Grandfather Mountain puts on one of the most remarkable natural events in the Southern Appalachians, and getting in requires a lottery. 

Each summer, synchronous fireflies and blue ghost fireflies light up the northern hardwood forests of Linville during peak mating season. On a dark night in the gorge, the display is mesmerizing. 

The lottery opens May 22 and runs through May 28. Entries are $5 per person. Winners may purchase up to six event tickets at $40–50 each. No waiting list. Winners are notified May 29 and June 3. 

The events run mid-June through mid-July, 7 to 11 pm, on three evenings. Exact dates are announced May 21. Each night starts with a naturalist-led program, then moves to the viewing area after dark. The experience is accessible for wheelchair users and people with limited mobility. No flash photography, no pets, no alcohol. 

Grandfather Mountain has confirmed ten firefly and illuminating insect species on the mountain. Learn more.
