Paris' weekly entertainment pamphlets, Pariscope and L'Officiel des Spectacles, list up-to-date information in French on every imaginable outdoor activity. Look for listings on randonnées pédestres (hiking in groups), cyclisme (biking), escalade (rock climbing), plus parachuting, canoeing, squash, tennis and swimming, among others. Among uniquely Parisian activities, it's hard to beat drifting lazily down the Seine (or the Marne, the Oise or any of the city's canals) in a canal boat. Rentals are available year-round.
