The time is drawing near for synchronous fireflies to once more light up the night in the Smokies, and the Great Smoky Mountains National Park has announced this year’s dates for up-close firefly viewing at the park’s Elkmont Campground. 

The park has a limited number of passes to see the fireflies from Tuesday, June 2, through Tuesday, June 9. The passes, which cost $1.50 each, can be reserved starting at 10 a.m. Thursday, April 30, at www.recreation.gov. Typically, they sell out within minutes of going on sale, though the park holds back 85 passes for each day to go on sale at 10 a.m. the day before the event. 

During each evening, shuttles ferry viewers to and from the campground for an additional $1 per person. The prices are designed to regulate the number of people flooding the site at any one time rather than as a way for the park to make money. 

Synchronous fireflies are a particular species of firefly that lives only in certain habitats at certain elevations. For a short window each year, they give a showy mating ritual in which all the males in the forest blink simultaneously, making the forest appear to be lit by blinking Christmas lights. The annual event at Elkmont attracts viewers from across the region.
