2. The Mariana Trench – Pacific Ocean

Some places for travel adventures are very pricey but I can dream. On my ‘wish list’ is a trip to the deepest spot in the Pacific Ocean. It’s a trench 10,9111 km down. Seriously, imagine travelling that distance underwater – awesome! The last manned expedition was in 2012 by James Cameron, the filmmaker. In total, there have only been two other manned descents. Virgin Oceanic and Triton Submarines are arranging future descents. Interested?
