Irvine Ranch Natural Landmarks

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.
