In the agency’s own words

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. Keep reading

Recreation

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.

Facilities

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.

Natural Features

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.

Nearby Attractions

Within 35 min drive, campers can explore the historic town of Knights Ferry, rich with history of the gold rush era. Within the historic district, lies Knights Ferry Recreation Area, home to the longest covered bridge west of the Mississippi River and a National Historic Landmark dedicated in 2014. The park boasts walking and hiking trails, picnic areas and river access points. Visitors can learn about the area when they visit the Knights Ferry Visitors Center, which contains a small museum highlighting local, natural, and cultural resources. Visitors have a unique opportunity to make reservations with local rafting companies to journey down the Stanislaus River. During the summer months, rafters can enjoy guided and self-guided floats down the lower Stanislaus River. For thrill seekers, the fall season brings perfect flows for advanced white water in the Goodwin Canyon. Fall also brings thousands of Chinook salmon returning to the Stanislaus River to spawn, completing and beginning their lifecycles. Onlookers, can view the spawning salmon from several river access points along the river.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

OpenStreetMap has no toilet mapped within 1 km of this campground, so no site here carries a toilet distance. That’s a gap in the map, not a finding about the campground.

How we know

every fact on this page, and where it came from
Right now: U.S. Army Corps of Engineers publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Cell signal: the Army Corps’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
