St. Mary's Alpine Park
About this Park
St. Mary’s Alpine Park is a wilderness paradise for the experienced backcountry traveller. Numerous lakes and tarns are tucked against rugged granite cliffs and surrounded by tundra and lingering snowfields.
Seven creeks drain the lakes, resulting in numerous waterfalls and cataracts, some as much as 150 metres in height. Experienced hikers, willing to expend considerable effort in bushwhacking and route finding should visit this protected area where few if any people will be encountered.
