Swimmers wanting to fetch something off the bottom of this pool will certainly need more than a lungful of air - seeing as it's a staggering 113 feet deep.
Located in Brussels in Belgium, Nemo 33, the world's deepest swimming pool, contains a whopping 660,500 gallons of non-chlorinated, highly filtered spring water that is kept at a temperature of (86F).

Meanwhile, for those that don’t want to take a dip, there are fourteen underwater windows that allow outside visitors to view all the underwater action.
