Structures & Facilities to Support Your Visit

The National Park System includes more than 400 parks across the country, covering more than 85 million acres. These diverse sites contain historic buildings, battlefields, recreation facilities, monuments, trails, and roads along with significant natural and cultural resources. This unique infrastructure has evolved over time in response to the National Park Service mission. Maintaining that infrastructure is a key responsibility of the National Park Service.

Learn how we manage our infrastructure to enable visitors to experience national parks in a safe and accessible environment and to enhance their park experience.
