Easy. Passive relaxation and sightseeing — cruises for example. No physical activities. Good for older people.

Normal. Active tours. You don’t have to be a sportsman, but you need to be strong enough to ride a snowmobile or go hiking in the mountains.

Advanced. Get ready for a challenge — long trekking with a heavy backpack on the shoulders, rafting along mountain rivers.

Hard. Professional training and perfect physical fitness are required. The level involves climbing to the tops of the mountains (above 3000 meters), freeriding and North Pole diving.
