Congaree National Park Firefly Viewing Lottery

Congaree National Park is home to a number of different species of fireflies, but it is the synchronized fireflies that lure thousands of people to the park each spring. These fireflies are one of only a few species around the world that synchronize their flash patterns in a majestic ritual that heralds the coming of summer. This late springtime display is part of their annual mating ritual that takes place for approximately two weeks, typically beginning around mid-May, along the edge of the Congaree floodplain.

During the evenings of May 20, 21, 22 & 27, 28, 29, entry to the park will be limited to only 120 vehicles displaying a valid event pass. Event passes will be distributed via lottery in order to provide an equitable opportunity for all interested visitors in this limited, yet high-demand event. During the event, the park entrance gates will close to entry at 4:00 PM.

Day-use visitors will exit the park by this time. Access to the firefly viewing area will open to ticket holders at 6:30 PM. During non-event days the frontcountry areas of the park (including the entrance road and visitor center) will be closed to the public after 4:00 PM.
