Irvine Ranch Natural Landmarks

Join us for an evening/night mountain bike ride through Limestone Canyon Nature Preserve and Red Rock Wilderness, part of OCParks’ Irvine Ranch Open Space. We will ride approximately 12 miles, with 1500′ of climbing along a variety singletrack trails and ranch roads. The route will vary based on trail conditions/availability.

This ride is not recommended as a first time night ride. Bring adequate lights, a jacket, plenty of water, spare tubes, tools and all other equipment to be self-sufficient on the trails. Hopefully we will see some of our local nocturnal critters. Motorized recreation vehicles of any class or type are not permitted for use in the Nature Preserve.
