The Ottawa River is a legendary destination for rafting enthusiasts, home to some of the most thrilling rapids in North America. In this blog, we highlight the best of the best – those wild stretches that make this river a world-renowned spot for whitewater rafting. Whether you’re new to rafting or a seasoned paddler, this guide covers the top rapids you should add to your adventure list, including what to expect and why they stand out.
1. Garvin’s Chute – A Must-Ride Classic
One of the most iconic rapids on the Ottawa River, Garvin’s Chute offers a perfect balance of excitement and accessibility. Located on the Middle Channel, it’s known for its steep drop that creates a heart-racing plunge – a feature that makes it a favourite among OWL Rafting guides and returning guests alike.
- Rapid Difficulty: Class IV
- What to expect: A straight shot down a tongue of smooth water, followed by a foamy explosion
- Best for: Thrill-seekers looking for a signature white water moment
OWL Rafting includes this rapid, which is only run by the high-intensity sport rafting trips at specific high water levels, so you’ll get expert instruction before tackling it. It’s a rite of passage for many who fall in love with whitewater rafting on the Ottawa River.
2. Coliseum – The Big Show
Coliseum earns its name from the stadium-like shape of the surrounding landscape, opening up to reveal this massive rapid. It’s arguably the most famous rapid in the area – a bucket-list experience for anyone river rafting in Canada.
- Rapid Difficulty: Class III-V, depending on season and water levels
- What to expect: Huge standing waves, complex manoeuvring, and lots of adrenaline
- Best for: Experienced paddlers and adventure junkies
This rapid comes later in the full-day rafting route and is often the highlight of the trip on the main channel. At certain high water levels, our Jet Boat is used to provide safety for the medium and high intensity trips. Low intensity takes a different route. Some guests even say they return year after year just for the Coliseum, making it a defining feature of OWL Rafting experiences.
3. Butcher’s Knife – Quick and Technical
Don’t let the name scare you – Butcher’s Knife is a rapid that demands respect, but it’s also incredibly fun. It’s one of those rapids that seems to change every time you run it, which is why OWL Rafting guides love introducing guests to it.
- Rapid Difficulty: Class III+
- What to expect: Gorgeous granite wall on the right side with embedded quartz that makes the rock quite sharp – hence the name.
- Best for: Intermediate paddlers and up, or beginners on guided trips
This rapid adds technical variety to the otherwise wave-heavy Ottawa. It’s a favourite for people interested in trying rafting while staying safe under the guidance of a professional.

4. The Lorne (Black Chute) – Power, Precision, and Pure Thrills
The Lorne, also known as Black Chute, is the first major rapid on the Main Channel of the Ottawa River after the channels split. Its smooth, glassy tongue accelerates paddlers straight into the Garburator — a fast, powerful, and highly surfable hydraulic also nicknamed the “Space Shuttle.”
- Rapid Difficulty: Class IV
- What to expect: A thrilling main drop, surfable waves, and iconic features like the Washing Machine, Moby Dick, Bus Eater, and Wa-Ki-Ki
- Best for: Experienced paddlers and thrill-seekers
To the right lies the churning Washing Machine, while downstream you’ll find the mighty Bus Eater and the playful Wa-Ki-Ki surf wave.
5. McCoy’s Chute – The Legendary Gateway
If there’s one rapid that captures the Ottawa River’s wild beauty, it’s McCoy’s Chute. Known as the gateway to the river, this is the first big test on most full-day rafting routes. Right at the start, rafts charge straight into Phil’s Hole: a powerful wave hole that delivers an instant shot of adrenaline, before carrying on through the rest of McCoy’s thrilling features and stunning scenery.
- Rapid Difficulty: Class IV
- What to expect: A powerful drop, crashing waves, and some great photo opportunities
- Best for: Anyone up for a challenge early in the day
From this point on, you’re committed – and that’s part of the excitement. OWL Rafting guides prep every group with safety briefings and paddle practice, making sure even nervous beginners feel ready to take it on.
