Vote for Your Favorite U.S. National Park

The National Park Service celebrates its 100th birthday in 2016, and TIME is marking the milestone by publishing Our National Parks at 100. We know you love the parks: a record 307 million people visited them last year, from the depths of the Grand Canyon to the peaks of the Great Smoky Mountains. Now we want to hear from you: vote for your favorite park, and we’ll publish the results in our forthcoming book, which will be gorgeous, informative, and, yes, partially crowd-sourced.
