Join Ranger Eric and park host Terry Zaugg for a guided hike on the Preserve's trails to learn about the riparian and upland Sonoran Desert plants growing here, and their ecological and cultural importance. Trail difficulty is low to moderate, with one steeper stretch on the way up to Lyke's Lookout, which offers a scenic vantage point of the river and surrounding desert. Registration is required and space is limited. To register, please call the Visitor Center at 928-684-2772.
