Happy birthday, Mount Rainier National Park! Established in 1899, our 5th national park has been amazing visitors for 119 years. Home to the tallest mountain in Washington, the park is a wonderland of history, wildlife and natural beauty. Gorgeous in every season, there’s nothing quite like the park’s summer wildflower blooms. Put this park on your bucketlist! Photo by Danny Seidman (www.sharetheexperience.org).
