How Crowded Is Golden Spike National Historical Park in September?

September runs about 1.2× Golden Spike National Historical Park's average month, which makes it an average month here — roughly 10% of the park's yearly visitors come in September.

In a typical September the park sees roughly 5,900 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 5th-busiest of the park's twelve months, sitting between the May peak (2.5×) and the January low (0.2×).

On our Best Time to Visit score September rates 68/100 ("Good"), versus the top-rated August at 72/100 — best overall balance of crowds, weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 76°F and an overnight low around 46°F, with about 1" of precipitation.

That average of about 61°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 39% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.3 hours of daylight in September to explore — between the 9-hour midwinter low and the 15-hour summer high.

Park-wide, 2025 drew 53,696 recreation visits, down 2.9% from 55,285 in 2024.

Across the past decade overall visitation has eased about 24.4%, so September may feel a touch quieter than it once did.
