Spring at the Smokies is wildflower season — over 1,500 species bloom from late March through May, earning the park the nickname "Wildflower National Park." Synchronous fireflies (mid-late May to early June) draw a lottery permit window for the Elkmont area. The park is FREE to enter. Parking tags ($5/day or $40/year) required starting 2024. Cades Cove and Elkmont are the prize campgrounds. Both book months ahead through Recreation.gov.

Quick answers
Frequently asked
Is there an entrance fee for the Great Smoky Mountains?
No entrance fee — the park is free. However, parking tags are required ($5/day or $40/year) since 2024.
Do I need a reservation for Smokies campgrounds?
Yes — all major campgrounds (Cades Cove, Elkmont, Smokemont, Cosby) require reservations through Recreation.gov. Book months ahead.
When are wildflowers at peak in the Smokies?
Mid-April through early May. The annual Spring Wildflower Pilgrimage (last full weekend in April) brings guided walks.
How do I see the synchronous fireflies?
Lottery through Recreation.gov in late April. Limited dates in late May/early June. Shuttle from Sugarlands Visitor Center.
What the NPS site won't tell you
The NPS rarely promotes this, but: Greenbrier Cove (east entrance, no fee station) has Porter's Creek Trail with one of the densest wildflower displays in the park — and a fraction of the crowd at Schoolhouse Gap or Cades Cove. Park at the Greenbrier picnic area, walk 1.5 miles up the old roadbed.
