Irvine Ranch Natural Landmarks

Enjoy the relaxation of riding in the wilderness on empty trails. Join us on this docent-led mountain bike ride through Weir Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space. We will ride a figure eight route, primarily on ranch roads, but also will ride two non-technical singletrack trails. The route is approximately 10 miles long with 1800 feet of climbing and includes a 1.5 mile climb that ascends 650 feet.

This is a slow-paced ride designed for the beginner-intermediate rider that has experience riding on climbing/descending trails and wants to further develop their bike riding abilities. This ride can also be enjoyed by more advanced riders looking for a relaxed ride in a beautiful setting. Motorized recreation vehicles of any class or type are not permitted for use in the Nature Preserve.
