Canada carries more fresh water than any other country and a good portion of it sits in lakes so deep the bottom has never been properly measured. Most never show up on any travel list despite being among the most extraordinary bodies of water anywhere on earth. These ten are worth the effort for anyone willing to look past the obvious choices.
Great Slave Lake, Northwest Territories

614 meters deep and sitting in the Northwest Territories where most people never go. The clarity of the water in certain sections makes the depth genuinely hard to believe from a boat floating on top of it.
Quesnel Lake, British Columbia

One of the deepest fjord lakes in the world at around 511 meters in central British Columbia. The blue green color reads as edited in every photograph and looks exactly the same when a person is actually standing beside it.
Adams Lake, British Columbia

Goes down to around 457 meters in the Thompson Okanagan region. The surrounding terrain falls steeply into the water on multiple sides and the resulting views sit in a different category from most lake scenery in the province.
Cultus Lake, British Columbia

Clear water, easy to reach, and backed by mountains that make the setting work at any time of year. A reliable option for anyone who wants the deep lake experience without committing to a serious journey to get there.
Okanagan Lake, British Columbia

Narrow and long through an orchard valley dropping to around 232 meters. The water gets warm enough by summer for genuine swimming and a well established wine region fills out whatever time gets spent away from the water.
Shuswap Lake, British Columbia

Four separate arms spread across the region creating more shoreline than most people expect from a single lake. Depths reach around 160 meters and the scale means returning visitors regularly find sections they have never explored despite coming back for years.
Lake Superior, Ontario

Around 406 meters deep and wide enough that the far shore disappears completely on most days. Waves build here the way they do on open ocean and the word lake starts feeling like the wrong word once a person has spent any real time at the edge of it.
Kootenay Lake, British Columbia

Runs 104 kilometers through the Rocky Mountain Trench going down to around 150 meters. A free ferry cuts across the middle in what turns out to be one of the longest free crossings anywhere in the world with mountain views running the entire way.
Atlin Lake, British Columbia

Altitude over 700 meters, intensity about 283 meters, and very few people out there in any year. The water comes from the glacier, the views dominate every road, and the area is just undisturbed in a way that most remote destinations can’t handle anymore
Babine Lake, British Columbia

Stretches 177 kilometers making it the longest natural lake entirely within British Columbia with depths reaching around 186 meters. Salmon runs through the connected waterways draw serious wildlife attention and timing a visit around them produces something most travelers never get to see.
