The next park in the list from my Alaska trip is Kobuk Valley. Also above the Arctic Circle, this park is incredible mostly because of the uniqueness of the Sand Dunes. The nice thing about this park was being able to stay in the same camp for a few days in a row. Not having to break down camp every day makes a huge difference! It allowed me to get up early to see sunrise, which from the top of the dunes by camp was beautiful:
