Great Smoky Mountains National Park
Synchronous Firefly Viewing

Date: May 29, 2008
Contact: Sugarlands Visitor Center, (865) 436-1291

June 9, 2008 update — The synchronous fireflies at Elkmont are displaying currently. Synchronicity has been very good on some nights this year.


Elkmont entrance road will be closed nightly from June 7-14.

Great Smoky Mountains National Park officials have announced that the Elkmont entrance road will be closed to motor vehicles and pedestrian use every night starting at 5:00 p.m. until midnight, June 7-14, except to registered campers staying at the Elkmont Campground. The closure is to accommodate transportation service for visitors planning to spend the evening viewing the natural-occurring, synchronous firefly beetles at Elkmont.

The City of Gatlinburg, in partnership with the park, will provide the trolleys for this activity. The trolley service, coinciding with the expected peak flashing period, will be the sole transportation mode for visitor access during this period; no private vehicles will be allowed to enter Elkmont. This year also new restrictions will be in place to prohibit motor vehicles from parking along roadsides, pullouts, or any other areas besides at the Sugarlands Visitor Center parking area for the purposes of viewing fireflies at Elkmont. Only those visitors parking at the visitor center will be allowed to ride the trolleys.

Chief Park Ranger Bill Wright said that "There is a growing concern over the number of people parking in undesignated areas, along roadsides with narrow grassy shoulders that do not have adequate space for getting in and out of vehicles. Walking along the roadsides, along blind curves and, in some instances in traffic, are high risk factors, especially in the dark after coming back from Elkmont. This also means that visitors will not be allowed to park their vehicles along Little River Road and walk to Elkmont. Park Rangers will be at the closed gate at the Little River Road/Elkmont Entrance Road intersection to enforce the closure."

The trolleys will begin picking up visitors from the Sugarlands Visitor Center RV/bus parking area at 6 p.m. The trolleys will continually run until the Sugarlands Visitor Center parking area is full or until 9 p.m., whichever comes first. The last trolley to return visitors from Elkmont to the Sugarlands Visitor Center is scheduled at 11 p.m. The cost will be $1 round trip per person as in previous years.

The annual appearance of the synchronous firefly beetles, which occurs during their mating behavior, has become so popular that park officials began managing the number of visitors to the trailhead several years ago. The Elkmont area has very limited parking spaces that were designed to accommodate day use for several trails. The dates that the mating behavior begins can vary each year due to weather and other natural factors, but generally starts around the second week in June.

"Our main objectives," Ditmanson said, "are to improve the experience by minimizing crowded conditions thereby reducing safety and traffic concerns and curtailing potential resource damage. These changes will also help to preserve a good experience for campers at Elkmont by diminishing the traffic in the campground and disruption of passing vehicles from the noise and headlight glare."

For those riding the trolleys, it is recommended that visitors bring flashlights with red cellophane covers to reduce white light. Visitors can bring lawn chairs, and carry food and water in backpacks which can fit on their laps in the trolleys; there are no services available at the site. Visitors are prohibited from bringing coolers, alcoholic beverages, or their pets.

Flame azalea can be found growing on heath balds in the park.  

Did You Know?
The park’s high elevation heath balds are treeless expanses where dense thickets of shrubs such as mountain laurel, rhododendron, and sand myrtle grow. Known as “laurel slicks” and “hells” by early settlers, heath balds were most likely created by forest fires long ago.
