Wakulla Springs is the deepest freswater spring in Florida and considered one of the largest 1st magnitude springs. It is owned by the state and operated as a park. No scuba diving is allowed and snorkling is confined to a roped off area that does not extend over the basin. Depths plunge straight down to a large cavern entrance at 125 feet. Depths continue to 185 feet + through an extensive cave system that is still being mapped and explored by dive projects. Sadly, you will have to be satisfied with a bottomless boat ride to see the large spring bottom. This is the benchmark of all Florida springs in size, volume, and depth.
From Tallahassee, take S-61 14 miles to Wakulla Spring Road. Look for large sign.
