Mormon Trail and Hidden Valley Loop

The most common access point is the Mormon Trailhead in South Mountain Park and Preserve. There is parking available there, but it can get busy, especially on weekends. Arriving early is recommended to secure a spot.

While the overall route is rated as difficult for jogging, the initial mile of the Mormon Trail is particularly challenging due to its steep, rocky, and consistent uphill climb. This section might be better suited for power hiking. The Hidden Valley portion has flatter or gradually descending sections that are more conducive to sustained running. Good trail running shoes are highly recommended due to the varied and often rocky terrain.

The terrain is quite varied. You'll encounter rocky, uphill sections with switchbacks, especially on the initial Mormon Trail ascent. Footing can be challenging due to large boulders. Within Hidden Valley, you'll find a mix of sandy paths, rock formations, and sections requiring boulder scrambling. The trail is largely exposed to the sun, with minimal shade except for the natural tunnel.

This route offers several distinct features. You'll get panoramic views of the Phoenix area, including downtown, Camelback Mountain, and Piestewa Peak, especially from the View of Phoenix from Mormon Lookout. The Hidden Valley portion features impressive rock formations, a natural tunnel, and the famous Fat Man's Pass, a narrow squeeze between boulders (with bypasses available). You might also spot faint petroglyphs and a natural rock slide.
