Very cool piece of architecture. One of eight lift locks in the world. This one states that it is the tallest. Don't just walk around at the bottom. Be sure to explore all the stairs and go up to the top. It's totally worth it. There are historic signs posted that help you appreciate it for what it is. Definitely a must stop place.

Really interesting and well maintained place! Parks Canada has a building beside the lift locks, full of historical information. There is a little movie theater, a museum, and staff available for any questions you might have. There is also a washroom! Surrounded by well maintained public areas, it's a nice place for a picnic... at the very least. If you're lucky, you'll get to see the locks in action as boats traveling up and down the river use the locks...as they were when they were first engineered and built! Apparently there are only 8 of these locks in the world! Kids and adults alike will learn and enjoy visiting here! There is also a gift shop.

Pretty impressive structure. It’s also a great place to hang out and have a picnic along the river. Peaceful and relaxing. Walk up the stairs from either side of the structure to get to the second level where the boats, kayaks and other water vessels are loaded or unloaded. It’s fun to watch how this giant structure works. The two lifts work in tandem, meaning when one rises, the other lowers.

One of the greatest waterways structures, that was the # one in the world for years. It works using water and gravity , the best practical example of the Lift Lock is a Seasaw ! You can find many good videos online about how a lift lock works, but remember do not mix the lift lock with Lock !!!!! The Peterborough Lift Lock , has a great picnic area around the lift lock, very good visitor centre with great services, also there is a two hours cruise that passes through the lift lock. If you like engineering structures, do not miss this !!!!!

Visit June 26, 2018. Nice visitors centre and park area around this fascinating structure and marvel of engineering. Trent-Severn waterway Lock #21 is uplifting. Great spot for a picnic or moving a marine vessel up or down 19.8 meters.

Beautiful place, especially in the fall. Locks shut down for the winter after Thanksgiving weekend but still beautiful place to walk around.

Beautiful park surrounding the largest hydraulic lift locks in the world. Built over one hundred years ago this is a functioning piece of Canadian history.

Offered interactive free activities for kids, some excellent historical static displays explaining the lift lock development and construction. Nice little movie about the Trent-Severn construction. Staff were very friendly and informed.
