Graywolf camp and Three Forks camp are right next to one another. Both have plenty of space and sit at the confluence of the Gray Wolf River, Cameron Creek and Grand Creek. Permits are required here as it resides in Olympic National Park land (look to Camp Tony in USFS land of you forgot a permit) but I was there right after 4th of July and didn’t see anyone at either camp. Privy is there although bring your own TP and strong stomach. Three Forks also has a shelter for bad weather days and general chilling. Hike in is about 8.5 miles from Gray Wolf trailhead.
