Peak time to view the phenomenon this year is June 2 through June 9. The event has become so popular that the Park Service now limits car access to the campground to registered campers, but others may visit the site via shuttles from the Sugarlands Visitor Center.
As the purple shade of night draws across the darkening forest in late May and early June at Elkmont in the Great Smoky Mountains National Park, it brings forth an amazing light display as slowly, then steadily, thousands of fireflies emerge from the lush undergrowth. Looking like tiny, twinkling earthbound stars, the fireflies blink in an age-old mating ritual. These unique fireflies (Photinus carolinus) are one of 19 species in the park and are the only ones that can synchronize their flashing lights, and by mid-evening around 9:45 p.m. visitors find themselves surrounded by a remarkable display uniquely arranged by Mother Nature. Male fireflies soar and flash while females remain stationary and respond with a different flash.
