Terms of use

By using Park Crowd Calendar, you agree to the following. We've kept it short and plain.

Informational use only

Park Crowd Calendar is a trip-planning aid. Crowd scores describe how busy a park tendsto be in a given month based on historical data; they are not a guarantee of the conditions you'll encounter. Use the site to plan, not as your sole source of truth for a specific date.

Not affiliated with the NPS

Park Crowd Calendar is an independent project. It is not affiliated with, endorsed by, or sponsored by the U.S. National Park Service, NOAA, or any government agency. Park names and public data are used for informational purposes.

Always verify before you travel

Conditions change. Road and trail closures, permit and reservation requirements, fees, hours, and safety alerts can all differ from what you see here. Before any trip, confirm the current situation with the park directly at nps.gov.

No warranty on accuracy

We work hard to source our numbers faithfully from public datasets (see our data sources), but we make no warranty that the information is complete, accurate, or current, and we accept no liability for decisions made based on it. The site is provided “as is.” If you spot an error, please let us know.
