In V i e t n a m, you can find guides that row their sampan boats with their feet. This hands-free technique prevents them from back pain and getting tired. The rowers can also navigate quickly.
You can take a boat tour through the Tam Cốc-Bích Động and enjoy the 3 cave systems, the limestone karst scenery, the paddy-fields, and the beautiful natural and cultural landscape. This area is part of the Tràng An Scenic Landscape Complex, a UNESCO site.
