The European-style park in Plateau Mont-Royal is one of the city's oldest and most popular. Illustrating the traditional dual identities of the city's populace, half the park is landscaped in the formal French manner, the other in the more casual English style. A central lake is used for ice-skating in winter, when snowshoe and cross-country trails wind through trees. In summer, these trails become bike paths, and tennis courts become active. An open amphitheater, the Théâtre de Verdure, features free outdoor theater, music, and tango dancing. The northern end of the park is more pleasant than the southern end (along rue Sherbrooke), which attracts a seedier crowd.
