A city beach is called Platja Barceloneta. There is a bus from Plaza Catalunya that takes you there or you can walk for around an hour. Beach looked kind of hippy and there was lots of action going on.
We stayed at the Hotel Arts in Puerto Olimpico and decided to just wander about... we started at the boardwalk, watched beachgoers having fun tanning/ playing on the beach, passed by a beautiful parc where everyone was taking a siesta, and ended up in La Barceloneta. We found a close-nit community and saw how people really lived in BCN. The alleys were small and filled with a lot of appartment complexes. Everyone was friendly and you get the feeling of being in a real neighborhood with kids playing and neighbors talking with each other... like you were at home. The prices at the markets and little mom and pop restaurants were reasonable since it wasn't a tourist's must see activity.
Beaches in Barcelona city are dirty and crowded. I very rarely go there unless its for a beach party. If you want a nice beach to visit there are plenty within an hours train journey going either up or down the coast. You can get trains up the coast from Plaza Catalunya Renfe trains heading towards Mataro or Blanes. They run up the coast so look out the window and choose a beach you like the look of (St Pol is the nicest, but an hour away).
You can also go from Passeo de Gracia towards Vilanova to any of the beaches south of Barcelona. These include Castelldefels and Sitges. These beaches unlike the north of Barcelona are made naturally so don't get deep quickly, unlike the north ones. (Personally I prefer the north ones, but the south ones are good for surfing and families)
Not exactly obscure, but I think many visitors to the city may not venture here. Not the Costas, but I live inland so love a stroll along the beach with the breakers crashing in. Just the thing for an hours break from the buzz of the city. And in summer, a couple of hours having a paddle and catching some rays.
On the day I was there, there were even some hopeful surfers out.
The beaches quarter in Barcelona.. since 1992 has become in the most popular area above all in Summer. Here Barcelona recovered their beaches where there are industries for a long time ago.We have 4, but i suggest 2 beaches .. Bogatell and Nova Icaria.
La Rambla de Poblenou arriving by yellow metro line in Poblenou station or Llacuna you can find a charm avenue with a lot of shops, that arrives from Diagonal Avenue to the beaches
Diagonal Center a new comercial area at the end of diagonal besides the sea ..shops shops and more shops!!
Glories Centre Comercial other comercial area in glories square (subway line 1 glories).. too much people above all on weekend. be careful !! lol
Try 2 walk a little in Cadaques, it still has the old charm of those white houses,long streets, balconies with red flowers...
If u want 2 visit Port Lligat, the place where lived Salvador&Gala Dali, u have 2 pass thtough Cadaques- a beautifull village where a lot of wellknown artists came for holiday.
There was nothing better than lying on the beach with a nice cigar in Barcelona, I suggest it for EVERYONE!
