Whitewater Rafting Rapid Classification Guide

An international scale that rates individual rapids from class 1 (easy) to class 6 (nearly impossible) is used in all our river descriptions.

A rapid may vary in terms of time from just a few seconds to 20 seconds or more.

REMEMBER! This scale is subjective. Rapids can change in difficulty seasonally and as quickly as overnight! This scale is meant only as a guideline for how easy or difficult a rapid, river or river trip may be. It is best to speak with one of our knowledgeable reservationists to find out what the river level may be like at the time when you would like to raft with us, and assist you in choosing the best trip.

CLASS I RAPIDS

“Chinook definition: Very relaxing.”

Gentle, moving water. Very small waves requiring little or no maneuvering.

CLASS II RAPIDS

“Chinook definition: You may get splashed.”

Regular waves, easy to see, may reach 3 to 4 feet in height. Avoiding rocks, river bends or other obstacles may require simple maneuvering.

CLASS III RAPIDS

“Chinook definition: You will get wet!”

Large, continuous series or sets of waves, some in excess of 6 feet. “Holes” or “hydraulics” may be present, and can be run or avoided. Small drops, ledges or waterfalls may be present. Scouting the rapids is suggested for all but the most experienced of river persons.

CLASS IV RAPIDS

“Chinook definition: You’ll get soaked… like a 9 or 10 on the ‘fun scale’!”

Confused and erratic waves or holes. Large obstructions need to be avoided in what are referred to as “must moves.” Risk of injury if swimming without benefit of a raft! Very difficult and scouting is required.

CLASS V RAPIDS

“Chinook definition: Adrenaline junkies only!”

For most people, class V goes off the “fun” scale and enters the “kinda scary” scale! Very challenging for even the most experienced river persons. High risk of capsize or injury. Limit of navigation and scouting is essential.

CLASS VI RAPIDS

“Chinook definition: Niagara Falls in a barrel!”

Virtually non-navigable, or navigable only at particularly favorable river levels.

White water rafting brings the heartrate up and sm White water rafting brings the heartrate up and smiles all around. The Kananaskis River delivers so much fun and excitement! We’ve been working with Chinookrafting to bring family friendly (and Covid friendly) trips this season. This river slices right between Calgary and Banff, making it an easy day trip for those wishing to have a different type of thrill. 
.
In the late 1800’s, Logs used to bounce down this river as the Kananaskis was used to bring wood from the mountain slopes to the Bow River to help supply Calgary.

Kananaskis is the best name isn’t it?! Don’t forget to ask your guide where it comes from?
