A must-stop if you're in the Limestone Coast and if you are brave and experienced, this one is a great swim spot. Yes, the water is freezing but it actually is a very popular spot during summer heh. Little Blue Lake is a water-filled sinkhole with a floating pontoon and stairs for access. Do note that there are no lifeguards are not on duty, so swimming is at your own risk, but it’s one of the Limestone Coast’s most unique geological features!
