The Slate Islands Provincial Park is our crowning jewel on the waters of Lake Superior—11 km (6.8 miles) south of Terrace Bay, off the Canadian north shore of Lake Superior.
The Slates are an island chain with a storied history of logging, mining, and early indigenous settlements—home to a resilient herd of woodland caribou and sheltering one of the world’s largest shatter cone!
Are dark skies on your bucket list? The Slates are a perfect spot to stargaze, with the milky way and northern lights visible during the right time of year.
Experience one of the most incredible journeys in Northern Ontario—make the once in a lifetime trip to the Slates!

The Slate Islands are home to a beautiful herd of boreal woodland caribou that migrated via ice bridge, back in 1907. The caribou, while calm and passive around humans, are still shy by nature, but do still make the odd appearances for lucky visitors.

Since coming to the islands, the caribou have been relatively predator-free for more than a century. On average, there have been an estimated 100 caribou on the islands, but the population does vary and has spiked as high as 600!

The Slates also maintain a healthy population of wildlife—there are snowshoe hare, beavers, foxes and birds/shorebirds (herring gulls and great blue heron)—over 50 species of wildlife and 250 species of unique plant life!



The Slate Islands are believed to have formed almost 1 billion years ago when a 3 km-wide (1.9 miles) meteorite struck the area creating a 32 km (19 miles) wide impact zone. The impact uplifted a large portion of the land that later formed the Slate Islands. With the sudden and massive release of energy—like those from the meteorite or even nuclear explosions—the shock waves gave way to a very large shatter cone on the islands.
Reaching up to 10 meters (33 ft.) high, the Slate Island’s shatter cone is one of the largest in the world!
