Scuba diving in the 1000 Islands.

Shipwrecks & Scuba Diving

See for yourself why so many divers call this area the “Caribbean of the North.”

Discover the watery graves of more than 1,800 ships, some of which date back to the War of 1812. You’ll also spot varied wildlife, billion-year old underwater mountains formed during the Ice Age, and much more. 

The conditions are ideal with the extreme clarity of the water, thanks to zebra mussels, which have cleaned up the river allowing for an amazing 70 feet visibility. 

The water temperature between the surface and deep waters are usually within a couple degrees of each other, making this a comfortable dive. Add in thick granite walls, 100-feet chasms and over 200 shipwrecks to explore and you can see why divers from all over the world travel here. 


Underwater Mountains

You can uncover the mysterious history of lost ships in the 1000 Islands. Or simply experience the amazing marine life that lives amongst the billion year-old underwater mountains left to us from before the flood of the Ice Age. 

Divers come from all over the world to dive into our underwater seascapes with granite walls that plunge from hundreds of feet deep to a few feet of shoals.


For many years, the St. Lawrence River served as a main shipping route between the Great Lakes and the Atlantic Ocean. 

Whether because of weather or shallow waters, many ships ran aground and sank.

Now, hundreds of years later, you can bring that history to life. 

Whether you’re a beginner, intermediate, or advanced diver, you’ll love traveling back in time and discovering our underwater world. 

Here are some of the notable shipwrecks that have found their final resting place in the 1000 Islands:
  • AE Vickory – 1861 wooden three masted schooner, sunk August 17, 1889
  • The America – steel drill barge, sunk June 20, 1932
