Diving is the best sport in the world, but like all high-adrenaline activities, things can sometimes go sideways. When they do, your level of preparation can make all the difference. 

Most divers probably put “cage diving with great white sharks” high up on their bucket list of must-have dive experiences. But how many of us are truly serious about doing it? Adding it to a list of scuba fantasies is one thing, but actually putting yourself inside a steel cage and coming face to face with the world’s greatest predator is an entirely different matter. For all those who wonder what it would be like to make that epic leap from the safe confines of fantasy into the bone-chilling world of reality, check out field editor Terry Ward’s blog and photo gallery below documenting her first experience cage diving with great whites off Guadalupe Island, Mexico.
