NPS Centennial

The National Park Service turned 100 on August 25, 2016, and we're celebrating all year long! Throughout 2016, we invite you to participate in Find Your Park Experiences to learn, discover, be inspired, or simply have fun in national parks. Find Your Park Experiences offer unique opportunities to explore national parks both in person and online. Check out the experiences in this park or search all experiences to identify an opportunity that matches your interests. You can also share your national park story at
