Looking for beach day recommendation in or near Barcelona. My daughter & I will be in Barcelona 5 days in July while waiting to meet up up with her sister finishing a summer abroad program before heading to Budapest. Would like one day of beach & relaxation. I see mixed reviews re: the beaches in Barcelona. Is there one you would recommend or do you think it would it be worth it to head over to Costa Brava for the day? Need shade (umbrella rentals) and would like water sports, not necessarily motorized, enjoy kayaking, snorkeling and minimal crowds (yes I know its summer, just don't want to have to fight for a spot).
Thank you.
