This is the epic trail that experienced riders do not want to miss. The trail begins in Angel Fire with 22-24 mile singletrack ride, (depending upon where you start), back to a finish, (at the El Nogal picnic area), three miles from the center of Taos.
There are also several other access points to the South Boundary trail. If you can only do a portion of the SBT ride the Heaven on Earth trail section as an out-an-back. Or ride the 40-mile-ish SBT BigRide Course as a shuttle.
We always recommend a paper map if you’re riding the backcountry in Taos, in addition to using a map app on your smartphone.
