Hi @Ronald ! REI Anchorage does stock the Annual National Parks pass that covers all US National Parks for a year. If you’re going to multiple parks or want one that’s valid for a year, this is a great option. When you get a little closer to the date, feel free to order online (rei.com), and pick it up in the store. It’s ready in about 2 hours, and we hold it for up to 2 weeks.
At Denali National Park, they have passes that are good for a week or a year for that specific park as well. The info for that is on this website under Fees. https://www.nps.gov/dena/planyourvisit/basicinfo.htm
Here is the pass REI sells:
