Devil's Den Prehistoric Spring and Campground
Williston
Devil's Den is an underground prehistoric spring inside a dry cave in Williston, Florida, renowned for its crystal-clear 72-degree blue waters and dramatic natural skylight. Visitors descend a steep staircase into the cavern specifically for snorkeling and scuba diving, with casual swimming restricted and mandatory gear required. The unique sinkhole is frequently compared to Mexico's cenotes and requires advance reservations for timed sessions.
Commenters consistently praise the spring's ethereal, magical beauty, though many frequently note that the subterranean water feels freezing cold. Logistical feedback centers around the necessity of booking online reservations to handle crowds and occasional trepidation regarding Florida wildlife like alligators. Despite some concerns over admission costs and crowded spaces, overall sentiment is enthusiastic, with many eager to visit or return.
