National parks in Washington state: 7 hidden treasures you should know about
We love these national parks and we think you will, too
Mount Rainier, Washington state

Washington state is, without a doubt, one of the prettiest corners of America. I admit, I'm totally biased, having been stationed here for about two years from the scorching state of Arizona. Don't get me wrong, the desert definitely has its charms, but I've always been a pine trees, waterfalls, and green mountains kind of gal, so when we moved up here, it honestly felt like heaven.

During the past couple of years, my husband and I have discovered so many jaw-dropping NPS sites, from Mount Rainier to the Cascades, and I can't wait to share some of our favorite treasures. Some of these spots will be famous and well loved, and others are definitely ones that should be in the spotlight.
