Why the biggest dam in the world isn't always easy to see
Catching a glimpse of the world's largest dam is not as easy as you might expect.
The Three Gorges Corp strictly controls the expressway leading to the dam outside Yichang city and the site itself, citing security concerns.
But the policy also gives the company a monopoly on all tourism activities via its 'designated' travel agencies, which charge 168 yuan per person for an hour-long tour of the site.
The fee includes transport, a Chinese-speaking guide and the chance to view the dam from two lookouts, one far above the massive structure and another on the same level but a few hundred metres away.
Neither viewpoint is close enough to see the cracks in the dam, which domestic media says are so big a fist can be shoved into them.
Tourists could previously view the dam from below, beneath an arc of water gushing through the sluice gates, but tour operators scrapped this stop from the itinerary because of construction work.
Despite reports that armed helicopters, armoured vehicles and bomb-defusing robots have been posted at the dam to guard against potential attacks by terrorists or Taiwan, none of this hi-tech weaponry was evident during a recent visit.
