A broad desert trail beneath summer clouds at Usery Mountain Regional Park near Mesa

Mesa, AZ

Merkle Trail

A 0.9-mile barrier-free loop at Usery Mountain Regional Park, with gentle grades and an accessible desert-trail option for varied-ability groups.

Why it belongs in the guide

Merkle Trail is the clearest low-barrier introduction to Usery Mountain Regional Park. Maricopa County lists the loop at 0.9 mile with 68 feet of elevation change and classifies it as barrier-free with the easiest rating. The park also describes it as suitable for strollers and wheelchairs, making it a useful option when a group wants desert scenery without a steep climb.

Barrier-free is the park's trail classification, not a promise that every mobility device will handle every day's surface conditions. Restrooms are near the trailhead, but a 2026 county program notice says there is no water at the trailhead. Bring water even for this short loop and check current alerts before traveling. General county rules allow leashed pets on designated trails, although a particular ranger program may set stricter rules.

Confirm current hours, fees, alerts, and trail conditions on the official Usery Mountain trail page. Accessibility context is also available in the park's official itinerary. Usery Mountain Regional Park photo: Z Glyph/Wikimedia Commons, licensed under CC BY 3.0.
