For cyclists and hikers … don’t worry if it says ‘Campsite Full’ out on the road- it does have a hiker/biker campsite, with food storage, picnic tables, and fire pits. It’s right behind the reception building and they offered to charge up electrical items at no cost. An offer of coffee in the morning as well. Close to the road which is super busy in the day, but almost no traffic at all throughout the night. Very helpful staff in the reception building. Small camp store selling some basics. A day trip to Old Faithful is an option from this campsite
