Nakimu Caves, Cave system in Glacier National Park, British Columbia, Canada.
Nakimu Caves is a cave system in Glacier National Park extending through about 6 kilometers of limestone. Cougar Brook has carved passages and chambers throughout the formations over countless years.
Charles Deutschmann discovered the caves in 1904 and built wooden walkways, staircases, and a floating bridge to guide visitors safely through the system. His work opened the caverns to wider exploration.
The Secwépemc people named these caves Nakimu after the sounds of underground water, which resembled grumbling spirits in their language. This name reflects their spiritual connection to the natural features of the land.
Access requires a three-hour hike with 800 meters (2,600 feet) of elevation gain and is limited to experienced cavers with special permits. Visitors should be physically prepared and bring proper equipment.
The cave walls display moonmilk formations, which are calcium carbonate crystals growing on bacteria and resembling cauliflower heads. These rare mineral structures form under the specific damp conditions deep within the caverns.
