From OC Parks:
…encompasses approximately 4,300 acres of riparian and oak woodland canyons, rolling grassland hills and steep slopes of coastal sage scrub and chaparral. The park is highlighted by scenic rock formations, including the beautiful Red Rock Canyon.
There are three intermittent streams: Borrego, Serrano and Aliso Creek meandering through the park, each hosting an abundance of wildlife. Remnants of the former cattle ranching days can be seen throughout the park.
Though 90% of the park burned in the Santiago Fire of 2007, the land is in the recovery process.
In our last trip we see two sets of deer, falcons overhead, ridiculously large squirrels, and we may or may not have been growled at by a mountain lion!
Definitely worth a trip.
