What is the Underground Jeep Crawl?

It's a family oriented Jeeping adventure that's different from any other Jeep ride you've been on. The route is entirely underground in an abandond silica mine. Any Jeep brand vehicle with a 4-LO transfer case can participate. We've designed the approximately 4 miles of underground route so that even a bone stock vehicle can participate and still get a bit of a thrill. Experienced guides help navigate you through the mine so you won't get lost in the nearly 200 acres of caverns, and, when your done with the route there is still plenty to do. Not to mention you'll be meeting and making new friends!

What does it cost?

Price is per vehicle.

$40 One day entry into the event and guided tour through the underground trail.

Do you support a charity with a portion of the profits?

Yes, a portion of our proceeds will be going to Intrepid Fallen Heroes Fund a non-profit organization that provides support to United States military personnel and the families of US military personnel lost in service, those who are severely wounded as well as for veterans. We are also contributing to the Crystal City Underground to help in the clean up efforts after it was devastated by the flood in late 2015. We have also organized volunteers to put in many man hours preparing the mine to reopen.

What does the fee cover?

Your fee gets you entrance into the event and access to the only underground Jeep trail in America!
