One of many signature landmarks of New York City, the Brooklyn Bridge is also one of the oldest suspension bridges in the country. Its six-lanes (and one pedestrian and bicycle walkway) span the East River, connecting Manhattan to Brooklyn. Walking across the bridge remains a tourist pastime.

Some visitors decide to skip the bridge in favor of other attractions, but if you're short on money, this truly is one of the best ways to experience the city and to get a unique view of either borough. You can take the A or C train to the High Street stop in Brooklyn and stroll along the bridge back to Manhattan. It takes about 30 minutes to walk from one side to the other, and it's free to visit.
