Glad Bob mentioned the permit. I just spoke to Steve at the Hobuck Resort and the permit can be purchased there. Also Camping and permits can be paid for by check, cash, visa/discover credit cards..
"There is no admission cost to hike the trail, but you do need to purchase a Recreation Permit upon entering the reservation. These can be purchased at the Makah Marina, Washburn's General Store, Makah Tribal Center, Makah Mini Mart and the Makah Museum, . They cost $10 per car and are valid for the calendar year in which they are purchased".
