Willow Creek Environmental Campground offers 11 primitive walk-in tent campsites (within 1/4 mile of parking) along the Russian River with fire rings, picnic tables, and vault toilets, making it the only state park campground directly on the Russian River.

The campground is first-come, first-served with no reservations, no running water, and requires cash or check payment; sites are shaded by willows and close to a large beach suitable for swimming and fishing.

Access is via Willow Creek Road off Highway 1 near Jenner, and the campground typically operates mid-March through mid-October with no dogs allowed to protect wildlife.
