The San Dimas Canyon Nature Center was the first nature center in the Los Angeles County Park system opened in the 1950s. For decades, nature enthusiasts have come to discover the center’s unique artifacts, fun facts about the native animals, and learn exciting information about the area and its rich history. Visit for free Tuesdays through Sundays, 9 am to 4:30 pm. Every Saturday from 1 to 2 pm you can hear the staff and Junior Naturalists tell you about some of the animals, reptiles, and other interesting creatures resident at the Nature Center. You'll get to see them up close and personal! Call (909) 599-7512 for more information.
