About George Hatfield Group Campground
Escape the crowds and discover a hidden riverside sanctuary where the gentle Merced River winds through ancient groves of oak and box elder trees. This tranquil campground invites adventurers to cast a line into crystal-clear waters, pitch their tent beneath a cathedral of branches, or simply float away an afternoon in the river's cooling embrace. Whether you're hiking secret trails, studying the diverse wildlife, or gathering for a riverside picnic, this peaceful retreat offers authentic outdoor experiences far from the beaten path.
The campground primarily caters to group camping but also allows primitive and RV camping. Tent camping and ADA-compliant sites are available.
Historical SignificanceWalk in the footsteps of history at this remarkable site, generously gifted to the public by George J. Hatfield, California's distinguished former Lieutenant Governor and State Senator. Long before Hatfield's generous donation transformed this land into a public treasure, the Yokut people thrived along these riverbanks, establishing villages that connected them to the life-giving waters of the Merced. Today, visitors can sense the deep cultural heritage that permeates this special place, where centuries of human connection to the land continue to inspire.

ElevationNestled in the heart of the valley floor, this campground offers easy accessibility and gentle terrain perfect for all ages and abilities.
Natural Features and SceneryImmerse yourself in a living tapestry of California's native ecosystem, where towering valley oaks create natural amphitheaters and box elders whisper ancient stories. The rich, sandy bottomland nurtures a paradise of wild edibles - from sun-warmed elderberries to tangled blackberry thickets and grape vines that drape like nature's own decorations. Cottonwoods provide dappled shade along meandering paths where curious raccoons, elusive weasels, and playful otters make their homes. Bird enthusiasts will delight in the seasonal parade of migratory species, while evening brings the gentle rustling of opossums and the occasional glimpse of a muskrat gliding through the water.
Geological RegionDiscover the natural abundance of the San Joaquin Valley, where millennia of river deposits have created extraordinarily fertile sandy soils. This riparian wonderland along the Merced River represents one of California's most precious ecosystems - a ribbon of life where water, earth, and sky converge to create an oasis of biodiversity in the heart of the great Central Valley.
