Dive to the Wreck of the Titanic
Starting at Newfoundland, if you head roughly 400 miles (600 kilometers) south, you'll find yourself in the middle of nowhere, floating on the Atlantic Ocean. The surface, however, is not what brought you to this point -- you're here to see what lies well beneath the waves and wind above. About 2.5 miles (4 kilometers) below you is the wreck of one of the most famous ships ever to have sailed the seas, the RMS Titanic. From the Russian research ship Akademik Keldyshe, you'll board one of two submersibles capable of withstanding the pressure of diving deep into the ocean. The MIR I and II will ensure you a safe and comfortable ride to the bottom of the ocean, where you'll be one of only a handful of non-scientists to view the wreck of the Titanic [source: Adventures.com]. Just remember to keep your hands and feet inside the vessel!
