Geronimo Trail

The Geronimo Trail is an adventurous hike in Phoenix’s South Mountain Preserve. This route is 4.8mi of varied terrain, with some sections crossing over big boulders, some rocky footing, sandy parts, and a bit of everything in between. It’s a fun way to take on lightly technical terrain in a low-consequence way. At the end of the hike, there’s a bench from where you can admire the city sprawling below you. Watch for mountain bikers in the middle third of the hike. This route might be a bit too tough for small kids.

Note that there isn’t parking available right at the trailhead. You can park at the eastern end of E Dobbins or find a space along S 20th Street, but make sure you’re not in a tow-away zone.

This trail has 3 distinct sections. From the trailhead heading uphill, the first climb is very rocky. You’ll ascend through switchbacks before the route levels out with a bit of undulation. The final stretch of the route to the end is where you’re most likely to encounter mountain bikers, so stay aware of your surroundings. This final section is less rocky but much sandier so be sure of your footing.
From the top, take in the view before retracing your steps to the starting point.
