Epic Adventures Since 1992

Your Time is Precious.

Make It
Extraordinary.

Most people come to the Rockies for what's above, but only the curious few discover what lies beneath. Rat's Nest Cave stretches four kilometres under Grotto Mountain — carved from ancient limestone and shaped by glaciers. Home to fossils, pictographs, and formations that took millennia to grow, it's an experience that stands the test of time.

Whatever you came to the Rockies for, this will be the part you talk about when you get home.

Real Adventure

You're heading into a real, undeveloped natural cave — no walkways, no fixed lighting, no handrails. You'll be dressed in high-quality caving equipment and teamed up with one of our experienced cave guides for an experience that is uncommonly wild.

Year-Round, Rain or Shine

Mountain weather is unpredictable - unless you're IN the mountain. The Cave is always 5°C. There's no rain, no wind, no snow and no sun, so we can explore the cave any day of the year. TL;DR: We almost never cancel because of weather, so plan with confidence.

A Complete Experience

Most guests are surprised by how much there is to discover down there — the geology, the fossils, the stories your guide brings to life around every corner. The physical challenge is real, but so is the sense that almost anyone, with the right guide and the right attitude, can do this.

Caving experience was amazing!!!! Our guide Annie was very informative and helpful as well as a lot of fun! This cave system is quite large and plenty to explore. We did the Adventure tour which was well worth the value offered. Highly reccomend!!

This was amazing! Our guide was fantastic, the communication leading up to the tour was very clear, and we felt well prepared. The hike was challenging but beautiful and well worth it! Our experience in the caves was fantastic. Very safe but still a moderate level of difficulty to get around which made it very fun. My kids (11 and 14) were very nervous but loved every minute of the cave tours. They even challenged themselves by doing some of the tight squeezes. The caves were beautiful to see. I highly recommend this tour for anyone travelling to Canmore or Banff.

(Translated by Google) Had a really good tour with Jon! He was able to explain everything to us about the animals, nature, and of course the cave! Very interesting, knowledgeable, and we had some nice conversations with him. The cave view was also fun to do, especially because very little has been altered in the cave. So that does mean some climbing, and you do get quite dirty from the mud and wetness. No problem though, most of it is absorbed by the overalls you are given! 5/5! (Original) Hele goede tour gehad met Jon! Hij kon ons alles uitleggen over de dieren, natuur en uiteraard de grot! Zeer interessant met veel kennis en hebben leuke gesprekken gehad met hem. De cave aanzicht was ook leuk om te doen, met name omdat er weinig is aangepast aan de grot. Betekend dus wel wat klauterwerk en je wordt er redelijk vies van de modder en nattigheid. Geen probleem meeste wordt opgevangen door de overal die je krijgt! 5/5!

A once in a lifetime experience! We had an incredible time doing this tour and doing the squeezes through the cave. Our guide was exceptional and was very knowledgable about caving and answering all of our questions. I would 10/10 recommend this experience if you are in the Banff/Canmore area.

Went with our 11 and 14 year old boys. None of us had ever been in a cave. Of note, this is a vertical cave --> requires descending down and then climbing out. Our guide HyunHo was spectacular. he was friendly, patient, great at explaning and teaching, taught us about caving and the cave itself. Amazing experience, tons of fun. Would strongly recommend for anyone even thinking about it. Got the kids interested in exploring more caves in the future. Easily worth the cost for this lifelong memory.

We had Emily as our tour guide and she did an absolutely fabulous job! We chose the explorer tour as a 2nd year wedding anniversary gift to ourselves and it did not disappoint one bit. Although it was a steep and sometimes slippery hike, it was well worth every bit. I cannot thank Emily enough for giving us such a fun and unforgettable experience :) she was so helpful, easy to talk to and even laughed at all my husband's jokes! We felt incredibly safe and secure our whole trek and would definitely do it again. Can't recommend enough.

My father (early 60's) and I (28) booked this trip looking for something adventurous to do during our trip to Banff, and this cave expedition did not disappoint! While it's listed as a tour, it is much more involved than that - it's truly an underground cave spelunking adventure and is more physically demanding than either of us expected, but is manageable for anyone strong enough to pull their own body weight and with full body mobility (we had an active couple in their late 60's with us, and we've been told people in their 80's have managed). Our guide Jon was fantastic - he kept the journey going at a good pace while keeping an eye on everyone, prioritizing safety, and ensuring we pushed ourselves without pressuring us to do more than we were comfortable with. He also shared facts and stories at breaks throughout, and there were plenty of opportunities for photos (I recommend just bringing a smartphone if you want pics, there's no space for traditional cameras). It felt very real and was just the right amount of a challenge - not too difficult as to be truly scary, but just hard enough that you felt proud of yourself for finishing and worn out by the end of the journey. For anyone with an adventurous spirit looking to test the waters of underground caving, I can't recommend it enough!

One of the best caving tours that you'll love so much and will never forget. My group was a full 8 max people who I never met before and we all bonded so well and were a great team and good support for each other in the cave. Our tour guide was Emily was she was really great and very knowledgeable on everything and sees everything like a hawk to make sure your safe and are well looked after. I highly recommend to do adventure tour which is 6 hours and 4 or more of the hours your in the cave. The hike is spectacular and beautiful to the cave entrance and the whole cave adventure was awesome and sometimes challenging which made even better. Definitely check these guys out and do the tour you won't regret it trust me and I came all the way from spruce grove Edmonton to do the tour and the others were from utah and west Virginia.
