Oso Trail Professional Reviews and Guides
"Pick a clear, cool day, and set aside the better part of it for this hike to one of the highest ridges in Caspers Wilderness Park. You’ll have a wonderful view of the higher Santa Anas, the Los Angeles Basin, the San Joaquin Hills, and the ocean. You’ll return along San Juan Creek, meandering in and out of the shade of oaks and sycamores."
