How we rank
Crowds, not weather
Every number here is National Park Service recreation visits, averaged by calendar month over 2021–2025. A park’s crowd index compares each month with its own busiest month (100). Peak season is 80 or above; shoulder months border the peak and still reach 30. We rank shoulder months quietest first.
We don’t score weather, and a quiet month can be quiet because of it. The crowd calendar has the full method and every park’s twelve months side by side; each park page links to its nps.gov conditions.
