James Cameron made international news in March 2012 when his one-man submersible journeyed to the Challenger Deep, the deepest point of the ocean, some 6.8 miles down. The Challenger Deep is located in the Marianas Trench, just 250 miles southwest of Guam. Guam is home to a handful of dive shops and is a diver’s dream complete with wrecks, vibrant reef systems, and temperate tropical weather.
