While there are no mountains to climb within the city, you can still rejoice in the closest thing to a literally heightened experience—climbing Lupu Bridge. Pick a clear, sunny day and hop in a taxi to the bridge that straddles the Huangpu River.
The climb up the steps is easy—no safety harnesses are necessary and guides will leave you to make the summit on your own. Once you reach the top, take in the vast panoramic view, which now includes a good shot of the future site of the Shanghai World Expo 2010. Remember to bring your camera along and take advantage of the great many snapshot opportunities.
