The Atalaya Mountain trailhead () is at St. John's College, where there is parking. St. John's Trail (TR 174) follows along the Arroyo de los Chamisos, enters and exits the arroyo to the left and crosses Wilderness Gate Rd., turning into the Atalaya Trail (TR 170). It is also possible to enter the Atalaya Trail from the Dale Ball Trails via two access trails. One from the direction of Picacho Peak directly to the summit of Atalaya Mountain, and another near the Wilderness Gate residential area, west of Wilderness Gate road. The Atalaya Trail branches into Hard Atalaya (TR 172), where a signpost directs hikers straight for "Steeper Route" or right for "Easier Route". Both routes connect higher up the main trail (TR 170). Older trail maps might label the "Easier Route" the "newer bypass", and the "Steeper Route" the "original route, TR 170". Coming back from the summit, one should be careful not to follow a route into the Santa Fe Watershed, a protected area that is off limits to the public. Two trailheads located on Camino de Cruz Blanca allows one to skip hiking most of the Saint Johns trail to access Atalaya Trail, but provide only minimal parking.
