One of the touristy things to do in Washington state is to visit Mount Rainier in the summertime. I can remember my parents packing the family into the Station wagon and visiting Mount Rainier. Mount Rainier National Park is arguably one of the most popular national parks in Washington state. Back in 2023, Mount Rainier National Park had approximately 2.5 million visitors. (That's according to the National Park Service)If you decide you want to go visit Paradise Lodge, plan ahead for the trip.
