August marks the last days of summer. It’s one of the busiest months in the United States. The schools are opening, and everyone wants that final trip to wrap up the summer season. So, many national parks are too crowded and very hot during summer.

At first glance, August may not seem like an ideal month to visit many national parks in the United States. However, there are so many places with fewer crowds and more favorable temperatures at this time of the year!

This article provides a curated list of various national parks that you can visit in August. From the jaw-dropping wildlife at North Cascades National Park in northern Washington to the surreal terrains of Denali National Park in Alaska– everything you’ve been looking for is on this list!
