Before the construction of the entrance road in the late 1930s, the Frey Trail (1.5 miles one way) was the main route to enter and exit Frijoles Canyon. The trail begins at Juniper Campground and makes its way to the edge of the canyon where it switchbacks down to the canyon floor (>550′ elevation change). The trail provides excellent bird’s eye views of Tyuonyi as well as a foot route from the campground to the visitor center. Hiking up is a somewhat strenuous trail at any time, it can be exceedingly hot and difficult in summer as there is little shelter from the sun along the trail. Be sure and always carry plenty of water.

In 2018 the Frey Trail was resurfaced from where it enters Frijoles Canyon, to where it joins the Main Loop Trail. Hiking down is now a wonderful relatively easy walk with amazing views. Just be sure to bring water. Also during summer (mid-May to mid-October) hike down the Frey Trail and take the shuttle bus back up to the trailhead. Shuttle buses stop running at 5 PM daily.

Bandelier National Monument sits at the southern end of the Pajarito (Spanish for little bird) Plateau. The plateau was formed by two eruptions 1.6 and 1.4 million years ago. Home to the Bandelier Wilderness, Bandelier ranges from 5340 ft at the Rio Grande to the south and 10199 ft at the summit of Cerro Grande to the north, almost a mile of elevation change in just under 12 miles. This elevation gradient creates a unique diversity of habitats specific to Northern New Mexico. The diversity of habitats and quick access to water supported a relatively large population of Ancestral Pueblo people. Currently, Piñon-Juniper woodlands dominate in the southern parts of the park transitioning through ponderosa pine savannahs and forests finally reaching mixed conifer forests at the highest elevation. Scattered throughout the park are desert grasslands, montane meadows, and riparian areas in the canyon bottoms. Bandelier is home to a wide variety of wildlife. The backcountry trails at Bandelier climb in and out of deep canyons and cross large flat mesas, showcasing the entire spectrum of volcanic geology.

Bandelier is set within vast amounts of open space. North and west of the park rests the Valles Caldera National Preserve (VCNP), an 89,000-acre nature preserve, which was created by the eruptions that formed the Pajarito Plateau followed by volcanic subsidence. On all sides of the park sits over one million acres of the Santa Fe National Forest, with the Dome Wilderness adjoining the western edge of Bandelier Wilderness. A large portion of the northeastern boundary is shared with Los Alamos National Lab, which covers 26,500 acres of restricted, mostly open space. Bandelier’s direct neighbors make the park’s 34,000 acres feel much larger than it is.

Access to Bandelier National Monument is by a free shuttle bus in the summer months.
