Montréal is named for the 232m (761-ft.) hill that rises at its heart -- the "Royal Mountain." Joggers, cyclists, dog walkers, skaters, and others use it throughout the year. On Sundays, hundreds congregate around the statue of George-Etienne Cartier to listen and sometimes dance to impromptu music. In summer, Lac des Castors (Beaver Lake) is surrounded by sunbathers and picnickers (no swimming allowed, however). In wintertime, cross-country skiers follow the miles of paths and snowshoers tramp along trails laid out for their use. The large, refurbished Chalet du Mont-Royal near the crest of the hill provides a sweeping view of the city from its terrace and the opportunity for a snack. Up the hill behind the chalet is the spot where, tradition says, de Maisonneuve erected his wooden cross to establish the first colony here in 1642. Today the cross is a 30m (100-ft.) high steel structure visible from all over the city, illuminated at night.
