Skin diving using a snorkel tube (also called snorkeling) is an outdoor activity that can be enjoyed by water enthusiasts of almost any age. Unlike scuba diving, which requires hours of specialized training, snorkeling can be done by anyone who knows how to swim. It's a great way to exercise while checking out the neighborhood just below the water's surface.
