Terry Fox Mile 0 Site is a memorial that adds a useful stop to the St. John's things-to-do map. Waterfront marker where Terry Fox began the Marathon of Hope in 1980. It is worth listing for travellers because it gives the destination a more specific texture than another general viewpoint or shopping street.
Plan it as a focused visit rather than a whole-day anchor unless you already know this is your special interest. Check the official site before going for current opening hours, tickets, and seasonal closures, then pair it with nearby sights in St. John's so the detour makes sense on foot, by transit, or by taxi.
