This map contains most of the National Park Service units that I have visited. I have omitted most of the national trails. The map is interactive. Click one the colored circles to zoom in and hover your cursor over a pin to see the name of the site. I’ve colored coded the sites to reflect their classification. To date, I have visited a total of 146 National Park Sites.

The GitHub repository, which contains the raw data and code necessary to reproduce this map, is located here.
