Drifting, originally a primitive way of wading, it originated from the Eskimo kayak and the Chinese bamboo raft. It became a real outdoor sport and began to develop after World War II. Stream tracing is an expedition from the downstream to the upstream of a canyon stream to overcome obstacles in the terrain, the source of poor water and the summit of mountain climbing.

Drifting and tracing streams belong to the movement of the brave, moving forward in the turbulent and gentle currents from time to time, deducing wonderful moments in the struggle against nature.
