La Mar Bella or Marbella is a 20-minute walk from the Poublenou stop on the #4 Metro line. It's known as a nudist beach popular with the young LGBTQ crowd. The nudist section is screened by a long hillock of bamboo. Created as part of the urban renewal that came with the 1992 Summer Olympics, La Mar is big on water sports - windsurfing, Hobi Cats, kayaks - with drink kiosks and lounge and umbrella rentals. It even has a "biblio-beach" rental library.
