New York is one of the world's busiest and most exciting cities, but it can also be terribly expensive. Here are some hints to help you navigate New York on a budget.

Get a good guidebook, preferably one that includes a subway map and other transit information.

Walk whenever possible. Many residents and tourists firmly believe that New York is best seen on foot. Walking also allows you to avoid the inevitable traffic jams that occur at all times of day.

Take the subway. New York's subway system is more than 700 miles long and runs 24 hours a day. Look into the Metrocard, which is available in either pay-per-ride or unlimited use options.

Take the bus. It may be slower than the subway, but you'll get to see more of the city if you are traveling aboveground.

Ride a bike if you dare. Cycling in New York is probably best left to experienced riders, but there is a network of bike paths covering the city, and lots of bike messengers zoom around Manhattan throughout the day.

Share a taxi. While a cab ride in New York can be expensive, a group of people may find this to be a convenient, relatively affordable option.
