I´ve been looking forward to this one. 50 Meter Basin, open air and situated at the edge of a great…read morePark with a nice big patch of Grass to lie down after swimming to soak in some sun. Awesome. In theory.
And don´t get me wrong, it´s all there. A great lawn for sunbathing and a 50 meter pool that is in decent shape despite it´s age. There are also some other basins, diving boards and a volleyball field. And to finish this - the staff were even reasonably friendly.
On the negatives side of things there is the Building that houses the changing cabins, the wardrobe check, the showers and a little Bistro. Awful. Truly awful. Smelly, old, unwelcoming, dirty and not up to modern standards at all.
So if you want to enjoy the great pool, the nice lawn and all that - you first have to pass through this little house of horrors to get there (and if you want to leave again too, of course). Would I recommend Piscine de la Grenouillere? If you can change into and out of your swim-gear in your car - yes.
Practical info: bathing caps aren't mandatory but surfer-short type swimwear is forbidden. No Lockers but a wardrobe check.
