How Crowded Is Great Smoky Mountains National Park in October?

October runs about 1.5× Great Smoky Mountains National Park'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 1.5 million recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes October the 2nd-busiest of the park's twelve months, sitting between the July peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score October rates 24/100 ("Poor"), versus the top-rated August at 53/100 — best overall balance of crowds, weather and daylight.

Typical October weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 59°F and an overnight low around 41°F, with about 5.4" of precipitation.

That average of about 50°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 35% 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 11.1 hours of daylight in October to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2025 drew 11,527,939 recreation visits, down 5.4% from 12,191,834 in 2024.

Across the past decade overall visitation has risen about 9.2%, so a October visit is likely to feel busier than it did a few years ago.
