Grassy Flat Campground Access and Parking Area provides vehicle parking and trailhead access to the Middle Fork Smith River in Six Rivers National Forest, located 18 miles east of Crescent City on Highway 199.

A short trail from the campground leads to river access with swimming holes and small gravel beaches, while nearby Madrone Flat offers easier flat parking and access to a large sandy beach and shallow swimming area.

The facility operates seasonally (typically May-September) with vault toilets, picnic tables, and fire rings available, though no water is provided on-site.
