Congaree National Park is one of the only places in the US where this particular type of fireflies gather for mating season. It is truly a magnificent sight. Due to the popularity of the event, the park has started a lottery system for entrance passes. If you are interested in seeing this amazing phenomenon in person, you can register to be included in the lottery drawing.
