Thats where I did some of my check out dives a few weeks ago, it was a neat place, especially for a beginer. We were there on a week day and were the only people there, which made it nice. I was told on some weekends you have to wait to get in and out of the water because there are so many people in the spring. This is because there is a set on steps that leads down into it. Almost right across the street is blue grotto, We didn't dive there but I just wanted to mentioned it for anyone planning a trip to the den. You talk about a money pit in your back yard, wish I could find a sink hole in mine that I can charge 30 bucks to get into lol......
