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.

This docent-led ride kicks off at the historic Bommer Canyon Cattle Camp, where we’ll climb the West Fork Trail to the top of Bommer Ridge. Take in sweeping panoramic views as you catch your breath—this is just the beginning.

From there, we’ll flow over to Lizard Trail, riding through lush riparian habitat before a short climb brings us to Serrano Ridge. Enjoy a fun descent down Camarillo Trail as we make our way to the Nix Nature Center for a quick water refill and reset.The adventure continues with a mix of rolling climbs and rewarding terrain as we make our way to the Cattle Crest trailhead.

From there, we’ll ride Cattle Crest into Shady Oaks—both offering a fun blend of challenging downhill singletrack and short, punchy climbs to keep things exciting.
After one final push out of the canyon, we’ll reach the gate to Hogback—your gateway to one of the most fun, flowy singletrack descents in Orange County. We’ll finish with the exhilarating Ridge Route, a fast, flowing ride back down to our starting point.

Expect great trails, stunning views, and a supportive group atmosphere. Whether you’re looking to challenge yourself or simply enjoy the ride, this is an experience you won’t want to miss. This intermediate-paced ride is designed for experienced riders who are in excellent physical condition and comfortable on challenging singletrack terrain. Expect a rewarding 15-mile route with approximately 3,000 feet of elevation gain, featuring a mix of sustained climbs, exhilarating descents, and a few technical sections where riders may choose to walk their bikes.
