Club Natació Atlètic-Barceloneta

This is a great facility and friendly to visitors.

This facility has indoor and outdoor lap pools. In July, the outdoor pool was too warm for most lap swimmers (~85º F. [29º C.]) but the indoor pool was nice and cool - probably about 80º F. (27ºC.). I shared a lane with one other swimmer. The lines painted on the bottom of the pool did not correspond with the lap lines/walls, which made it tricky to navigate at first... But, overall, it’s a decent spot.

Pricey at 14 USD for a day pass. But there are lounge chairs so you could easily spend a leisurely afternoon there.

A truly excellent lap pool. Or, actually, pair of lap pools -- one inside, one outside. Both are 25m and, on a visit in early November, 2018, the indoor was a lovely 81ºF (27ºC) with one swimmer per lane, and the outdoor was an eminently swimmable 78ºF (26ºC) or so, with no more than split lanes. The view of the Med and Barcelona's best beach is spectacular. Situated in Barceloneta, a cute neighborhood between the harbor and the sea, the facility offers swimming, gym workouts, and tennis, and though the price is fairly steep, it's an all-day in and out ticket. Showers and locker rooms are fine; bring your swim cap and shower shoes. There's a nice shop for reasonably-priced swim gear too. Go for paella at nearby Can Sole afterwards (reservations might be wise after 2).

Nice view outside. Great experience to swim next to the sea and palm trees. Two pools outside; one for play and one for swim training. Narrow lanes.

Great outdoor pool for swimming laps. Went in February and it was very comfortable swimming outside.

This is a lovely pool, perfect temperature. I swam outside on a September Saturday afternoon and it was not busy. I had a lane to myself.

Lovely indoor pool never overly busy, with views to the beach also. Clean, well managed, and worth every Euro. A decent gym also available with restaurant adjoining. The water polo team is 1st class, with one winning the national championship in 2007.
