Three Gorges Dam (三峡大坝, Sānxiá Dàbà)

No — independent access has been restricted since the mid-2010s for national security reasons. All visitors must register at the official Three Gorges Tourist Center in Yichang, show ID, and board the designated tourist buses. You cannot drive yourself, walk onto the dam, or arrange a private tour that bypasses this system. The tourist bus loop is well-organized and the restrictions are absolute.

For engineering enthusiasts and people who want to see the largest construction project in human history: yes, as an overnight trip. Day trip from Wuhan: only if you are determined and leave at 6:00 AM. For casual tourists: the Yellow Crane Tower + East Lake + Hubei Museum in Wuhan is a better use of limited time. The dam is impressive but visiting it consumes an entire day and involves a lot of bus time.

Yes — Yangtze cruise ships (Chongqing to Yichang, 3–4 nights downstream, 4–5 nights upstream) pass through either the five-stage ship locks (3–4 hours transit) or the ship lift for smaller vessels (40 minutes, 113 m lift). The cruise experience of the dam is significantly better than the land-based tour — you experience the scale of the locks from the water, which is the dam's intended perspective. Cruises cost ¥2,000–8,000+ depending on ship class and season.

The reservoir holds 39.3 cubic kilometers of water — enough to cover the entire country of Switzerland in 1 meter of water. The weight of the reservoir (39.3 trillion kg) is so massive that NASA scientists calculated it slightly altered the Earth's rotation and shifted the North Pole by about 2 centimeters. The dam's 32 turbines generate electricity for an estimated 60–100 million people, primarily in eastern and central China.

The Three Gorges (Qutang Gorge, Wu Gorge, Xiling Gorge) are among the most famous natural landscapes in China — steep limestone cliffs rising from the Yangtze through misty valleys. The dam raised the water level by up to 113 meters, which tamed the rapids and widened the river, reducing the dramatic verticality of the gorges. They remain beautiful but are less vertiginous than before 2003. The scenery is best appreciated from a multi-day cruise, not from the dam tourist loop.

HSR from Wuhan (2 hours, ¥120–180), from Chongqing (2.5 hours, ¥160–220), or from Changsha (3 hours, ¥200–260). Yichang also has an airport (YIH) with flights from Beijing (2.5 hours), Shanghai (2 hours), Guangzhou (2 hours), and Chengdu (1.5 hours). Yichang is well-connected and the HSR station (Yichang East, 宜昌东站) is the gateway for dam visitors.

Environmental: altered the Yangtze's ecosystem, contributed to the functional extinction of the Yangtze river dolphin (baiji), and changed sediment flow affecting the Yangtze Delta. Social: displaced 1.3 million people. Geological: the added water weight may increase seismic activity in the region. Archaeological: submerged 1,300+ known archaeological sites. These are documented in the dam's own exhibition hall and have been extensively studied. The dam's defenders point to flood control (the 1998 Yangtze floods killed 3,600+ people) and renewable energy generation (replacing an estimated 50 million tons of coal annually).
