Great Smoky Mountains Firefly Show Already in Full Swing in the National Park.

Who doesn’t love fireflies? Young and old alike love to see them flash in the night and the best place in the United States to see fireflies is in the Great Smoky Mountains. Even though the official synchronous firefly event in the Great Smoky Mountains national park does not take place unit next week, the lightning bugs are already putting on an exceptional show already that you won’t want to miss!

Just a few minutes before dusk you will start to see some of the synchronous fireflies start to flash. As it gets even darker the number of fireflies increase at which point they appear to synchronize as well.

Best synchronous firefly shows seem to be on an evening after a light rain in the afternoon and when it is not raining right before or at dusk.

The firefly show will be in places tonight such as in Elkmont, Tremont, Metcalf Bottoms and the Cherokee Orchard / Roaring Fork outside of Gatlinburg Tennessee. There are slightly less active fireflies in Cades Cove right now but that should pick up throughout the week.

Before you get any ideas, both the Elkmont and the Cades Cove campgrounds are booked solid.

Wherever you go to enjoy the fireflies in the Smokies, think safety first. Keep out of roadways, beware of areas with step drop offs, and keep kids under control at all times.

Since turning on any light source such as flashlights, or using a cell phone creates enough light to stop the light show and reduce your night vision be extra careful not to trip over roots and rocks that may be hard to see in the dark. Lights also annoy the heck out of others as well.

This is a fairly buggy year and since you will be fairly close to water where there are always more insects, bring along some bug spray.

The safest way to see the fireflies is during the official GSMNP firefly program, but with such a limited number of tickets, many won’t have the opportunity to enjoy it this way and in order to see our special Smokies firefly, may need to be more adventurous.

Synchronous fireflies and their admirers are about to invade the Great Smoky Mountains national park

In a few days just as they have done for years, millions of the Smokies beloved lightning bugs will start to shine with their amazing bioluminescence that will synchronize with one another. While this is happening about a 1,000 people a night will crowd the Little River Trail in the Elkmont section of the GSMNP which was a former rail road bed for the Little River logging company to watch and be amazed by natures light show.

Actually there are 14 species of fireflies that have been identified in the Great Smoky Mountains national park, but only one the Photinus Carolinus, performs its magical light show in a synchronized manner that is always a crowd pleaser.

This little former glowworm emerges at around 55 degrees Fahrenheit and likes to keep by slow moving water while it uses its greenish glow to attract mates. This phenomenon actually takes place all throughout the southern Appalachian Mountains, but the best place to observe it is in the Great Smoky Mountains national park, and Elkmont is one of the most convenient and safest places to observe these fireflies flash at what could be their mates.

While you can observe synchronized fireflies in virtually every section of the GSM national park, in order to accommodate so many visitors who come for the light show, the national park service has decided to close Elkmont entrance road at firefly peak season to anyone other than registered campers at 5 pm. No parking is permitted along Little River Road at this time so that cars will not hit pedestrians in the dark.

What the Great Smoky Mountains national park does do for visitors with the help of the City of Gatlinburg, which provides trolleys, is run a shuttle for $1 round trip from the Sugarlands visitor center starting 7 pm to the Elkmont trailhead.

As soon as the parking lot at the Sugarlands Visitor Center fills up or it is 9:00 pm, no more people transportation to Elkmont ends. Most every run may sell out, so come after 6:00 pm to be sure you will get a seat on a trolley to see firefly show!

If you are bringing a flashlight, you need to bring red cellophane or a red lens cover so as not to disturb the fireflies flashing or other visitor's night vision. You can only bring what fits on your lap and no coolers alcoholic beverages, or pets can go on the trolley.

The park advises the last trolley will return to the Sugarlands at 11 pm, however historically the last trolley is much later but be there before then so you will not be left in the dark at Elkmont!

Peak firefly season when the trolleys will be running and Elkmont road is closed this year will be from June 5th to the 13th.

Great Smoky Mountains National park hosts synchronous firefly show for the next 2 weeks.

Starting tonight visitors to the Great Smoky Mountains national park are in for a special treat while the synchronous firefly beetles found in the Elkmont section of the park will flash their lights all in unison.
Fireflies also commonly known as lightning bugs can be found elsewhere and the Great Smoky Mountains national park has 14 species that have been identified within the park but only the species called Photinus Carolinus attract their mates with flashing lights within their bodies in a synchronous pattern.
The light given off buy the fireflies is actually a chemical reaction between chemicals within the fireflies, oxygen and an enzyme produced by the beetle. This light also known as bioluminescence is light green for most fireflies and one is bluish.
The exact timing of when it is best to observe the synchronous firefly beetles depends on weather and other condition and although the lightning bugs can take up to 2 years to mature, the light show taking place in their mating season only last around 21 days. The best guess is that this year next week will be the best week to observe the phenomena.
When watching the light show you will notice that to fireflies don't always flash in unison. You may observe different light patterns that they will make such as all the lightning bugs flashing randomly, then in waves across the hillside and then they will all flash together and all stop leaving some momentary periods of darkness.
Visitors to the fireflies should have bug spray and if you are bringing a flashlight it should have a red setting or you bring along red or blue cellophane to cover the light so as not to interfere with the fireflies and other observers night vision. Lights should be pointed to the ground and turned out in the observation areas.
Since this has become an extremely popular attraction with visitors to the park and Elkmont has limited parking, a shuttle service is in place from June 7th to the June 14th at the Sugarlands Visitor Center near Gatlinburg. Riders who take the shuttle to Elkmont pay only $1 for a round trip ticket.
Due to crowding in Elkmont and the potential for pedestrians being hit while walking back to their cars in the dark along Little River Road, no parking is allowed in Elkmont or along the road sides so if you wish to see the fireflies, you must take the shuttle from The Sugarlands Visitor Center.
