National Park Week is America's largest celebration of national heritage. It's about making great connections, exploring amazing places, discovering open spaces, enjoying affordable vacations, and enhancing America’s best idea—the national parks! It's all happening in your national parks.
The National Park Service just turned 100 years old! Celebrate by visiting a park in 2017. During ten days of the year, all National Park Service sites that charge an entrance fee will offer free admission to everyone.
