Well if you are going to come here in Viareggio just tell me, i know lots of good places, both beaches and nice and traditional seafood restaurants ; )
Yes, Tellaro is beautiful, but with young children i prefer to go to sandy beaches, like Marinella and ofcourse Viareggio. I have friends in La Spezia for more then 25 years so i'm often in that area. We went to Osteria Di Redarca, near Tellaro, fantastic restaurant!
