The Famous Elkmont Fireflies Event

The Famous Elkmont Fireflies Event


Once a year, nighttime magic sparkles around the Tennessee ghost town of Elkmont. Rare fireflies flash their lights in synchronized patterns as if they’re dancing to a beat. This phenomenon happens at only a few places on Earth–and the Smoky Mountains is one of them! Here’s how to witness it for yourself.

What’s so special about these fireflies?

There are more than 2,000 species of fireflies worldwide, but only three of them are synchronous. One of those three species calls Great Smoky Mountains National Park home. To make the event even rarer, this aerial mating dance takes place for only a few weeks in late May or early June, and only in a tiny area around Elkmont. Miss it, and you’ll have to wait a year to try again.

How can I see the fireflies?

Keep a close eye on the website linked here. It’s where you’ll find the National Park Service’s annual firefly viewing lottery.

The lottery protects these delicate insects by limiting access. It distributes parking passes for an eight-day viewing period when only vehicles with passes can enter this part of the national park at night. If you’re a lucky lottery winner, you’ll park and then rangers will direct you to the viewing area.

When is this year’s firefly event?

The viewing period, and the lottery opening date, aren’t set yet for this year. Typically, the lottery opens in late April and the viewing period is in late May or early June.

Is there a cost?

Everyone who enters the lottery pays a $1 application fee. If you win a coveted parking pass, you’ll pay another $29. The money pays for supplies and staff to manage this special event.

Can I see these fireflies without a special pass?

The only way to be sure of seeing this natural treasure is to nab a lottery pass. You might spot synchronous flashing on dates before or after the eight-day event. The national park is open 24/7, but some roads and trails close at night. Check whether the Elkmont area is open after dark. If you’re in the area at night, always stay on the trail and don’t use flashlights. White light disturbs the fireflies.
