One of the great pleasures of Boston is that it is easily walkable, its original narrow streets winding their way amongst the skyscrapers. Unfortunately this also makes driving a nightmare. Fortunately the city’s superb network of public transport run by the Massachusetts Bay Transportation Authority (MBTA) is at hand. This comprises subway lines (including the country’s oldest subway tunnel), buses and ferries. Visitors planning on using public transport extensively should purchase a 1-day, 7-day or monthly travel pass known as a CharlieCard ( www. mbta.com).
