I visited the Qingtongxia Yellow River Grand Canyon during off-peak travel. Building such a project in the 1950s and 1960s was truly a feat. My personal experience was that the boat route B was the best, offering many beautiful views, such as the Yellow River Gorge, the Gorilla Head Rock, and the Buddha Head Rock. The 108 Pagodas are quite unique. Overall, I had a great experience.
