The huge Three Gorges Dam hulks away upstream. The world's largest due to length (2.3km) rather than height (101m), it isn't the most spectacular, but is worth a peek. You can't walk on it, but there's a tourist viewing area to the north. The view from the south is much the same, and free. Take a bus from the long-distance station to Máopíng (茅坪; Y15), but get off at Bālù Chēzhàn (八路车战). Alternatively, take bus 4 from the ferry terminal to Yèmíngzhū (夜明珠; Y1) then change to bus 8 (Y10), which terminates at Bālù Chēzhàn. Tours (Y150 inclusive of admission) also leave at 8.30am and 1pm from Hubei Xiazhou International Travel Service.
