This full day tour lifts the lid on Sardinia's secret islands. Hop on a catamaran and you'll spend the day gliding along La Maddalena archipelago, a national park of barely trodden on beaches, turquoise waters and some rose-coloured surprises. There's a chance you'll stop at Spargi, Budelli, Santa Maria, Razzoli or Caprera along the way, where you can dive in for a swim. You'll also have lunch onboard.
