We leave to you the choice of the hobbies you like more but it is good to remember that a trip on tha sail boat as to do diving will be an memorable experience, if you suffer of seaseckness it certainly will be, all sporting activities are well advertised in the kiosks at the sea (where in the evening yuo can have music, festivals, rapresentations and various partys). Tennis, Calcetto and Basket are common and present services but however we want to insist to rent at least a canoe and live the sea, in yor town to the return courts will be still presents. Then do not forghet that the sea however beautiful can be dangerous have care to partdridges wide style if much shaken, we can sudgest an alternative trip for example in Costa Smeralda, as alternative we sudgest a trip in the center of Sardinia, it will be an delightfull surprise.
