How far ahead to book Buttermilk

For July weekends, book about 173 days ahead. Three in four July Friday and Saturday arrivals were booked later than that, and half were booked 108 days or less before arrival. Past timing is guidance, not a guarantee of what is open now.

Months with fewer than 30 reservations of that kind are left blank. Sites where nearly every booking was made the day of arrival (pay on arrival) are left out. Closed seasons, windows not yet released for booking, and currently unavailable nights are separate from this history.

Based on Recreation.gov reservations, FY2015–2025 (4,983 reservations in the years scored). Counts reservations made, not nights actually camped: cancellations aren't in the data, and nights a site was closed count as not booked. FY2020–21 (COVID) are left out of the scores.
