Smoky Mountains Fireflies

The Smoky Mountains are known for their stunning natural beauty, from the rolling hills to the cascading waterfalls. But one of the most enchanting sights to be found in this wilderness is the Elkmount Fireflies.

Every year, from late May to mid-June, the synchronous fireflies of Elkmount put on a dazzling display. These fireflies are a rare species known as Photinus carolinus and they are the only fireflies in North America that can synchronize their flashing patterns.

As the sun begins to set, thousands of male fireflies begin to flash in unison, creating a stunning display of light that dances across the forest floor. The females, perched in the trees above, respond with a single flash, signaling their interest to potential mates. The display lasts for only a few short weeks, specific dates can vary depending on the temperature and soil moisture levels.

In fact, the Elkmount Fireflies have become so popular that the National Park Service has implemented a lottery system for viewing the fireflies. To see the fireflies, visitors must enter a lottery system for a parking pass to the Sugarlands Visitor Center. Only 1,800 passes are available per night and visitors are encouraged to enter the lottery as early as possible. Once at the viewing site, visitors are led on a guided walk through the forest, where they can witness the fireflies' spectacular display.

FUN FACT Elkmount Fireflies aren't just a beautiful sight to behold. They also play an important role in the ecosystem. Fireflies feed on snails, slugs and other small invertebrates, helping to keep populations in check. As adults, they are an important food source for bats and other nocturnal predators. Late April 2024, the dates for the official Smoky Mountains National Park synchronous fireflies event in 2024 will be disclosed.

Once the lottery period ends, passes for the Smoky Mountains National Park synchronous fireflies event can be purchased from Recreation.gov. Lottery applicants will be notified on Mid-May 2024 if they have been awarded a vehicle pass. If selected, a $25.00 fee (per vehicle) for the pass. In addition, a $2 fee (cash only) will be required per person when boarding the round-trip shuttle to the viewing area.
