White Water Rafting: Age, Weight and Health Requirements

Age requirements for white water rafting

The minimum age depends on the river class.

On Class I and II courses (calm water, small waves), most operators accept children from age 6. This includes gentle runs like rafting in Fort William or the calmer stretches of Scottish rivers. For Class III rapids (irregular waves, strong current), the minimum rises to 8-12 depending on the operator. Class IV and above typically requires 14 to 16 years minimum.

Minors always need a signed parental consent form. Some operators require an adult in the same raft for children under 12. No upper age limit: participants aged 65 to 70 regularly run Class II and III rivers. The beginner's guide to white water rafting covers what to expect on your first run.

Weight and build for rafting

The maximum weight sits between 100 and 130 kg depending on the operator. The most common limit is 110 kg. Beyond that, it's an equipment issue: life jackets and wetsuits have a maximum size, and the number of seats in the raft may be adjusted.

No strict minimum weight in Europe. In the US, Coast Guard regulations require a minimum of 23 kg (50 lbs) for approved life jackets. In practice, any child who meets the minimum age requirement will have the necessary weight.

If you weigh over 100 kg, mention it when booking. Most operators accommodate without issue. For the budget side, the rafting cost breakdown covers pricing by country and duration.

Do you need to know how to swim for rafting?

Being able to swim 25 metres and submerge without panicking is the universal requirement across all operators. Even with a life jacket, falling into a Class III rapid means a few seconds underwater.

On Class I rivers (calm water, no rapids), some operators relax this rule. But that's the exception. When in doubt, treat the 25 m as non-negotiable.

Health conditions and contraindications for rafting

Four situations are incompatible with rafting:

• Pregnancy: systematic refusal by all operators, regardless of stage
• Serious heart conditions: risk from exertion, cold water (8 to 14 °C depending on river and season) and physiological stress
• Uncontrolled epilepsy: seizure risk in an aquatic environment
• Severely reduced mobility: you need to hold yourself in the raft, paddle and climb back in if you fall out

Controlled asthma, type 1 or type 2 diabetes and mild back problems are not contraindications, but must be disclosed before departure. The operator adjusts the route or your position in the raft.

A medical certificate is rarely required in Europe for recreational rafting. Some operators request one for Class IV and V runs.

River classes: which rafting level suits your profile?

The international river classification runs from I to VI. It determines the actual access conditions.

In practice, commercial runs focus on Class II and III. That's where you'll find the accessible courses, like rafting in the Gorges du Verdon (45 to 90 €) or rafting in Interlaken (87 to 153 €). For a first run, a Class II or III trip with a guide is more than enough.
