Obamas Visit National Parks: Send Us Photos Of Your Favorite National Park

Last week, we had a great time checking out the beautiful and amazing national parks across the country with our Top 10 Best National Parks You Haven't Heard Of. And wouldn't you know it, this week, the Obamas are visiting a few gems to promote the nationwide no fee park weekend August 15-16th.

So in the spirit of park enthusiasm, we'd like YOU to tell us about your favorite parks, and send us your photos of national parks you've been to.

Here's how it works:

Hit the participate button, leave your description and mark the area of your favorite park by searching for an address in the box on the top right of the map, upload your photo and hit submit. Thank you!
