I’M NOT SURE WHAT THE ADVANTAGE is of having an indoor pool with depths of over 100 feet, but I suppose there is a first time for everything. For people looking to practice their scuba skills without dealing with nasty sea water, or who just get some bragging rights, the Y40 hyrdro facility offers a unique aquatic experience using finely filtered spa water. In the Montegrotto Terme area of Italy, it’s a quick trip from Venice. You can learn more about the facility by checking out their website.
