The Knife Edge is a narrow ridge of rock separating two branches of the Ancho Canyon drainage. The ridge narrows to become only a few yards wide, offering nice views in both directions. The trip is an easy walk on an old dirt road through piñon and juniper woodlands, and in spring you can find some early wildflowers growing along the way. It is a nice outing for families and a great early-season trip for anyone.

Map of Deer Trap Mesa Trail.

One of the finger mesas extending east from the Pajarito Plateau, Deer Trap Mesa offers the most consistently scenic hikes on the plateau. In addition, the terrain is rather flat, with a couple of exceptions. The main trail passes by the game pit for which the mesa was named, then follows a well-worn path across a narrow section of mesa with views on both sides. A loop trail, located on Los Alamos County Open Space, leads to several overlooks of the Pajarito Plateau and Sangre de Cristo Mountains to the east. The view is constantly changing, and immensely enthralling. The most challenging section of trail is in the first 100 yards, a short, narrow, steep descent on an Ancestral Pueblo stairway that seems tricky but is rather easy and not dangerous if carefully navigated. Almost the entire canyon edge trek follows segments of three-finger mesas and is just over 3 miles long. Some sections are muddy after rains, but because of a general lack of shade, the trail dries out quickly. This is an ideal spring, fall, or winter hike, but it does get quite warm at mid-day in summer.

Trail Name: Neblina’s Trail

Map of Neblina’s Trail.

A short, shady trip up the Neblina’s Trail offers a quiet getaway close to town. The trail traverses under tall pines and is a cool trip even on a summer afternoon. The area was relatively untouched by the Cerro Grande fire, although the stream channel is choked with debris from floods following that fire and the Las Conchas fire. Tall, orange cliffs flank the canyon, and the trip ends in a narrows where cliffbush thrives in a thick stand.
