Activities and Programs

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 ride to Mini Moab in Fremont Canyon, a part of OCParks’ Irvine Ranch Open Space. Mini Moab is located at the top of Coal Canyon above the 91 Freeway; this spot provides views of the Fremont Canyon Wilderness as well as Orange and surrounding counties. 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.

Non-native and invasive plant species are invading our native habitat and open spaces. They aggressively compete with our native plants for resources and spreads rapidly once established. Monitoring, management, and removal of these plant species is an important aspect of land management and habitat restoration.

Help us to manage populations of invasive plants and remove them from the habitat. No previous experience is necessary, just a desire to work outside and get dirty! Snake chaps, gloves, and tools will be provided but please feel free to bring your own if you have them. Please wear long pants, long sleeved shirts, close toed shoes, and protective sun protection. Note: This is a wilderness area, there are natural hazards. Snakes, including rattlesnakes, are occasionally seen here.

Join us in OC Parks’ Irvine Ranch Open Space for a challenging docent-led mountain bike ride for very experienced off-road riders in excellent cardio shape through Fremont and Weir Canyons to Sierra Peak.

We will climb out of Irvine Regional Park on Coal Mine Road to the Fremont Canyon Weather Station and then continue on past the Tecate Cypress grove, Lizard Rock and Mini-Moab on the way to Sierra Peak . We will return to the staging area via much of the same route but will finish by riding through Upper Blind Canyon to Weir Canyon.

Come enjoy an early morning hike in Fremont Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space. Our hike climbs steeply from the mouth of Fremont Canyon, past an abandoned coal mine up to the Fremont Weather Station where winds have been clocked at up to 100 mph. After enjoying the view, we’ll hike back the same way to our starting point. This hike involves steep hills and a 1200’ elevation change but the rewards are panoramic views of Orange County, the Santa Ana Mountains and surrounding areas as well as possible wildlife sightings. Please arrive 15 minutes early; the entrance gate will be shut and locked 5 minutes before start of the activity. Be sure to come prepared with a sturdy day pack, water, snacks, closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail.
