National Park Visitor Board Screensaver
The National Park Visitor Board screensaver ranks U.S. national parks by real published annual visitor counts on a bar board, drawn from the National Park Service's own visitation statistics. It's free, runs in your browser, and ESC exits.
How the National Park Visitor Board screensaver works
Parks rank top to bottom by real published annual visitor counts.
Each bar is sized to scale against the most-visited park.
Figures are real NPS visitation statistics, updated periodically as new annual totals publish.
This is real reference data, not a live tick-by-tick feed — visitor counts are tallied annually, not in real time.
A worked example
At the top you'll typically see parks like Great Smoky Mountains and Zion drawing real millions of annual visits — genuine NPS-recorded figures, not estimates.
Settings & tips
- Accent recolours the bars.
- The NPS's live developer API covers park metadata, not visitation statistics — this uses their published annual figures instead.
- Great Smoky Mountains has led U.S. national park visitation for decades, a real and consistent pattern.
Frequently asked questions
- Is this a live feed?
- No — visitor counts are tallied annually by the NPS, not published in real time, so this uses their real published annual figures, similar to the site's Oil Rig Count.
- Is a key needed?
- No — it uses real published reference data with no live fetch.
- Where does the data come from?
- The National Park Service's own published annual visitation statistics.
- Is it free?
- Yes — free, no download, in your browser.
