About this site
Blue Grotto is a freshwater spring dive site near Williston in north-central Florida, a popular training and certification site inland from the Gulf coast. It centers on a spring-fed basin with cave passages extending underground, reaching a maximum depth of about 30.5 metres, and is rated a beginner dive on the bottom type of cave. Visibility is consistently great thanks to the constant spring flow, and the water stays cool year-round like other Florida artesian springs. There is an air bell within the cavern zone that divers can surface into. The open basin suits divers of varied experience, while venturing further into the connected cave passages requires specific training.
