We are a couple with two boys (ages 7 and 5) living in Seattle. We came to Seattle in 2008 to study at the University of Washington and since then have fallen in love with the natural beauty of the area and enjoy exploring the many beautiful sites around Washington state and national parks in the US. From Yellowstone National Park, the first national park established in 1872 to Pinnacles National Park, the most recent one designated as a national park in 2013, there are 59 national parks in the United States. We would like to share our experience at each park for families like us planning to visit national parks with young kids. Mount Rainier National Park is the first national park that we have visited. Previously we only made day trips to the park 2 to 3 times each year, but in the summer of 2016 we stayed near the park for 5 days and explored many of the park's attractions. In this book, we have organized a summary of our family's trip including a brief journal of our journey, information that we researched before the trip, tips that we realized would be good to know and pictures. Because this trip is focused on travelling with young children, the difficulty level is mostly based on 'easy' courses with a couple of 'moderately challenging' attractions. Therefore, regardless of the size of your family or the ages of your children, it is simple to think of the attractions in this book as a trip that a five-year-old enjoyed.
