A Journey Through The Soo Locks: The Ultimate Boat Tour Experience

Nestled between Michigan’s Upper Peninsula and Ontario, Canada, the Soo Locks stand as a marvel of engineering and a gateway to the Great Lakes. These historic locks, located in Sault Ste. Marie, Michigan, allows ships of all sizes to traverse the 21-foot drop between Lake Superior and the lower Great Lakes. Whether you are a history buff, an engineering enthusiast, or simply seeking a unique travel experience, a journey through the Soo Locks is one to remember.

A Glimpse Into History

The Soo Locks trace their origins back to the early 19th century when the natural rapids of the St. Marys River presented a significant obstacle for Great Lakes shipping. Prior to the locks' construction, cargo had to be unloaded, transported around the rapids, and then reloaded onto another vessel. In 1855, the first lock system, known as the State Lock, was completed, revolutionizing maritime travel and commerce. Today, the locks are operated by the U.S. Army Corps of Engineers and remain one of the busiest in the world, facilitating the passage of over 7,000 vessels each year.

Experiencing the Locks Through Soo Locks Boat Tours

A visit to the Soo Locks offers several ways to witness their grandeur, but perhaps the most immersive way is by taking a Soo Locks boat tour. These guided excursions provide an up-close experience of this incredible engineering feat, allowing passengers to travel through the locks just as freighters do. As the boat enters the lock chamber, travelers can watch and feel the vessel being raised or lowered by the changing water levels.

One of the highlights of the boat tour is the detailed narration provided by knowledgeable guides. They share fascinating insights into the history of the locks, how they operate, and their significance to Great Lakes commerce. Passengers learn about the types of cargo transported through the locks, from iron ore to grain, and hear stories about some of the famous freighters that have passed through these waters.

Most boat tours last between 90 minutes to two hours, providing plenty of time to enjoy the views of Sault Ste. Marie, both on the U.S. and Canadian sides. Along the way, guests can also see various landmarks, including the International Bridge, historic waterfront buildings, and occasionally, massive Great Lakes freighters navigating their way through the locks.

For those who appreciate maritime history and engineering, these boat tours offer a rare opportunity to gain firsthand experience of how the locks function. Many visitors describe the moment the gates close behind the vessel and water levels shift as both thrilling and awe-inspiring.

The Engineering Marvel

The locks operate using a gravity-fed system, where water is transferred between chambers without pumps. The process is remarkably efficient: when a ship enters the lock, massive gates close behind it. Water is then either added or removed to match the level of the adjacent lake, allowing the vessel to continue its journey. The largest of the locks, the Poe Lock, is the only one large enough to accommodate the biggest Great Lakes freighters, which transport essential cargo such as iron ore, coal, and grain.

Beyond the Locks: More to Explore in Sault Ste. Marie

While the Soo Locks are the highlight of Sault Ste. Marie, the area offers many additional attractions. The River of History Museum and the Museum Ship Valley Camp provide deeper insights into the region’s maritime past. Visitors can also explore the picturesque waterfront, enjoy local cuisine, or take a short trip to the Canadian side of Sault Ste. Marie for even more sightseeing opportunities.

A journey through the Soo Locks is an unforgettable experience, blending history, engineering, and natural beauty. Whether you choose to cruise through the locks or watch from the observation deck, witnessing this incredible system in action is a testament to human ingenuity and the enduring importance of the Great Lakes shipping industry.
