Take summer fun to a higher level with Treetop Trekking. Treetop Trekking is Ontario's original zip line aerial park experience. Come spend an adventurous day at one of our 3 Ontario zipline aerial parks located at the Ganaraska Forest near Peterborough, Horseshoe Valley near Barrie and at Deerhurst Resort in Huntsville. Make it a summer you will never forget by exploring the trees on zip lines, swinging bridges, monkey cables, Tarzan swings and much more during a 3-hour tour. Courses vary from Beginner to Expert so there is something for everyone aged 9 and up (5+ Barrie). Looking for something really different? School and Group rates, Night Treks, Kids Courses, Treehuggin' and Team building programs are available at some parks. Reservations are required. Season Passes available.
