GATLINBURG, Tenn. — The Great Smoky Mountains National Park has announced the dates for one of the most spectacular natural light shows in the country.

The viewing for the synchronous fireflies event at Elkmont will be May 30 through June 6. Everyone who wishes to see the fireflies during this time must have a parking pass distributed through a lottery system or be booked at a campsite at Elkmont.

Elkmont is one of the few places in the world where you can see the Photinus carolinus, the special kind of firefly that flashes in unison. The event has become so popular over the years that the park has had to take steps to limit the number of people that could view the fireflies each night.

During that period, which is estimated by park scientists to be the peak time for the fireflies, a parking pass is required for evening access to the Sugarlands Visitor Center parking area and the firefly shuttle to the Elkmont viewing area, according to the National Park Services.

People hoping to attend the annual spectacle are asked to submit their name to the lottery for parking passes on the Recreation.gov Firefly Event pageLottery applications will be accepted from Friday, April 26 at 8:00 a.m. until Monday, April 29 at 8:00 p.m. Results of the lottery will be available on Friday, May 10.

The parking pass permits visitors to park at Sugarlands Visitor Center and allows occupants to access the shuttle service to Elkmont. The $24.00 reservation fee covers the cost of awarding the passes, event supplies, one red-light flashlight per pass, and nightly personnel costs for managing the viewing opportunity at Sugarlands Visitor Center and Elkmont.
