There are at least 19 different species of fireflies that live within the Great Smoky Mountains National Park and Synchronous Fireflies are one of them. These are one of the rare species in the world known to synchronize their flashing patterns. Important Dates for 2017: Tuesday, April 25: Dates of event and shuttle operating period will be announced Friday, April 28 at 12:00 PM: Lottery for Vehicle Passes opens Monday, May 1 at 8:00 PM: Lottery for Vehicle Passes closed Wednesday, May 10: All lottery applicants will be notified that their application was successful (and they are awarded a vehicle pass) or unsuccessful (and they were not awarded a vehicle pass) Enter Lottery Why Do the Fireflies Synchronize? No one really knows why the fireflies flash together. One theory is that males are competing and they all want to be the first to flash. Or, another theory is that if the males all flash at once they will have a better chance of being noticed, so that the females can make comparisons between them. Experiencing This Natural Phenomenon During this peak firefly display period, you will have a chance to see this amazing display of natural beauty. Great Smoky Mountains National Park organizes a shuttle service that will take you from the Sugarlands Visitor Center to the Elkmont Viewing area. This is where a huge population of synchronous fireflies can be found. The first shuttle leaves the main parking lot at around 7pm. The shuttles will start to return from Elkmont later in the evening when they are full, which will likely be around 9:30pm and they will continue to run until everyone has returned. The viewing area at Elkmont consists of small paved areas and walking trails and the park rangers will be in the area in order to provide information. Winning Tickets Via the Lottery System In order to ride the shuttle and view the fireflies, you must acquire a pass. The number of parking spaces and the capacity of the shuttle is limited. Due to the limited number of spaces, the parking passes will be distributed via a lottery. It is free of charge to enter the lottery and it will open on Friday, April 28th at 12:00 PM. The lottery will close on Monday, May 1 and the winners will be chosen, with the results to be announced on Wednesday, May 10th. The winners will be charged $1.50 and they will be awarded a parking pass. If you win a parking pass, there will be no rain checks, transfers or refunds. In order to use the parking pass the lottery winner must be within the vehicle and must present their photo identification before the vehicle will be admitted to the parking area. Only one application can be completed per household. This is a fair way of giving everyone a chance to obtain a pass for this very high demand event.
