The Public pool in Biarritz is a salt-water pool with 2 basins (the one for swimmers is 25 Meters…read morelong) and 1 whirlpool. There are also some lounge-chairs from which you have a great view of the beach. Sauna and a Hamman are also available but I didn't use those.
The entrance fee is dead cheap (2,50€ for a single adult, 10 entrances cost 18€) but the entrance system is needlessly time consuming. After paying they give you a plastic card with your entry code that you then feed to the entry turnstile literally half a meter next to the lady behind the counter, the card is then gone and has no more use - even if you buy ten entrances you still go through this procedure every time you arrive. You show your paper that says 10 entries to get and electronic card and It takes quite long to charge these cards for each customer. It would be a lot faster to just "buzz" people through the turnstile than do what they do with these cards.
Lockers use 50cent pieces. Changing rooms and showers are separated for men and women - but there are only few individual changing cabins (at least on the men side) and those who are there are quite small. The Changing area and the showers are dimly lit, quite old and not welcoming.
The basins are in good shape and the pool hall is a nice place to be. The (salt)water was a tad too warm for my taste though.
Overall a nice small pool (that could do with some modernizations) that you can go to when the weather doesn't permit to swim in the ocean.
