Alta-Bajada Loop

The Alta-Bajada Loop is best enjoyed during the cooler months, typically from late fall through early spring. Summer temperatures in Phoenix can be extreme, making this strenuous trail unsafe for jogging during those months.

The terrain is primarily dirt, with sections that can be rocky and even require some scrambling. The Alta Trail portion involves a relatively quick and steep climb, while the Bajada Trail section is generally flatter and runs roughly parallel to the road.

Specific parking information for the Alta-Bajada Loop trailhead within South Mountain Park can vary. It's recommended to check the official South Mountain Park and Preserve website or local trail maps for the most current parking areas and access points. Arriving early, especially on weekends, is often advisable to secure a spot.

The Alta-Bajada Loop is generally considered a difficult trail, suitable for experienced joggers or trail runners. Its significant elevation changes, rocky terrain, and steep climbs, particularly on the Alta Trail, make it a challenging workout. Beginners might find it too strenuous.

Given the trail's difficulty and desert environment, it's crucial to bring plenty of water, especially during warmer periods. Sun protection (hat, sunscreen), appropriate trail running shoes, and a map or GPS device are also highly recommended. Consider bringing snacks for energy and a first-aid kit.

The primary challenge is the significant elevation gain, especially the steep ascent on the Alta Trail. An insider tip is that the Bajada-National sections offer a more remote experience with fewer crowds compared to other popular areas of South Mountain. Starting early in the morning, especially outside of peak winter season, can help avoid the hottest part of the day and secure better parking.
