How Crowded Is Congaree National Park in September?

September runs about 0.8× Congaree National Park's average month, which makes it a quiet month here — roughly 6% of the park's yearly visitors come in September.

In a typical September the park sees about 12,000 recreation visits, based on National Park Service monthly counts from 1985 to 2025.

That makes September the 10th-busiest of the park's twelve months, sitting between the May peak (1.5×) and the January low (0.6×).

On our Best Time to Visit score September rates 77/100 ("Excellent"), versus the top-rated January at 80/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 22% 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 12.2 hours of daylight in September to explore — between the 9.8-hour midwinter low and the 14.2-hour summer high.

Park-wide, 2025 drew 287,833 recreation visits, up 18.9% from 242,049 in 2024.

Across the past decade overall visitation has risen about 72.3%, so a September visit is likely to feel busier than it did a few years ago.
