January 10, 2024, Mitchell Trail

The Mitchell Trail is a very steep, switchbacking trail thats open to hikers and bikers. Although you can ride up it, it is so gravely, steep, and twisty that most use it as a downhill trail. This trail is very popular with hikers headed to the Los Alamos Arch (which you should check out too!) so be aware as you ride down.

January 10, 2024, Quemazon Trail

The Quemazon Trail is an excellent mountain biking and hiking trail on the westside of Los Alamos. It is typically ridden as a downhill trail accessed from either the Knapp/Los Alamos Canyon Trail or Pipeline Road, but it can be ridden uphill. The Quemazon Trail is a technical trail with stretches of flowy singletrack intermixed with rocks, ledges, and small drops to keep things interesting.

January 9, 2024, Guaje Ridge Trail

The Guaje Ridge Trail is a long, open trail that traverses the amazing ridges of several mountain tops (most unnamed) north of Los Alamos. This section of trail stretches from the intersection with the Mitchell Trail and the Upper Guaje Ridge Trail. Although you're only a few miles from town (as the crow flies), this is an incredibly remote feeling trail.

January 9, 2024, Bayo Canyon Trail

The Bayo Canyon Trail runs from the rotary next to Loma Linda Park to the bottom of Bayo Canyon. The trail starts out on fast, flowy singletrack, but gets steadily more technical as you get close to the bottom of the canyon with steep drops and large rocks. At the bottom of the canyon the trail levels out again before turning into a dirt road that eventually leads out to the highway.
