Here’s an interesting page on the economic impact of visitation to our National Parks. 

Visitor Spending Effects – Economic Contributions of National Park Visitor Spending

This interactive tool is a collaboration between the National Park Service and the U.S. Geological Survey and displays results from the Visitor Spending Effects report series. Economic contributions of National Park Service visitor spending are displayed at the national, state, and local levels.
