Â
Great Smoky Mountains National Park will host the annual synchronous firefly viewing opportunity at Elkmont beginning Tuesday, June 1 through Tuesday, June 8. The public may apply for the limited viewing opportunity by entering a lottery for a vehicle pass through www.recreation.gov. The lottery opens for vehicle pass applications on Friday, April 30 at 10:00 a.m. through Monday, May 3 at 11:59 p.m.
Every year in late May to early June, thousands of visitors gather near the popular Elkmont Campground to observe the naturally occurring phenomenon of
Photinus carolinus, a firefly species that flashes synchronously. Since 2006, access to the Elkmont area has been limited during the eight days of predicted peak activity in order to reduce traffic congestion and provide a safe viewing experience for visitors that minimizes disturbance to these unique fireflies during the peak mating period.
