This one is not hidden in the literal sense, but few people notice how awesome the Dubai Frame is—located in Zabeel Park, the 93-metre-wide and 150-metre-tall frame, actually 'frames' Old and New Dubai so you get to see all the city's iconic landmarks within its borders. The structure is hard to miss, but since its significance is not known by most tourists, people miss out on the experience. There is also a viewing platform at the very top named The Sky Deck, where a 25-metre panel made entirely from glass, called The Golden Bridge, is sure to get your adrenaline pumping if you are brave enough to walk across it.
