Atascosa #100 the Forest Service's write-up

This trail appears on most maps as an insignificant, isolated squiggle leading 2.5 miles to the site of where an old fire lookout was prior to its burning down in the Murphey Complex Fire of 2011. As far as trails are concerned, it may be one of the best kept secrets in southeastern Arizona. Some who have come here describe the views from this soaring desert butte as enchanting. Others have said that Atascosa Peak rises high enough above the surrounding landscape to provide a panorama, but not so high that the landmarks making up that view fade into insignificance. That may be the secret of this spectacular little stroll into the sky above the buttes, bluffs, and canyons that lie just north of Arizona's border with Mexico. The trail itself climbs steadily, even steeply in places, but neither so long nor so relentlessly that it is exhausting. The view expands steadily as the trail switchbacks higher, first parading past nearby buttes and cliffs that thrust above grassy foothills, then providing magnificent panoramas that stretch to distant horizons. Trailside vegetation is stunted by the desert conditions and puts little between you and the sublime views. Castle Rock, Montana Peak, the spires and cliffs of Sycamore Canyon, the corduroy cañoncitos around Nogales catch your eye to the south. To the west, there is Baboquivari Peak, sacred to the Tohono O'Odham, and the white buildings of famous Kitt Peak Observatory. The Santa Ritas and Huachucas are just a few of the landmarks visible to the east. On a clear day, you can see the Piñacates of Mexico and, some say, even the glint of the Sea of Cortez. A final flurry of switchbacks takes you to the peak's summit. Take lunch and stay awhile.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
