It’s not every day you get front-row seats to one of the most powerful natural phenomena on Earth—unless you happen to be in New Brunswick. The Bay of Fundy, which forms a dramatic, saltwater border between New Brunswick and Nova Scotia, is a place where water quite literally moves mountains (or at least moves around them). With tides that swing over 50 feet between high and low, this isn’t just another pretty view—it’s Earth flexing its gravitational muscles.
Flood the Senses
From sticky buns to sea caves, from reversing rivers to renewable energy, here’s everything you didn’t know you needed to know about the most mesmerizing bay in the country.
Tides That Slap: How the Bay of Fundy Makes Waves
Let’s start with the star of the show: the tides. The Bay of Fundy boasts the highest tides in the world. On a good day, water levels can shift up to 56 feet—about the height of a five-story building. And it happens twice a day. Every day.
What’s behind this tidal drama? A combination of gravitational forces, atmospheric pressure, and the bay’s iconic shape—narrow, deep, and funnel-like—conspire to create a sloshing effect so powerful it stuns even seasoned scientists. It’s like the ocean got caught in a very large, very persistent traffic jam—and we get to watch it surge forward and retreat on repeat.
Spring Forward, Neap Back: Why the Moon Is Basically in Charge
The moon plays a starring role here, too. During spring tides (which, confusingly, happen twice a month and not just in spring), the sun and moon align during the new or full moon, pulling the tides even higher. Conversely, neap tides occur during quarter moons, when their forces compete, resulting in a less dramatic tidal range. Throw in wind conditions and barometric pressure, and the Bay becomes a live-action science experiment with ocean-sized variables.
Why You’ll Only Catch One High Tide a Day
Unlike many coastal spots that offer two high tides and two low tides a day, the Bay of Fundy generally serves up just one of each. It’s all about resonance: the natural rhythm of the incoming tide aligns perfectly with the bay’s dimensions, amplifying its effect. Think of it like timing a jump on a trampoline—when it syncs up, you go higher.
Tidal Bore: When the River Says "Wrong Way"
One of the Bay’s most underrated spectacles is the tidal bore, where a wave of incoming ocean water travels against the current of a river. Moncton’s Petitcodiac River offers one of the best views: a standing wave that charges upstream like it owns the place. You can even surf it, if you’re bold enough (and have good balance).
Clean Power, Big Potential
This much kinetic energy doesn’t go unnoticed. The Bay of Fundy is also a hotspot for tidal power innovation, with underwater turbines harnessing the relentless current. The Cape Sharp Tidal project and others like it are working to turn the bay’s natural power into renewable energy, offering clean electricity and a glimpse at the future of sustainable infrastructure.
Where to Catch the Tide in Action
-
Hopewell Rocks: Possibly the most Instagrammable spot in New Brunswick, these iconic rock formations are exposed during low tide, allowing you to walk on the ocean floor. Six hours later, you’re kayaking past the same rocks, now partially submerged.
-
Fundy National Park: With trails that dip into tidal zones and rise up for sweeping views, this is your spot for a hike with drama. Watch the landscape morph over the course of a few hours—nature’s version of a quick change.
-
Cape Enrage: Name aside, this place offers nothing but serene views and scientific curiosity. With a lighthouse and interpretive centre, it’s perfect for both your inner poet and inner nerd.
-
Saint John: Don’t miss the Reversing Falls Rapids, where the Saint John River literally changes direction thanks to the tide. There’s nothing subtle about it—and that’s the point.
When to Go (Because Timing is Everything)
If you want the full Fundy effect, time your trip around the new or full moon, when spring tides take centre stage. These are the days when water levels reach peak drama—and when your jaw is most likely to drop. Check local tide charts to plan your arrival at either high or low tide and catch the before-and-after contrast that has wowed visitors for centuries.
Fun(dy) Facts: 9 Reasons This Bay Deserves a Spot on Your Bucket List

That’s not a wave—that’s a wall of water.
2. It Moves 100 Billion Tons of Seawater Twice a day
More than the outflow of all the world’s rivers combined.
3. It’s a Paleontologist’s Playground
Dinosaur fossils dating back 200 million years line the bay’s cliffs. Jurassic Park, but real.
4. It’s Whale Watching Heaven
Spot finback, minke, and even the elusive North Atlantic right whale.
5. It’s Bird Central
Every summer, 2 million semipalmated sandpipers use the Bay as a rest stop.
6. The Shape is Everything
The bay’s unique funnel shape is what gives it that insane tidal range.

Perfect for unplugging and pretending you’re in a Maritime version of Survivor.
8. You Can Surf a Tidal Bore
Bring a board and ride a river backwards. Because why not?
9. It’s UNESCO-Worthy
The Bay of Fundy is a Natural World Heritage Site contender—and deservingly so.
Final Splash
The Bay of Fundy doesn’t need to compete with sandy beaches or five-star resorts—it’s in a league of its own. It’s raw, rhythmic, and unapologetically powerful. Whether you’re a hiker, a history buff, a science geek, or someone who just wants to say, “I walked on the ocean floor,” this is a trip that will raise your standards—and your eyebrows.
