Echo Canyon Trail, one of Camelback Mountain’s most frequented routes, will remain closed as Phoenix crews tackle lingering safety hazards caused by recent storm-related erosion. City officials say three large, unstable boulders above the trail continue to pose a risk despite weeks of engineering work.
The Phoenix Parks and Recreation Department first shut down the trail in mid-October after signs of potential slope instability appeared. Since then, teams of geotechnical and civil engineers have studied the site and drafted a remediation plan aimed at preventing rockfall. Work began the week of Nov. 24 and is scheduled to continue into the week of Dec. 8.
This next phase involves drilling into each of the compromised boulders and injecting expanding grout—a technique that allows the rock to separate in a controlled, predictable way. Afterward, crews will restore the surrounding terrain to blend naturally with Camelback’s landscape. Engineers have reported progress, but say the boulders remain hazardous until the process is complete.
“We’re taking a careful, methodical approach to restore Echo Canyon, and we appreciate the community’s patience while we ensure the trail is safe again,” Parks and Recreation Director Cynthia Aguilar said.
While the popular route is closed, the city is also using the downtime to renovate restrooms, refresh the parking lot, and complete other trailhead upgrades—steps officials say will prevent future closures once Echo Canyon reopens.
Hikers looking for alternatives are encouraged to explore nearby options, including Cholla Trail, Piestewa Peak, North Mountain, Dreamy Draw, Lookout Mountain, and South Mountain Park. More information on trail choices can be found through the City of Phoenix’s trail directory.
