Mar Bella beach is approximately 500 m long. It is located to the East of the Barcelona coastline and is one of the beaches that came into existence after the urban redevelopment of the coastal area as part of the 1992 Barcelona Olympic Games preparations.
The users are mainly young people and a significant portion are residents in the Sant Martí district, under whose constituency this beach falls. The Mar Bella beach's public is loyal and numerous, returning every week to this beach which is easily accessible by bicycle, since it is bordered by the cycle track.
The Mar Bella beach has a designated nudist beach area. Next to the Bac de Roda breakwater there is a children's play area and a volleyball court. It is on this breakwater where the Beach Library is set up in July and August.
Other recreational facilities include a basketball net, a skating area, a ping-pong table located on the upper part of the Seafront Walkway, next to the Mar Bella sports centre.
At the Western end of the beach, there is a nautical base where all activities relating to the sea are performed.
