CANCELLED due to Trail Conditions: Slow-Paced Mountain Bike Ride: Fremont and Weir Nature Preserves

Mountain Biking

Enjoy riding in the wilderness on empty trails when you join us for a docent led mountain bike ride that loops through Fremont, Blind and Weir Canyons. The ride will stop several times along the way to rest and regroup, and will take in expansive views and the flora and fauna of the Fremont Canyon and Weir Canyon Nature Preserves. If you are very physically fit and in excellent cardio shape, this is a great opportunity to enjoy this seldom visited wilderness of Orange County!

The ride starts in Irvine Regional Park, but quickly enters Fremont Canyon Nature Preserve. We will first stop at the weather station atop Windy Ridge from which there is a 360 degree view of Orange County and the surrounding areas. The ride then heads down into Weir Canyon Nature Preserve, which consists largely of oak woodlands and is one of the best places to see wildlife in the local area. We will then ride the enjoyable Weir Loop in neighboring Santiago Oaks Regional Park before returning to our starting point via Weir Canyon.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-4 activity on the land. Electric Mountain Bikes of any class or type are not permitted.

This is a slow-paced ride designed for the beginner to intermediate rider who is in excellent cardio shape and is physically fit, but sometimes needs to move slower on steep ascents or descents. We will ride both fire roads and largely non-technical single track trails (note the Weir Loop has a couple very short technical sections). This ride has climbs with some steep sections that may be ‘hike-a-bike’ for some riders. The ride will regroup and rest as needed and an opportunity will be provided for a snack break.

Please note, the ride is approximately 17 miles long with 2000 feet of elevation gain.

This activity originates and ends in Irvine Regional Park and travels into OC Parks’ Fremont Canyon Nature Preserve, Weir Canyon Nature Preserve and Santiago Oaks Regional Park.
