Class I Rapids - Moving Water Over Shallow Riverbed »
Class I rapids are defined by moving water with small waves that tug at the boat in a downstream flow - it's a relaxing way to spend the day. Rafting trips on class I whitewater are generally labeled as "scenic float trips". Most rivers have stretches of calm Class I water, creating a pleasant break between larger rapids.
Understanding What Makes a Rapid: Rapids are formed when running water moves swiftly over a shallow bed, around and over obstacles, or is constricted by narrow walls. Each of the classifications contains one or any combination of these. Many river trips that are great for starters contain Class I - III whitewater rapids. See the list further below if this is the kind of rafting trip you are looking to start out with.
