Get a head start on exploring the area by booking one of our rental cars in Pleasanton. Once you’ve got your rental car, head for Shadow Cliffs Regional Recreation Area. This former gravel quarry opened as a community park in 1971, and features an 80-acre lake, small ponds, and places to fish, picnic, and go birdwatching. If you’d like to have a true Bay Area adventure, head about 50 miles west to San Francisco proper. There, you can roam the city at will; visit the San Francisco Zoo, check out Fisherman’s Wharf, or drive across the Golden Gate Bridge.
