These sports are considered adventure travel par excellence. Extreme ski consists of going down quite a steep mountain with nothing but your skis. People practicing this activity have to use this technique in its maximum expression, giving priority to safety rather than to downhill speed.
This is one of the most complete sensations that the human being may feel.
Through diving, man could visit the bottom of the sea, see a sub-aquatic world, stroke fish and visit legendary shipwrecks, feeling completely safe and adapted to the water environment.
In order to practice this activity, it is not necessary to be in great shape, or to have a well-defined swimming style.
