My son and I use "dry" snorkels sold by Body Glove. These have a valve which prevents water from entering your mouth. When the snorkel top gets in water, the valve closes and no water gets in the snorkel. I like it a lot. You can find them all over the place on the internet, and probably locally. I bought ours from Herrington Catalog, although I probably could find them cheaper elsewhere. I got sets with snorkels and masks (great masks too). They also have nice flippers, although I don't use flippers.
