Just outside of the city center, Bogatell is a quieter, clean beach with some excellent chiringuitos (beachside restaurants) lining its shores. If you're looking for something slightly off the beaten path, yet want to remain within walking/biking distance of the city center, this is a great option. The water is often cleaner at Bogatell and if you're not into the naked beach scene then you're in the clear, as Marbella is still far enough away that you don' have to endure the 'eye soars'. This is a day trip or a half day excursion, easy to get to on the yellow metro line (stop Bogatell) or walk there from the city center (about 20 minutes from Frank Gherry's 'Fish').
