August 28th marks the National Park Service's 99th Birthday, which also marks fee-free day so you and your family can visit any national park for free!

To get you started, we’ve provided 99 ways to enjoy the national parks on the 99th birthday of NPS (see below!) Parks are so much more than the majestic landscapes you might think of; they also protect and preserve our culture and history in urban areas and offer endless ways for families to get involved.

To celebrate the upcoming centennial of NPS in 2016, the National Park Foundation (NPF) launched their Find Your Park campaign to encourage everyone to get up, get out there and #FindYourPark.

We encourage you to share your favorite park with your family and friends on social media with #FindYourPark and get more info at FindYourPark.com. There’s something for everyone!
