Grassy Flat Campground offers 19 primitive tent and RV sites with vault toilets and picnic tables directly above the Middle Fork Smith River, providing immediate access for swimming, fishing, and rafting.

A trail leads down to the river for water recreation, and the campground is located in Six Rivers National Forest along Highway 199, about 18 miles east of Highway 101 near Crescent City.

Sites are spacious and well-separated by trees, though water availability may be intermittent and there are no showers or hookups; camping costs $10 per night.
