River-, Lake- and Sea Cruises Great Wall of China (China).

China and India are the most populous countries on the planet. Formerly communistic, China turned very capitalistic. This large country and great culture offers many superb touristy sites with the Great Wall (the only structure visible from the moon) being the most famous. Beijing, Shanghai, Guilin and Xian in particular are worth a visit. China has excellent, very fast trains and travel has become really easy. Hong Kong and Taiwan are listed separately.

The Great Wall of China needs no introduction. It served to protect mainland China from Mongolian invaders and took decades to build. Now it is the only structure that can be seen from the moon.
