A total of 960 vehicle reservations—120 per night—will be issued through the lottery process. You can apply for a limited viewing opportunity by entering a lottery for a vehicle pass through Recreation.gov.

Each year, typically in the spring, the fireflies put on a synchronous light display in order to find a mate. They are only species in America whose individuals can synchronize their flashing light patterns. Have this experience on your bucket list?
