The capital of Norway has been at No. 1 since 2006, U.S. News & World reports. You had better be a high roller to set foot here — even a bottle of water will set you back $6. But if you do have the extra cash, the city is a haven for foodies as well as outdoorsy types. From sailing to museums, opera to hiking, there’s something for everyone.
Budget travelers: The Guardian suggests walking to Vippentangen port, where you can take a ferry trip around the nearby islands, then hitting up Vigeland Park for a cheap pint.
