Another area newly opened for docent-led outings, features vibrant tree and plant communities that make the canyon ideal for large populations of animals, especially birds. A family-friendly 3.6-mile roundtrip hike offers pleasant views of the canyon and its habitats. In nearby Agua Chinon, a fairly strenuous five-mile roundtrip hike takes participants to “the Sinks,” a beautiful formation in Limestone Canyon. Reservations are needed for outings.
