Gorge Underground 1

The Gorge Underground is unlike any other adventure you have ever been on! Join us as our guides lead you into the darkness of the Gorge Grotto, through the mountainside for a full hour-long adventure under the earth's surface. Paddle your way through the grotto in your own kayak as our guide leads the way while explaining the history of the cavern and how it came to be flooded.  Be sure to look out for the newly relocated rainbow trout! 


$45.00 plus tax per person.  Reservations are STRONGLY RECOMMENDED! 

Tours book up rather quickly, so making your reservations in advance will ensure you get to go on adventure on the day and time you want to go. Even in the winter season, it's important to book ahead so that our guides know what tours are going out.

(Yes, we are open year round - come check it out!)


Full-priced adventures include all gear needed (boat, paddle, life jacket, helmet, headlamp).

You can also bring your own boat and paddle and we only provide the helmet, headlamp and life jackets (if available) for a $10 savings; give us a call in the office for more details.


We suggest you bring a sweater or jacket as the temperature does drop to about 55 degrees once you are inside. Waterproof camera is a great idea! 


Participants must be at least 40lbs and no more than 300lbs.  Each participant is required to wear a helmet and personal flotation device (provided) throughout the entire tour. Participants must be able to safely get in and out of kayak.

Participants must arrive at the Thrillsville office 30 min PRIOR to the tour time.  At the office we will verify waivers and give you tickets and driving directions, and you will drive about 4 miles up to the mine for your tour.

Each participant is required to sign a waiver.  You can complete this online to expedite the check in process upon arrival!  (Click the link in the confirmation email or click the button at the bottom right hand side of each page on our website!)

Participants cannot be under the influence of drugs or alcohol while on adventure. (Arriving impaired may result in your adventure being canceled without refund.) 

No special skills are required.


We understand that life happens and can sometimes get in the way.  For that we have developed the following policy.  To cancel your reservation and receive a full refund (minus 5% for processing), we require at least 24 hours notice PRIOR to your reservation date.

Cancellations on the same day of your reservation will NOT receive a refund.


Tour times will differ from office hours. Please call or message social media pages to confirm office hours. Tour schedule can be viewed by clicking 'book online' on the right.

I especially enjoyed seeing the quartz pyrite on the ceiling. I also was impressed at how clear the water was.
