It may be a chilly time of the year to visit many national parks, so check the weather in your location. Here in California, there are 25 national parks to choose from. You can find a listing of the parks and relevant details near your location by searching the National Park Service website. And if you check out one of the parks, send us a picture and we might feature it in an upcoming post.
Of course, before you go, check out the National Park Service website for the details of what the fee waiver includes. Safe travels!
