Does the world really need more towers? Local authorities apparently thought so, opening the Macau Tower Convention & Entertainment Centre in 2001. In addition to exhibition and convention space, it contains restaurants and shops, but the crowning glory is the 330m (1,083-ft.) tower, with an observatory about 223m (731 ft.) high -- the equivalent of 61 stories. Because admission to the outdoor observation deck and indoor lounge is exorbitant by Macau standards, I personally think you are best off coming for a meal in the revolving 360 Cafe. However, thrill seekers take note: The indoor observation lounge has a glass-floored section that gives the illusion of standing on thin air. But real daredevils will want to tour the observation deck's outside ramparts with the safety of harnesses and ropes, which costs MOP$588, including a CD of your adventure and a T-shirt. Other ways to have fun with Macau Tower: climbing the mast (a 2-hr. ordeal) or bungee jumping 233m (764 ft., listed in the Guinness World Records as the "highest commercial bungy jump").
