Patagonia has a great deal of geographical faults with remarkable geothermal and volcanic activity. These features explain the existence of various sources with hot spring waters. The diversity existing in this area of South America ranges from warm water issuing from the ground, rich in minerals, to geysers with boiling water.
Rafting is a team sport, in which all the crew members in the boat row and position themselves in a coordinated manner in order to balance their weight when going through the river rapids and keep themselves afloat.
The standard number of people allowed on the boat is from six to eight crew members, depending on the boat size.
Rafting beginners are recommended to remain in the center of the boat. Those who are somehow experienced and prefer to row may stay in front, whereas the most experienced generally stay at the back.
