The Cinque Terre: Worth it or not?

My husband and I are going to Naples for 10 days in April.

We love to hike and explore. Was wondering if this is a must for people who like to hike & explore towns at their own pace? Is it a one day excursion?

Edit: Some people seem to misunderstand me. I know it’s no where near Naples, What I meant be one day excursion was : can you hike Cinque Terre in one day?
