Spain
I think that the Lido is fantastic. I am not a great swimmer but I loved the sea water pools here. One is really large with volcanic rocks in it. The water is deep enough to swim but you can stand up anywhere in the pool. No nasty big waves appearing to submerge your head. It only costs a couple of pounds to get in and you can stay all day.
