Rat’s Nest Cave is a constant 5°C (41°F) all year.  Why is that?  Because caves reflect the mean annual temperature, so no matter what the outside weather is like, it’s always pleasant inside the cave.  Like most alpine caves, it is cool in summer, mild in winter.  In 1987, the cave was designated a Provincial Historic Site.  Access to the cave is restricted to protect the delicate environment within. The Rat’s Nest Cave has over 4 km of explored passage, and lies under Grotto Mountain near Canmore, Alberta.
