How Crowded Is Longfellow House Washington's Headquarters National Historic Site in October?

October runs about 1.4× Longfellow House Washington's Headquarters National Historic Site's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in October.

In a typical October the park sees roughly 6,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes October the 5th-busiest of the park's twelve months, sitting between the June peak (1.6×) and the January low (0.3×).

On our Best Time to Visit score October rates 23/100 ("Poor"), versus the top-rated February at 79/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 40% of annual visitors, choosing October instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 10.8 hours of daylight in October to explore — between the 8.9-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2025 drew 54,912 recreation visits, up 6.6% from 51,496 in 2024.

Across the past decade overall visitation has risen about 9.5%, so a October visit is likely to feel busier than it did a few years ago.
