The preserve attracts people with its natural beauty and abundant natural resources, both today and in the past. It is characterized by varied natural resources, including over 500 plant species, more than 175 types of birds, and a great variety of reptiles, amphibians, and mammals.
The canyon and its tributary are home to a year-round stream populated by Pacific tree frogs, crayfish, and largemouth bass. Additionally, mule deer, bobcat, coyote, and raccoon are just a few of the mammals that can be observed throughout the preserve.
The area has a rich Native American history dating back as far as 7,000 years ago. Remains of the prehistoric culture can still be found. The area was also part of the first Mexican land grant in San Diego County, and features a restored historic adobe that offers tours.
Volunteers are always welcome to help with the maintenance and operation of the park. Park Rangers also offer interpretive walks and programs for those interested in learning more about the preserve.
