The park is located along the Stanislaus River near the town of Ripon, California. The park protects a fine example of the threatened and still declining riparian oak woodland, which once flourished throughout California's Central Valley. Caswell is home to several endangered animal species, including the riparian brush rabbit which is not known to occur anywhere else. Several species of fish including bass, catfish, crappie and more await your most enticing fishing technique. Campfire programs, Junior ranger programs and nature walks are given every weekend throughout the summer. Interpretive walks and talks for school, service and social groups are available by making prior arrangements with park staff. The Stanislaus River meanders through the park, with beaches and swimming areas near the park’s day use and campground facilities. One of the most magnificent aspects the park has to offer is its seemingly endless nature trails. The trails allow a glimpse of what the riparian ecosystem of the valley would have looked like in pristine times. A majestic Oak Forest is surrounded by many other lush plant species, some of which are rarely found anywhere else in the area. The park offers a rich variety of wildlife viewing. While many of the wildlife species here are nocturnal and rarely seen, bird watching is a favorite among nature lovers. Red shouldered and red tailed hawks are often seen, along with dozens of other winged artists.
