4. Barcelona: Tres Estrellas
Just 7.5 miles from the city center by bus, 3 Estrellas is a beachfront campground that offers tent or cabin camping. You can take one of several buses directly to Barcelona’s Plaza Catalunya, though there are plenty of on-site activities to keep you busy, including the usual suspects–pools, tennis courts– and the “only in Barcelona” options, such as paella demonstrations and flamenco shows.
