Devil's Den when I was there had terrible vis, it was early in the morning and only an instructor and student had been in before us. Either they destroyed the vis or it is not crystal clear like they say.
Some of the swim throughs turned into restrictions only one person could fit through which is actually the definition of a cave, not cavern. Once in the swim throughs, sometimes one could not see light, and some of them are actually caves, not barred off.
Blue Grotto is also a low flow cavern with a huge area up front, fairly shallow, and then a back area that goes deep. It is very silty on the walls and floor. Vis there is amazing.
I also went to Ginnie, which has an excellent camp facility if you are into that, beautiful area of cypress trees right on the river, stunning. The cavern dives there are very cool on that level also. The flow is much, much higher, so silt is not really an issue as much.
On any of these make sure your lights work well, good batteries, and have backups. One could get in trouble in any of these. They should all have a cavern definition light source easily seen, but that was a good bit lacking in my opinion.
I also looking for an easy dive in that area beyond the three I mentioned. Something on the cheap side would be cool, but any are welcome. I have read a bit about Troy, any one been there?
