Devils Den is a great cavern dive near central Florida. Be careful on the steps as you descend into the mouth of Devils Den. And watch your head as you go under the rocks. You’ll see some large catfish that are apparently trapped in the cavern (or maybe they know a secret way out). While underwater, spend time looking up at the light coming through the cavern and into the water. Bring a couple lights, it’s not really a cave...but there are some spots that get dark since it can become pretty enclosed. If you don’t like tight spaces, try to avoid going through some of the small openings. I never had to take off my gear to push through, but I didn’t have to wiggle my way through some spots.
Don’t go beyond the bars or signs underwater, they’re there for a reason. Checkout the neat bones and other stuff lying on the floor in some spots...this place really does seem pre-historic.
There are training platforms to use and a pool on site as well. The cabins on site are also very nice and cozy (with kitchens and bathrooms).
