Wet stone breathes cool air into the mouth of Rat’s Nest Cave as a small rope line clicks into place above you. In the half-light, the mountain closes in; the cave pulls you down an 18‑metre rappel into a narrow corridor where the rock wants to press back. For four concentrated hours, this guided trip trades wide alpine views for the intimate geology of subterranean chambers — the Grande Gallery, the Grotto, and the Laundry Chute — where crawling, wriggling and short technical descents are the point.

Wet stone breathes cool air into the mouth of Rat’s Nest Cave as a small rope line clicks into place above you.

For four concentrated hours, this guided trip trades wide alpine views for the intimate geology of subterranean chambers — the Grande Gallery, the Grotto, and the Laundry Chute — where crawling, wriggling and short technical descents are the point.
The cave sits beneath Grotto Mountain, formed in Mississippian limestone and sculpted by glacial melt and underground streams over millennia. Local Stoney Nakoda and early mining communities knew these passages long before they became a commercial experience; today guided trips focus on low‑impact exploration and safety. Expect rooms with flowstone drips, fossil fragments, and tight passages that force deliberate, careful movement.
Practically: participants hike uphill 30–40 minutes to the entrance, then spend roughly four hours underground. Guides provide helmets, lights, harnesses and instruction; you'll rappel 18 m and navigate squeeze sections that push flexibility and composure more than technical rock skills. Small-group limits (up to eight) and a requirement for moderate fitness keep the itinerary focused and safe.
Book with weather and physical restrictions in mind: not recommended for people with significant spinal or heart issues, or later‑term pregnancy. Wear grippy boots, layered synthetic clothing, and bring water and snacks for the hike in — the cave itself is cool, wet and demanding. The reward is a rare, vertical subalpine world that dares you to look down and keep moving.
challenging.
4 hours (approx).
Participants should have moderate to good fitness — able to hike uphill 30–40 minutes and perform crawling, climbing and an 18 m rappel.
You’ll spend roughly four hours on the Adventure Tour, including the underground travel and technical sections like the rappel and squeezes.
No formal experience is required — guides teach rope techniques and supervise all technical moves, but you should be comfortable with heights and confined spaces.
Not recommended for travelers with significant spinal or heart conditions or for those beyond first‑trimester pregnancy; ability to hike uphill and perform moderate exertion is required.
Shared tours are limited (up to eight); minimum two participants apply and tours may be cancelled with a full refund if minimums aren’t met.
Rat’s Nest Cave is formed in Mississippian limestone and was known to local Indigenous people and early settlers; guided tours converted it into a managed visitor experience with conservation in mind.
Operators run small groups and enforce strict Leave No Trace rules inside the cave to prevent damage to delicate formations and protect subterranean ecosystems.
Canmore Cave Tours operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
