Join us September 17-20th 2026 for an unforgettable freshwater adventure in the St. Lawrence River, one of North America’s most unique and historic dive destinations.
The St. Lawrence offers clear water, gentle current drift dives, and an incredible collection of well-preserved shipwrecks ranging from 19th-century wooden schooners to modern steel vessels. Many wrecks sit upright and intact, making them perfect for exploration, photography, and buoyancy practice, all with excellent visibility for freshwater diving.
September is an ideal time to dive the river. Water temperatures are comfortable in wetsuits, boat traffic is lighter, and visibility is often at its best. We’ll base ourselves in the Thousand Islands region, diving with experienced local operators who know these sites inside and out.
This trip is a great fit for certified divers who enjoy wreck diving, relaxed drift profiles, and a bit of history beneath the surface. After diving we’ll have plenty of time to enjoy the charm of the river towns topside after a day on the water. For the diehards who can’t get enough diving, shore dives are also plentiful.
Because of the depth of many of the wrecks, participants are required to have a deep specialty certification or proof of 5+ dives deeper than 60 feet.
