McHenry Avenue Campground is part of the park system scattered along the lower Stanislaus River within the foothills of the Sierra Nevada. The environmental campground boasts quiet, peaceful tent sites situated close to the river’s edge. The scenic recreation areas and river access points are popular for activities such as rafting, picnicking, hiking and much more. Stanislaus River Parks is often referred to as the “string of pearls” since they serve as charming, quiet oasis running through a number of small towns and cities.
The campground offers an excellent base camp for exciting recreation opportunities. The park boasts walking and hiking trails, picnic areas and river access points for fishing and boating.
McHenry Avenue Recreation Area Campground is one of three reservable campgrounds in Stanislaus River Parks’ system. Its amenities include flush toilets and potable water near the campsites. Each campsite contains a picnic table, fire ring, and a lantern holder. Campers must park their vehicles in the campground parking lot. No vehicles are permitted at campsites.
The campground scenery is a pleasant mix of Fremont cottonwoods, Valley Oaks and the occasional elderberry bush, offering sporadic shade with dispersed rays of sunshine. Nearby, grasses, shrubs and seasonal wildflowers fill the open spaces.
Wildlife is also plentiful in the park with mule deer, acorn woodpeckers, scrub jays, foxes and squirrels among lots of other fauna.
Within 35 min drive, campers can explore the historic town of Knights Ferry, rich with history of the gold rush era.
