Green transportation choices provide you with the keys to the kingdom as you travel. You can walk off the calories of that buttery croissant as you explore Paris. Or better understand Chinese culture as you park your Flying Pigeon bicycle amid 100 others in a Beijing parking lot dedicated just to bikes. A marine ferry takes longer than an airplane to get you to Alaska, Mykonos or Nova Scotia, but you have a good chance of seeing dolphins and eagles, reading a book or two and chatting with the crew. You'll save money, your waistline and fossil fuel emissions by taking the greener road.

Step 1:

Get out of the car and walk once you arrive. The very greenest transportation choices are the non-motorized ones-bicycling and walking. Fortunately, both are also the best way to see a city. Pack comfortable shoes so you can explore without foot fatigue.

Step 2:

See if your lodging provides free bicycles for guests, recommends Irene Lane of Greenloons, a company that advises families on ecotourism travel choices. If not, rent a bicycle from a shop: many carry electric bikes that'll help you tackle hills or long rides even if you're not in top biking shape. In addition, see if your destination has a bike-sharing system that's accessible to tourists. For a small fee, these sharing systems allow you to pick up a bicycle from a nearby bike station, ride it to your heart's content for an hour or two, then return it to any other bike station in the city.

Step 3:

Take public transit once you arrive at your destination—most major transit systems now post maps and schedules online on multilingual sites, allowing you to familiarize yourself with the system in advance. In addition, some systems have applications for smart phones so you can get up-to-date information as you travel.

Step 4:

Move between cities using buses, trains and ferries, which tend to be greener than automobiles and airplanes—buses are considered more efficient than cars because their emissions are shared by several dozen people. If you have to fly or drive to get where you're going, take the most direct route and see if you can go green by proceeding on foot or bicycle once you arrive.

Step 5:

Rent an electric car if you must travel by vehicle and focus on green driving behaviors. Plan an efficient route, inflate your tires properly and remove unnecessary cargo to improve fuel efficiency and reduce the vehicle's carbon dioxide emissions.
With the green transportation choices, you can enter the ancient kingdom.（　）
