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.
Hiking or walking is an activity practiced in all kinds of terrains and is not restricted to age, gender or physical fitness.
As in every task, there are various levels of difficulty, which can be surpassed gradually as experience is gained. The routes are divided into four types of difficulty: relaxed, medium, steady and difficult.
