This is a question that often comes up for first-time rafters in Northern California. Whether you choose to raft the South Fork or the Middle Fork of the American River, you will have a great time. People often focus on the “class” of the river in order to determine whether they are going to see “more” or “bigger” rapids. This simply is not true. The higher the “class,” the more TECHNICALLY difficult the rapid; size is not necessarily a factor. A quick presentation of river classification will be helpful in determining which type of river is right for you.

First and foremost, one should note that the single highest rapid in a river determines the classification of that river. For example, if a river full of class II rapids has one class V rapid, then the river is automatically a class V. While several different classification systems exist, the I-VI numerical system is the most common in the United States.

- Class I: easy, slight rippling, moving water with almost no obstacles – Class II: rippling water, some whitewater, swift but few obstacles, which require minimal navigation – Class III: moderate, guide is typically required, tall rapids, powerful hydraulics, maneuvering needed for set-up but not within rapids – Class IV: moderate-advanced, guide is required, tall rapids, powerful hydraulics, maneuvering needed within rapid in order to remain safe – Class V: advanced, intense hydraulics, technical lines needed to navigate rapids, previous experience required, physical fitness a must. Professional guide a must. – Class VI: un-navigable. Can be a trickling stream or a large waterfall.

Commercial whitewater rafting generally ranges from class II to class V. When reviewing the list, the difference between class III and class IV is nominal, when it comes to the power of the rapid. The true difference is in the difficulty of navigation, i.e., whether you will be required to paddle in order to help safely navigate. While some class IV rapids tend to be more powerful, the difference is primarily in the duration of maneuvering.

If river classification is the only criteria important to your decision-making, you are done. The South Fork is class III and the Middle Fork is class IV. However, there are other considerations to be aware of. The South Fork offers a whole host of features that the Middle Fork does not have. These features may or may not be part of your decision-making process but are worth noting in order to be aware of your options, if nothing else.

The South Fork of the American River is one of the most rafted rivers in ALL of the United States, year in and year out. It is popular for many reasons: it’s easy to get to, it offers one-day and two-day rafting options (so it is doable in a weekend), there are many campground options, and there are an abundance of rafting companies operating on this river. Additionally, the rapids are fairly consistent, and the class III rating promises predictable hydraulics that get the blood pumping but are manageable for wide age ranges (7-years to 70+). The shuttles to and from river put-in and take-out are not overly long and tiresome. Access to the riverside is relatively easy, there are no hikes and or rough trails to get the gear to the river and back to the vehicles.

The South Fork truly accommodates a wide variety of people. Additionally, the water flow is predictable, the season is relatively long (May to October), the river valley is interesting given the Gold Rush history, and it makes for an affordable vacation.

The most famous rapids on the 21 miles South Fork are the Triple Threats, Meat Grinder, Trouble Maker, Satan’s Cesspool and Hospital Bar.

The Middle Fork has many of the same features as the South Fork. It is dam controlled, so the flows are relatively consistent. Its season is a bit shorter than the South Fork’s. The Middle Fork does have larger hydraulics, more technically challenging rapids, a waterfall (don’t worry, you walk around it), and the famous Tunnel Chute. Given that the river is more remote, the shuttle ride is longer (albeit still tolerable). Most companies raft it in a day, although the two-day wilderness option is available from some outfitters. No campgrounds or convenience stores are located nearby; once you get into the river canyon, you are there until the 20+ mile trip is through. The Middle Fork definitely steps up the difficulty a notch, but also offers longer stretches of calm water as well as a unique, remote beauty.

Some of the famous rapids on the Middle Fork are Tunnel Chute, Panic alley, Chunder, Cartwheel, Duck Soup and Parking Lot. The Middle Fork also includes a portage around Ruck-a-Chucky Falls, which means that you have to exit the raft and carry the gear waterside.

Which river is best for you? It truly depends on what you want. As a rafting provider, I find that most of my guests tend to gravitate toward the convenience of the South Fork, but each river truly has its own set of challenges and appeal. And of course, the changing water flow is always good for a new adventure!
