Be sure to check the dates of this years Synchronous Fireflies In The Smoky Mountains National Park event. This literally shuts down everything in Pigeon Forge and Gatlingburg for a week... It is in the May/June time frame - can't remember the actual dates... There will be peoples everywhere...
This is the only place in the USA where this happens so it is a "Big Deal" event...
The special species fireflies that do this are at the ELKMONT Campground inside the Smoky Mtn Natl Park... We got caught up in this event one year... Certainly is a sight to see for sure...
