Sunset Mountain Bike Ride In Weir and Fremont Canyon Preserves

Think you would enjoy a challenging but relaxing evening biking in the wilderness on empty trails with both a sunset and a nice view of city lights, then join us on this summer time ride through Weir, Blind and Fremont Canyons, part of OCParks’ Irvine Ranch Open Space. This ride is for experienced off-road riders, in excellent cardio shape, that have some experience with evening/night riding.

Please review the 1-through-5 Difficulty Ratings to help you evaluate your readiness to participate in this program. This program has the distance/elevation of a level 5 program, but the ride time can accommodate a slower pace. Motorized recreation vehicles of any class or type are not permitted for use in the Nature Preserve. Please visit our FAQ page for answers to activity specific questions you may have prior to registering.

The route exits Irvine Regional Park and goes into Weir Canyon. We will ride Weir Canyon Road and Upper Blind to the Fremont Weather Station. Depending on timing and trail conditions, we may ride on the new Overlook Trail in Weir Canyon or go out Windy Ridge past the Fremont Weather Station. We will return in twilight/night to Irvine Regional Park on the fast descent to the Fremont Staging area. The ride will regroup mid-ride and just prior to the final descent to the staging area. If needed, the route described could be ridden in the opposite direction.

Please note, the ride is 12 to 15 miles long, with approximately 2000-2500 feet of elevation gain. There are some steeps sections on the climbs that might be hike-a-bike for some riders. It is important that participants bring enough food and water for a ride of this length and the weather conditions. This program originates at the Outdoor Education Center Staging Area in Irvine Regional Park and ventures into the Weir Canyon and Fremont Canyon Nature Preserves.

Please note that you will be asked to adhere to the following measures during the activity in order to participate:

  • Be registered in advance, no walk-up registration is permitted.
  • Arrive with all necessary equipment to keep you safe on the trail, including water, proper attire, and closed-toe footwear, first aid, health needs etc.
  • Restrooms will be available, but facilities will not be sanitized for each individual.
  • You may be prevented from participating if you do not adhere to the above protocols.

Additionally, in an effort to respect and protect all employees, volunteers, and participants, please do not sign up or attend if you are not feeling well, exhibiting any symptoms of illness or have been in recent contact with someone who was ill.
