Good Dive Spot Near Austin?

Should have taken the course in San Marcos, great diving, the dives are free and they will fill your tanks when you are done. BTW, its the perfect place to practice cave/cavern diving, too bad you missed out.

So how do you 'practice' cave/cavern diving in the San Marcos??

First, you are diving in what is essentially a confined limestone karst aquifer. The specific gravity of the water and the temp are exactly the same conditions you find underground. Therefore, your exposure protection and weighting are the same. In addition, you at shallow depths so your wet suit is very buoyant. As an added bonus, instead of a hard ceiling in a cave, you have minimum wage student boat drivers with unshielded props running on top of you to make sure you don't get close to the surface and we don't crawl along the bottom because it would hurt the critters. Sounds like perfect place to train, stay off the bottom so you don't hurt the critters, stay off the top so you don't get cut up.
