Blue Grotto Is a Must-See for Beginner and Expert Divers Alike

    By Bob Giguere

    Near the small town of Williston, fern-draped Blue Grotto's large clear-water cavern draws divers from across the country. Open to all skill levels, the maximum depth you can reach is 100 feet. A highlight to this site is the compressed air-supplied bell at 30 feet. You can enter and take the regulator out of your mouth mid-dive and talk to your buddy.
