Puerto Banus is an easy drive along the coast road (N340). There is ample parking in Puerto Banus although you will have to pay in most carparks. The cinema usually has an English film showing (VOSE) each week and if you get your ticket stamped, you get three free hours parking in the underground carpark beneath the central plaza. You can also park at the department store, El Corte Ingles.
The streets immediately surrounding the marina are full of restaurants and shops and you can have a very pleasant lunch or dinner whilst watching the world go by.
There is also a street market the other side of the coast road, up the hill on Saturdays from about 10 – 2 and this is a popular place to visit.
