a few options: you can continue down the Lower Rio en Medio trail for a truly epic backcountry experience that takes you all the way down to the base of the mountains (shuttling cars is a must, unless you want an even more epic day), or, if you haven't shuttled a car to Aspen Ranch), you can turn back uphill to Ski Santa Fe on the Aspen Ranch Road (Forest Road 412), which you can connect to Pacheco Canyon (Forest Road 102) and either back up to the paved road or to the Winsor Trail. Although riding on trails is usually preferable, the Winsor Trail is usually ridden as a downhill trail and is very popular with hikers, making it for a sometimes trying uphill experience. Regardless of what you do at the end of the Upper Rio en Medio Trail, it's a truly fabulous section of backcountry downhill riding in the mountains above Santa Fe.
