Rafting in Nepal

International classification of Difficulty

Rivers and rapids for rafting purpose are classified into 6 categories based on the difficulty. First being easy moving water and sixth being the extremely difficult where commercial trips are not recommended. The class 6 is recommended only for expedition purpose.

Class 1: Easy. The rivers or rapids of this class are very easy. There is easy moving water with occasional small rapids. There are few or no obstacles.

Class 2: Moderate. In this class of this class are very easy. There is easy moving water with occasional small rapids. There are few or no obstacles.

Class 3: Difficult. In these rivers, rapids are with irregular waves and hazards which need to be avoided. In this class of rapids, more difficult maneuvering is required but routes are normally obvious. Scouting from the shore is occasionally necessary.

Class 4: Very difficult. In these rivers the rapids are large and long having dangerous hazards that require careful maneuvering. In these rapids scouting from the shore is often necessary and rescue is usually difficult. Turbulent water and large irregular waves may flip rafts. In the event of mishap, there is significant risk of loss, damage and / or injury.

Class 5: Extremely difficult. In this class the rapids are longer and very violent with several hazards. Powerful confused waves that come continuously makes route-finding difficult. So scouting from the shore is essential. Precise maneuvering is critical. Rescue is very difficult or impossible and in the event of a mishap there is a significant hazard to life.

Class 6: Nearly Impossible. This class of river rafting might be run by a team of experts at the right water level, in right conditions with all possible safety precautions, but still with considerable hazard to life. Commercial running is not recommended.

One of the problems of the International Classification is that the majority of rapids come under class 3 and class 4. In fact there is a vast difference within an easy 4 and a hard one. In Nepal, the power of the Himalayan Rivers, steepness of the rivers and boulders has created unique features. Hence the use of + and – Class has been made for the purpose of being more definitive.

1,       2,        3,        3+,       4-       4,       4+        5-,       5,       5+,     6  

The classifications of the difficulties are based on typical water volumes for the month of November when the rivers of Nepal are calm. Earthquakes, landslides, floods, etc. may completely change a river, river courses and make it easier or harder. A rapid of Class 5 or may calm down to Class 1 next year.
