Devil's Den Prehistoric Spring
A prehistoric spring pool hidden in an underground limestone cave. Sunlight falls through a small hole in the ceiling onto the blue water, and snorkeling or scuba diving can be booked.
Devil's Den lies on the outskirts of Williston. It is a dry limestone cave with a clear spring at the bottom, and on winter mornings vapor rises from the cave mouth like smoke, which gave it its name. Fossils of Pleistocene animals have been found inside. Visitors go down steps into the cave to snorkel or dive beneath the stalactites, and the scene is most beautiful around noon, when sunlight streams in through the roof. Time slots must be booked in advance on the official website. Tickets start at about $20 on weekdays and cost more on weekends. Masks and fins are available for rent. Simple swimming is not allowed. It is about 60 km (around 1 hour's drive) from Crystal River.
