Not only is this the COOLEST place to go for a dip, but you'll find year-round events at this funky indoor/outdoor pool. Located on barges - the pool, sundeck and cafe offer a great escape from the summer heat (and is enclosed in the winter so you can warm up!); as well as fun DJ and music events. The price of admission is very reasonable (around 5 euros) and you can easily spend the day splashing around, watching the ships go by and chilling out well into the evening. So pack your bathing suit!
