The only rotating boat lift (boat elevator) in the world, the Falkirk Wheel is an engineering marvel.
If you wanted to connect two bodies of water that were at vastly different heights, how would you do it? In Scotland, brilliant engineers built a rotating boat elevator called the Falkirk Wheel – and we got to ride on it while we were living in Edinburgh this summer!
Why Build the Falkirk Wheel?
The Falkirk Wheel links the Union Canal with the Forth and Clyde Canal. This makes it possible to travel between Edinburgh and Glasgow – Scotland’s two largest cities – by boat. Originally, a series of 11 canal locks connected these two canals, but they fell into disrepair and were dismantled in 1933. The Falkirk Wheel re-created this link, in a much more efficient way!
Riding the Falkirk Wheel
At 115 feet high, the Falkirk Wheel is an impressive piece of architecture as well as engineering! My kids were excited to get on the boat, even though (on a summer weekend) it was so packed that we couldn’t even sit together.
We waited for the wheel to rotate into an upright position, and then our boat entered the lower gondola:
Riding a boat elevator is a strange sensation! You know how you feel the elevator go up and down? That doesn’t happen in a boat lift, because the water holds everything steady! It feels like you aren’t moving at all. Then you look out the window and realize how tiny the trees, people, and houses have suddenly become!
If you look at the photo above, you can see the system that keeps the gondola level with the ground even as the wheel rotates around. Those Scottish engineers thought of everything!
At the Top of the Falkirk Wheel
Once you reach the top of Falkirk Wheel, you make your way through an aqueduct. Then you travel through the Rough Castle tunnel to enter the Union Canal. You can see the two remaining locks that are needed to enter the canal in the photo above. I was a little disappointed when we didn’t actually drive into the canal. I have a thing for canal locks, and this double look looked especially intriguing.
Instead, we made our way back through the tunnel to the aqueduct and then into the gondola to make our way down. See the houses way down below?
We did get to ride back down with the little red boat we ran into at the canal locks. I guess they were just waiting for us to show up so that they could ride down with us. My kids were pretty excited about the little white dog they had on board! The little dog on the boat also had a much better view than we did sitting on a crowded tour boat. I you get the chance to ride on a private boat on the Falkirk Wheel, take it!
Going down is just like going up. You don’t realize you are descending at all, until you look up…
And see the other half of the Falkirk Wheel ascending!
Is Riding the Falkirk Wheel Worth the Price?
Honestly, I’m on the fence about this. The Falkirk Wheel is an engineering wonder, and it’s pretty neat to experience the non-motion of riding it. If you can ride it on a small boat, I say go for it! I felt like the large tour barge didn’t allow for a very good view unless you were lucky enough to get one of the front seats. I was in the very back in a middle seat, where you can’t see very well.
Whether you choose to ride or not, the Falkirk Wheel is well worth a visit. Watching the wheel is an experience in itself, and there is plenty to enjoy from the ground.
How Does the Falkirk Wheel Work?
The 35 meter (115 feet) diameter Falkirk Wheel stays balanced because the two gondolas always weigh the same thanks to Archimedes’ Principle. This perfect balance also means that very little power is required to run the wheel. A smaller wheel system (see the top photo in this post, or the video below) keeps the gondolas parallel to the ground as they rotate. The wheel rotates 180 degrees in five and a half minutes, using only the same amount of electrical power that would be required to boil eight kettles of water.

An Engineering Challenge for Kids
The Falkirk Wheel is an excellent way to introduce kids to the idea of moving boats between bodies of water. If they had to move a boat up 82 feet to reach the next body of water, how would they do it? Can they build a small replica of the Falkirk Wheel?
