2019 Synchronous Fireflies Season (Updated May 27, 2019 at 10:00 am)
And that's a wrap on the 2019 Congaree National Park Fireflies Festival. We are so glad to have had so many wonderful visitors come out to the park this year to see this amazing natural light display. Firefly activity continues, but synchronization seems to have come to an end throughout most of the park. We hope to see many of you again, along with many new faces as well, next year when these charismatic little beetles return for another dance in the dark here at the park
Visitor Center Trailhead Closed to Dogs During Festival
Due to the increase of visitors coming out to see the fireflies and crowded conditions around the visitor center and along the Firelies Trail, the Harry Hampton Visitor Center parking area and trailhead will be closed to dogs from 6:00 PM until 10:00 PM. This is for the safety of both your pets and your fellow visitors. Visitors who would like to to come out with their pets and see the synchronous fireflies have the option to see them at the Kingsnake Trailhead, located at the South Cedar Creek Canoe Landing.Synchronized fireflies have been confirmed in good numbers there for visitors to observe and have been putting on quite a show the past few nights.

The Harry Hampton Visitor Center will be open until 10:00pm nightly from Friday, May 10 through Monday, May 27. Please note that the exact date of when the synchronous fireflies will begin is not known. They are normally active during a two to three week period sometime between mid-May and mid-June.During this year’s event there will be a designated Fireflies Trail, which will give access to prime viewing areas. This one-way trail will start at the Picnic Shelter, go under the elevated Boardwalk and will end at the Harry Hampton Visitor Center. Because of the large numbers of participants, the elevated section of the Boardwalk will only be open to those with mobility issues during evening hours.
Because of the large numbers of participants expected for this event, the following are prohibited on the Fireflies Trail:
Using Smartphones as Flashlights
Chairs, hammocks or blankets
Applying insect repellant (please apply prior to arriving at the park)
Participants are asked to observe the following viewing etiquette:
Keep noise levels to a minimum so that everyone can enjoy this special natural occurrence.
Capturing fireflies is not allowed within Congaree National Park.
Stay on the designated trail (walking off trail can adversely impact firefly habitat).
Wear sturdy, close-toed shoes (roots and biting insects may be present)
Only use flashlights when absolutely necessary, pointing them straight down so as to not disturb other participants (Small penlights are recommended).
Other important information about the Fireflies Festival:
Parking is very limited. Carpooling is highly recommended.
Due to the high volume of vehicles, there will be no RV and oversize vehicle parking during festival hours. Drivers should plan to drop off passengers and have a set time to return to the park to pick them up.
Be prepared for the weather. Thunderstorms often occur in the evenings during May.
The best time to view the fireflies is just after dark, usually between 9:00pm and 10:00pm.

With over 2,000 species found world-wide, there are only three species of synchronous flashing fireflies that can be found in North America. Every year, Congaree National Park hosts synchronous fireflies for approximately two weeks between mid-May and mid-June. During this time visitors can experience an awe-inspiring display of synchronous flashing while the fireflies search for a mate.
