Another fascinating dive site in China is the submerged section of the Great Wall. This area was flooded to create a hydroelectric station, and the history was sacrificed for the progress. The dive season is brief, from April to June, when the water's depth is between 7 to 11m and the temperature hovers around 13°C. Then, the site becomes unavailable as the water deepens. Further at a depth of 60m lies another submerged town. Photo credit: www.uw360.asia scubadiving
