A mix of Arabic baths and amazing massage, the Banos Arabes (Hammam) at Barcelona's Aire, Spa are soothing and incredibly relaxing. This is an excellent couples activity or perfect for a rainy day if you want to feel warm. The Arabic baths are made up of several pools, some hot, some cold and then the extremes being piping hot and ice cold. You're given an hour in the baths and then if you book the massage as well, there's a small room to the side where one you can enjoy a 20 minute or hour long massage. The spa is right near the Picasso Museum and other boutique shops in the Born and delicious restaurants.
