Classification of Rapids
To categorize rivers by difficulty and adapt the route to the skill level of the group, there are six difficulty levels, ranging from Class I (easy) to Class VI (extremely difficult).
Class I – Very Easy – Calm water. Obstacles are easy to avoid with little practice. Mainly used for introducing canoeing and kayaking.
Class II – Beginner – Small rapids that are easy to navigate. Ideal for beginners and families.
Class III – Intermediate – Irregular rapids with moderate waves and obstacles. Accessible to beginners, suitable for families or groups seeking some excitement.
Class IV – Advanced / Athletic – Rapids not visible in advance. Significant movements and steep gradients.
Class V – Expert – Very challenging rapids that require a high level of skill.
Class VI – Extreme / Unrunnable – Rapids considered extremely dangerous and unpredictable, often only attempted by teams of experts under exceptional conditions.
