There’s a certain thrill in standing along the St. Marys River in Sault Ste. Marie, Michigan, watching massive freighters rise or sink effortlessly before your eyes. Known as the Soo Locks, this engineering marvel connects Lake Superior to the lower Great Lakes, making it one of the most important shipping passages in the world. Each year, over 7,000 vessels pass through, carrying everything from iron ore to grain, ensuring the lifeblood of commerce flows smoothly through the Midwest.
But the Soo Locks are more than a functional wonder—they’re a living piece of Great Lakes history, a family-friendly attraction, and a reason to explore one of Michigan’s most charming northern towns. Whether you’re a first-time visitor or returning for another season of ship watching, there’s a lot to discover, do, and taste while you’re here.
The History and Importance of the Soo Locks
The story of the Soo Locks dates back to the mid-1800s when navigating the rapids of the St. Marys River was treacherous and nearly impossible for large vessels. In 1855, the first lock was completed, transforming shipping on the Great Lakes forever. Today, the locks are operated by the U.S. Army Corps of Engineers and remain free to use for both commercial and recreational boats—a rarity for such an essential waterway.
Standing on the observation deck, you’ll be just feet away from 1,000-foot freighters, tugs, and tour boats as they make their way through. It’s an up-close view of modern maritime power, combined with the awe of Victorian-era ingenuity. And it’s no small feat—the locks handle over 80 million tons of cargo annually.
Are There Any Campgrounds Near the Soo Locks?
Yes—and they’re worth the stay. Sault Ste. Marie offers multiple campgrounds within minutes of the locks. Aune-Osborn Campground, for example, is a favorite for RV travelers and tent campers alike, with many waterfront sites offering direct views of passing ships. Imagine sipping your morning coffee while a freighter glides silently past—no ticket required.
Other options include private campgrounds with full hookups, cozy cabins, and nearby state parks like Brimley State Park, just a short drive west. Staying close to the locks lets you catch those late-night or early-morning passages, when the air is quiet and the lights on the freighters shimmer against the water.
