Caving in Glacier National Park
Generally, entry into caves is not permitted. Cavers must
apply to the Superintendent for entry into any cave.
The Nakimu Caves lie between upper and lower Cougar Valley
in the Selkirk Mountains, just west of Rogers Pass on the Trans-Canada Highway.
The Caves are reached by hiking three to four hours up and over a mountain pass
from the highway, an elevation gain of over 800 metres.
Visitors’ efforts will be rewarded by the unique experience
of descending, by the light of headlamps, into the dark labyrinth of the caves.
Numerous passageways and grottos, totaling 5.9 km in length, contain intriguing
natural features such as soda straws, rock fluting and moon milk. Short steep
scrambles and uncertain footing are characteristic of the cave experience.
