Corniglia is the least kid-friendly of the Cinque Terre. It's difficult to access. It offers few services. It doesn't have direct access to the sea. Having said that, there are six reasons to consider a visit. 1) Corniglia is the most sophisticated of the Cinque Terre. 2) It's the only hamlet to sit above the sea. 3) It retains more of its original structure than the other four. 4) It boasts an exceptional panorama. 5) Corniglia is delightfully quiet at the end of the day. 6) It has the best beach in the area.
