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 OCParks’ 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.

By removing invasive weeds, we will ensure the Big Canyon project site thrives with native plants for years to come. No prior plant ID/weeding experience necessary.

Minors must have a legal guardian present at all times.

Experience the wonders of two preserve areas located on OCParks’ beautiful Irvine Ranch Open Space, Fremont and Weir Canyons. We begin our equestrian ride atop the Waterworks trail, an old filled-in V ditch that served to water the vast acres of the old Irvine Ranch of Orange County. We parallel Santiago Creek and enter the mouth of Fremont Canyon where native flora and fauna abound and find refuge from the sprawling urban environment. We turn and head toward Weir Canyon along the MWD trail and find ourselves gaining elevation and on little hills. As we head into the canyons we find hawks overhead and the coastal sage scrub turn into chaparral. We may find wildflowers or native grasses sprouting and certainly, we will hear sounds from Irvine Park. Serenity will be found as we enter the quietness of Weir Canyon where Oaks abound and restoration continues where Ox carts once traversed. After travelling back in time, we make our way back to the park and toward our original starting point going through Lower Weir Canyon and back into the park.
