The Park Store is operated by Western National Parks Association. As you might find out once you arrive at the visitor center, the park store is gone! Where did it go? Well, walk on over to the trading post and inside to the right, there is the park store. Items can be purchased along with your groceries.
Do not forget to ask for your membership to Western National Parks Association. You can get 15% off your park store purchases that same day.
