Piscine Pontoise (19 rue de Pontoise, Paris) (Metro Maubert Mutualité) – located within an Art Deco building, this is a sports complex whose main attraction seems to be its swimming pool (an asset during the Summer, since there are no beaches in the Paris area). The pool has kept up its charm and special features (2 floor balcony changing rooms, wrought iron railings and numerous pillars), but at the same time has evolved into a modern sports complex (which includes squash courts, a fitness center, and a sauna). Admission: €4.50 For an additional €15.90, one can sign up for swimming lessons. Open daily, times vary. Call for hours: +33 01 55 42 77 88.
