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 14-21, 2025, entry to the park will be limited to 145 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 4:30 PM. Day-use visitors must exit the park by this time. Access to the firefly viewing area will open to ticket holders at 7:00 PM.
Please visit the park’s Fireflies webpage for additional information about this event.
