Williams Grove Group Camp is a single group campsite within Humboldt Redwoods State Park that accommodates up to 60 people and 18 vehicles, making it ideal for organized groups like scout troops and family reunions.

Located along the Avenue of the Giants just half a mile north of Myers Flat, the camp sits directly on the South Fork Eel River with immediate access for swimming, fishing, and wading, plus a seasonal summer bridge connecting to extensive backcountry hiking trails.

Basic amenities include picnic tables, fire rings, flush toilets, and tap water, though there are no showers on-site, no electricity, and no RV hookups; reservations are available up to six months in advance and the campground operates seasonally from Memorial Day through Labor Day.
