I have loved visiting national parks since my parents took my sister and I to places like the Grand Canyon and Carlsbad Caverns while on family vacations when we were kids. With 62 parks available across the country, there are always new adventures waiting to be had, and you don’t even have to travel outside our nation’s borders to enjoy them. The only problem is knowing where to go and what to do once you’re there. That’s when the ninth edition of National Geographic’s Guide to National Parks of the United States becomes an invaluable resource.
