Shadow Cliffs Regional Recreation Area



  • Directions

  • Size

    259.19 acres


A haven for swimming and fishing can be found at Shadow Cliffs, only a mile from downtown Pleasanton on Stanley Boulevard.

Shadow Cliffs, formerly a gravel quarry, was donated to the Park District by Kaiser Industries and opened as a park in 1971. Its assessed value of $250,000 was used to obtain a matching grant for development of the park from the U.S. Bureau of Outdoor Recreation.

With this start, the Park District has developed a 266-acre park including an 80-acre lake and ample parking and picnic grounds. There are facilities for persons with disabilities.

Besides the main lake, Shadow Cliffs has an arroyo with a chain of smaller lakes and ponds. No swimming or boating is allowed here; the shady areas and quiet waters make for a peaceful retreat on hot summer days.

Additional Information

Accessibility Description

Shadow Cliffs offers wheelchair accessible parking, trails, picnic tables and restrooms. A wheelchair accessible fishing pier is located near the boat launch and can be reached by paved trail. The bathhouse is also accessible to wheelchair users.

Beach wheelchairs, intended to provide a means for wheelchair users to travel across the beach, are available for free, on a first-come, first-served basis. They require an assistant to push and are not intended to enter the water. To arrange for use of a chair, call the Shadow Cliffs lifeguards at (925) 484-1986. A staff member will bring the chair out to the beach. It takes approximately 15 minutes to prepare the chair. Staff will give a brief orientation to the chair and arrange a time for the chair to be returned.
