 By way of the Congress Street Bridge, Children's Wharf is a short walk from South Station, one of Boston's principal transportation hubs.The wharf is one of the more easily accessible locations on the Harborwalk, a newly established walking tour akin to the Freedom Trail, intended to take advantage of the change in landscape brought about by the Big Dig.The wharf takes its name from Boston Children's Museum (founded in 1913), which moved here from Jamaica Plain in 1979.
