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 per person


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!
