Hartley's Helmet Diving is Bermuda's premier undersea walk. Greg Hartley, who's family started helmet diving over 75 years ago,
had his first dive at age 3. Their reef is just under 2 miles out, half way to the pristine waters of Bermuda's barrier reef, yet only 10ft
deep. Great for all ages 5-85, meek or macho, certified or non-swimmers.
