Dubai has cheap and plentiful taxis, as well as a metro which runs through the financial and residential areas of the city. But this is a land of excess, so while you can make use of these rather 'pedestrian' transport modes where appropriate, you should also take the chance to get around in less conventional ways. Take a 4x4 safari out to the desert, which you can do while bouncing around in a jeep. Or you can jump into a hot air balloon at sunrise to see the desert spread out before you, like a seemingly infinite blanket of golden sand. Or, for the ultimate in decadence (this is Dubai after all!), hop a 15- or 25-minute flight in a luxury helicopter up above the city. But if you just need to get from Point A to Point B, consider buying a gold-plated Porsche.
