From the cable cars up in San Francisco to the New York City subway, across the pond on the London Tube to Japan's speeding Bullet train, public transit is a way to see the sights as you travel this summer.
Public transportation is a good option for exploring a new destination — and you'll save money! Most cities have a transit system available, so here are some tips for a better trip.
Looking to expand your itinerary? The local buses or trains may connect you to further destinations, so see where else you can go without driving a car or flying.
Mass transit can get you to most must-see places while on vacation. And don't forget the must-do activities that are walkable or bikeable.
