This is a great dive site as long as there are not many people in water. When I went earlier this year, no one was in the water and it was like swimming in a fresh water aquarium. Visibility was 100+ feet. My 10-year old daughter did two of her OW certification dives here and she really enjoyed it. We sat on the big log that is above the opening of the cavern and we could feel the force the water coming out of the cavern (not really strong, but definitely noticeable). The bottom of the spring is somewhat silty. I can see how visibility could go downhill fast if there were many people in the water or scuba divers with poor buoyancy control that cannot stay off the bottom. Since the water is about 68-70 degrees year-round, most divers will want a 5 mm wetsuit with hood, gloves and boots, especially when doing multiple dives. I use a 3 mil full wetsuit with a 5mm hooded torso warmer. My daughter uses a 6mm full wetsuit. The are no facilities at this spring. If you are traveling with children or non-divers, you may also want to consider Vortex Spring. Nonetheless, we had a great time diving at this spring.
