Antibes is 20 minutes from Nice by train. Its old town is amazing — dark, twisty, under-and-over streets and archways. This part is separated from the sea by a frankly intimidating stone wall. From the Port Vauban (home to multi-million dollar yachts and sailboats), all you can see of the city is the Musee Picasso, because its in a castle at the original town’s highest point. It’s very much a seaside resort, summery place.
