About Park Crowd Calendar

Every national park has a “shoulder season” — weeks when the scenery is just as good but the parking lots, trailheads, and shuttle lines are a fraction as full. The problem is that this information is buried in spreadsheets. The National Park Service publishes decades of monthly visitation counts, but almost nobody outside the agency reads them. Park Crowd Calendar exists to translate that public data into a simple, honest answer to one question: when is the least crowded time to visit?

Who it's for

It's for anyone planning a trip who would rather see a canyon at dawn in a quiet week than fight for a parking spot at noon in peak season — families working around school calendars, retirees with flexible dates, photographers chasing empty vistas, and locals deciding which weekend to make the drive.

Who runs it

Park Crowd Calendar is built and maintained by Sharon Ben-Moshe, its founder, who analyzes the underlying federal data and designs the crowd-score methodology. We are a small, data-focused project — not a travel agency and not a government body.

Honest positioning

We are good at one thing: analyzing federal visitation and climate data to tell you how busy a park tendsto be in a given month. We are not park rangers, and we don't have boots on every trail. For live, on-the-ground conditions — road closures, wildfire smoke, permit lotteries, and safety notices — we link you directly to nps.gov, the authoritative source. Always confirm current conditions there before you travel.
