The kids will sleep soundly after frolicking by the water at Spiaggia di Mezzavalle. Search for fish and other marine life, dip a toe in the water or kick a ball around!
You'll have no end of sightseeing choices when spending time in Ancona. Spiaggia di Mezzavalle is a great place to start here, but there are plenty of other worthwhile sights to check out. Mount Conero, Beach of the Two Sisters, and Palaindoor are close to the stretch of coastline and will fill in your day nicely.
