Take your dog to Marcus Landslide Trail to enjoy sweeping views of the Sonoran Valley on an easy hike. This is the second largest landslide in Arizona and as a result, there are incredible rock formations, many of which are marked by educational signs explaining their geological significance. The trail is just under four miles long, including an optional .7 mile loop, with only a 300 foot elevation gain. Come in spring to see the wildflowers bloom. Make sure to bring plenty of water for both yourself and for Fido, as there is no shade and no water at the trailhead. Dogs must be leashed at all times.
