Fodor's Expert Review Parc Montsouris

This 38-acre park on the southern edge of the city is one of Paris's best kept secrets. Home to an enormous variety of flora and fauna, as well as a small rose garden, one can stroll or jog around the hilly footpaths or lounge and picnic on a number of giant lawns. There are free playgrounds for children and a small lake with ducks and other waterfowl. If you're feeling especially energetic and adventurous, cross Boulevard Jourdan and explore the campus of the unique and historic Cité Internationale Universitaire de Paris. The campus is home to a variety of architectural wonders, both modern and historic, which house visiting professors and students from around the world.
