Join Ranger Eric for a guided hike on the Preserve's trails to learn about the riparian and upland Sonoran Desert plants growing here, and their importance to the local ecosystem. 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 during normal business hours (Wednesday-Sunday, 8:00am-5:00pm). Admission to the Preserve is $5/adult (age 13 and up). Maricopa County Parks annual passes are honored here.
