Caswell Memorial
RV Guide


The Stanislaus River and surrounding oak forests make Caswell Memorial State Park one of California’s most pristine examples of a riparian forest ecosystem.

Visitors to the park can enjoy 258 acres of protected lands that are home to a variety of wildlife, several species of which are endangered. The area is especially popular with bird watchers eager to catch a glimpse of hawks, owls, and water fowl.

Take advantage of the river’s cooling waters by swimming at one of two designated swim beaches or canoeing, kayaking, and tubing down the waterway as it winds through the park.

The Stanislaus River is also a favorite of fisherman who catch bass, catfish, bluegill, and, at certain times of year, migrating Chinook salmon.

Hikers of all skill levels can find a nature trail made for them in Caswell Memorial State Park’s extensive trail system. Call ahead to arrange for a Ranger-led hike to learn more about native wildlife, plants, and park history.

The Caswell Memorial State Park Campground offers 64 family campsites each with a picnic table, camp stove, and food locker. Visitors can easily access hot showers, restrooms, and the beach.

On a hot California day, nothing is better than a dip in the cool river waters. Caswell Memorial State Park has two designated swimming areas. The first, Salmon Bend Camp Beach, is located adjacent to the campground. The second, Willow Beach, is located in the Day Use area. No lifeguards are on duty. Park rangers caution visitors to wear life jackets while in or near the water at all times as water levels in the area can change quickly and unexpectedly.


The Stanislaus River provides the perfect venue for experiencing Caswell Memorial State Park and getting an authentic taste of the park’s unique natural surroundings. Only small, hand-powered watercraft are allowed. Canoes and kayaks are a local favorite, and can be rented in the area if you don’t bring your own from home. Many guests choose to tube the river as well. A hand boat launch can be found in the Willow Beach Day Use Area and at the Salmon Bend Camp Beach.


The Stanislaus River winds through Caswell Memorial State Park. The slow-moving, muddy-bottomed river is a favorite fishing spot for anglers of all skill levels. Many species of fish thrive in the area. On any given summer day, fishermen can catch largemouth, smallmouth, and striped bass, sturgeon, bluegill, catfish, shad, and buffalo carp. Chinook salmon migrate annually through the area. Walk directly from the campground to the water’s edge or set up for the day anywhere along the shore.

These nature trails offer an experience for all ages, and deliver an up close and personal look at the valley’s riparian ecosystem.

Visitors can tackle short segments of trail or travel the entire connected trail system through oak forests dotted with rare plant species. Except for service animals, pets are not allowed on the trails.

Wildlife Watching
