Low months are not always the best months. January, February, March, April, November and December each draw under 4% of the year's visits. That usually reflects snow, closed roads or reduced services, so check the park's own conditions page before planning around them. The quietest month overall is November.

How this was worked out

We averaged 9 years of National Park Service recreation visitor counts (2015 to 2025, leaving out 2020 and 2021). Each month is shown as its share of that year's total, then averaged. The counts are monthly, so this cannot tell you about holiday weekends or a specific week. It is history, not a forecast. Full details are on the methodology page.
