How Crowded Is Glacier Bay National Park & Preserve in October?

October runs about 0.5× Glacier Bay National Park & Preserve's average month, which makes it a quiet month here — roughly 4% of the park's yearly visitors come in October.

In a typical October the park sees about 23,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes October the 6th-busiest of the park's twelve months, sitting between the July peak (2.6×) and the February low (0×).

On our Best Time to Visit score October rates 38/100 ("Poor"), versus the top-rated April at 58/100 — 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 45°F and an overnight low around 37°F, with about 10.2" of precipitation.

That average of about 41°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 62% 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 9.8 hours of daylight in October to explore — between the 5.9-hour midwinter low and the 18-hour summer high.

Park-wide, 2025 drew 740,044 recreation visits, about flat from 736,282 in 2024.

Across the past decade overall visitation has risen about 20.2%, so a October visit is likely to feel busier than it did a few years ago.
