Caswell Memorial RV & Campground Guide


Caswell Memorial State Park was the brainchild of Thomas Caswell, who owned the property prior to 1950. In that year, the park's 134 acres were donated to the State of California by Caswell's children and grandchildren in accordance with his wishes. Caswell Memorial State Park is in one of the last riparian oak forests in the Central Valley in California. It's declining, but conservation efforts are ongoing.

Although both Caswell Memorial State Park and its accompanying campground are currently open, the area is under an ongoing warning for "summer branch drop." That means that otherwise healthy, mature trees can suddenly have their branches fall off. Exercise caution when hiking and avoid any camping spots under mature trees. Contact the park for up-to-date information.

What to Do at
Caswell Memorial

Swimming is one of the most popular activities at Caswell Memorial State Park, particularly in the searing heat of summer. Tubing is also a fun way for you to cool off with your family. Boating, too, is popular, and you can set off from the boat launch at the north end of the park's campground. Hikers will find the nature trails easy and relaxing.

As with most state parks that lie next to bodies of water, it's water-based activities that people most enjoy.

Inside Caswell Memorial

One of the highlights of Caswell Memorial State Park is the trail network — with short and long routes, it’s easy to find a hike for families or experienced trekkers. Wander next to the river to enjoy the cool breezes, or head into the oak forest for a calm, shaded walk. If you’re visiting in the warmer months, cool off with a dip in the Stanislaus River. Fish for bass and catfish during the day, and check the park schedule to learn about the ranger-led nature walks and campfire programs. Be sure to bring your binoculars as the bird-watching opportunities in the park are exceptional.

Hiking Hiking

The three nature trails range in length from 0.8 miles to 3.7 miles. They're flat trails that wind through the oak forest. Remember to watch for suddenly falling branches.

Stargazing Stargazing

Although Ripon is only 5 miles away, the trees provide some cover from the light pollution, allowing you to set up your telescope and observe the heavens. If your campsite adjoins the beach, then lying on the sand and looking up is also good for stargazing.

Flora and Fauna

Bears don't roam the Central Valley as much as they did 100 years ago, but there are still black bears occasionally. That's the reason for the food lockers! Also, you'll find reptiles like the southern alligator lizard and the gopher snake. There are also many varieties of birds, such as the barn owl, turkey vulture, and great blue heron. The luckiest of visitors might catch sight of "Lupine," or California Condor #597, soaring high on his 10-foot wings. There might be 60 condors living in the Central Valley, so keep your cameras pointed skyward for these magnificent creatures.

Geocaching Geocaching

There's a geocache on one of the trails in Caswell Memorial State Park.

Fishing Fishing

The Stanislaus River contains crappie, both common kinds of bass, and catfish. Sometimes, multiple species of trout join the party. Rarely, you might also be able to hook a salmon or carp exploring upstream from the junction of the Stanislaus and the San Joaquin River. You can fish 10 months out of the year, with November and December off limits for stocking and spawning.


Most of the boating on the Stanlislaus River is restricted to boats with no motors. In some sections of the river, you may use motors of 10 horsepower or less. Contact the park to ask for further information.

Swimming Swimming

Occasionally, the river will be unsafe for swimming. On days when the water's at safe levels and speed, swimming is a terrific way to cool off from the summer sun. Riding tubes on the river is also popular. There are no lifeguards on duty, so young children and non-swimmers are required to wear lifejackets when in or near the water.
