There's a long tradition of people flocking to the mountains for the long weekend, but Sunday, one of the world's most popular mountain towns reached its breaking point.
Lake Louise was so busy they had to restrict access.
Highways remained open, but due to overcrowding late Sunday afternoon, the RCMP and Parks Canada advised park visitors not to visit Instagram darling Lake Louise.
They even devised an entry requirement: only residents and people with hotel reservations at the site could enter Lake Louise.
Every other visitor to Banff National Park was out of luck.
It's not the first time that access has been restricted. In September 2020, the same thing happened.
The restrictions don't appear to have lasted very long, however.
The area was re-opened to everyone by Sunday night, although there has been no update on social media about whether or not that will change Monday.
