Cinque Terre is easily the most beautiful place I've ever been to. Literally meaning "5 lands", visitors hike along the cliffs, bouncing from town to town, soaking in the breathtaking views along the way. This is one area of Italy that is not known for the food, but has its hidden gems if you take the time to get lost before continuing on. This is especially the right region to enjoy some of the freshest seafood around, usually caught just hours before hitting your plate.
Each village has it's own personality and is worth spending some time in. It's an easy day trip, especially if you decide to take the trains to and from instead of hiking the entire journey. Just be sure to check train times, as they only come about once an hour, so you'll want to time it right.
