In 1883, three Canadian Pacific Railway construction workers discovered something incredible tucked into Alberta’s Rocky Mountain range.
On an eastern slope, they found a cave that contained hot springs.
Today, those pools are called the birthplace of Canada’s national parks. Banff National Park, the first in the country and the third in the world, grew from just a small basin into a massive destination spanning 2,564 square miles.
But if you think all that’s worth seeing of the beautiful northern attraction is the turquoise-blue waters of Lake Louise, think again.
This is the cave and basin where Banff began.
