Equestrian Ride: Discover The Natural Wonders Of Weir Canyon

Be prepared to experience the beauty and wonder of Weir Canyon, part of OC Parks’ Irvine Ranch Open Space, steeped in history and lore, on this morning equestrian ride. The ride will travel through Weir Canyon, where the trail weaves its way through a beautiful oak woodland inhabited by deer, coyote, bobcat, and many different birds. You will travel the route of the Butterfield Stage and see a monument dedicated to the Mexican ox cart drivers. If time permits, we will climb to the Two Tower vista point to look at distant views. This ride travels on wide trails with several easy to moderate climbs. Equestrians who have trail riding experience and their own fit and able horse are welcome.

Tuesday Morning Fitness Hike on Paved Hicks Haul Road

Ready for a workout? Forget the gym for the day and head outside! Join us for an exhilarating morning fitness hike on the paved Hicks Haul Road in OC Parks’ Irvine Ranch Open Space. This hike allows you to choose between a 3, 6, or 8 mile route, all of which are conducted at the speed of about 3.0 to 3.5 miles per hour. The footing on the asphalt paved road is smoother than dirt roads and single track trails normally found in Limestone Canyon Nature Preserve, but is beginning to show its age with cracks, crevices and an occasional dip. Otherwise, the terrain is smooth, so this is a great walk for anyone who wants a “wilderness experience” without getting dirty! The 6 and 8 mile routes experience two fairly steep ascents and descents. The 3 mile route takes you to the top of Loma Ridge and back down. Along the way, you will have sweeping views of much of Orange County and the Santa Ana Mountains. Various animals, like hawks, deer, and lizards are also frequently seen in this area.
Open Space Invaders: Invasive Plant Removal at Silverado

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.
