Mount Rainier National Park campsites, sold out? Here's how spots come back.

How booking at Mount Rainier National Park works

Reservations for Mount Rainier National Park are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.

Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.
