The Itinerary: What to Expect on This Guided Hike

The adventure begins at the Mormon Trailhead in South Mountain Park, where your guide will meet you ready to introduce you to the landscape. From there, the focus is on exploring the Hidden Valley, a natural bowl surrounded by massive rock formations that seem almost sculpted by the gods. The trail is about four miles roundtrip with an elevation gain of roughly 1,117 feet, so be prepared for some ups and downs.

Exploring the Landmarks: Fat Man’s Pass and Natural Cave

One of the most memorable parts of the hike is navigating Fat Man’s Pass, a narrow, low corridor between two boulders that requires a bit of scrambling. It’s a fun challenge, especially if you enjoy scaling rocks and squeezing through tight spaces. Adjacent to it, you’ll find the Natural Cave, a sheltered spot carved into the rocks—perfect for a quick break and some photos.

Rock Formations and Tunnels

The terrain is studded with giant boulders, rock tunnels, and dry waterfalls that you’ll hop over and slide down. These features not only create excellent photo opportunities but also give you a real sense of the desert’s geological history. The guides often share insights into how these formations came to be, making each stop educational as well as visually fascinating.

Ancient Petroglyphs and Abandoned Mine

A highlight for many is discovering petroglyph sites, where ancient rock art tells stories from thousands of years ago. These carvings are accessible, but you might need a keen eye to spot them among the rocks. The guides take care to point out these details and explain their significance. Plus, the tour includes a visit to an abandoned mine, adding a touch of Arizona’s mining past to your desert adventure.
