High Park is a wonderful 400 acre park just north of the lakeshore and Sunnyside Beach. There are lovely gardens, little bridges, ponds, and waterfalls, and some more secluded trails. The best way to explore High Park is to start at the Bloor Street entrance and run along until you come across a little foot path or single track jetting off the main route. The park is randomly hilly. There are various road and trail options in the park. Following the outer perimeter trail is ~5 km. There are options for additional trails in the park. Great views of the Toronto skyline!
