Turns out, the Devil’s Quarry is planted 333 feet below Cardwell Mountain in Tennessee — where cavers are summoned from far and wide.

And it’s no wonder why these brave adventurers travel to make this trek. Because even though the risks involve high-ladder climbs and a gaping hole in the center of the Earth, the reward is spectacular — and magnificently rare.

Tenacious cavers on The Crucible will scale underground canyons, cross Devil’s Quarry, and climb a high winding route to The Monument Pillar — a formation known by many but witnessed by few.

Have you ever traveled back in time — to the Quaternary Age, when wild lynx left their mark 333 feet below the Earth?

Guts and Glory takes you there; to a plot on the Earth’s timeline that transforms you into the cave’s original explorer.

It takes courage to time travel. But it takes real guts to traverse the cave via handlines, high twisting climbs, and ladders.

But as the original explorer, you’re prepared to give what you have to uncover this underground glory. And that glory, well, it comes in many different forms — from The Great Extension, the Monument Pillar, and the Blue Mud Mountain, to the Rock of Ages and undiscovered passages.

Thousands of years in the making, it’s all there — waiting to be uncovered; waiting to meet its first explorer.

It’s a badge of honor—a grind for glory. And a daredevil’s holy grail. This is the (sunken) peak of all adventure—the time where your courage is both tested and rewarded with sights so spectacular yet magnificently rare.

Tenacious cavers on our Into the Dark Overnight Adventure will scale underground canyons, cross Devil’s Quarry, and climb a high wind to The Monument Pillar — a formation known by many but witnessed by few.

When it’s all said and done, you’ll march on into the dark. And rest beside other brave cavers to hum the tune of a warrior’s lullaby, knowing you put in a hard day’s adventure.

This is the night where everything is tested: Your courage, your strength, and most importantly, your trust in the cave.

Lights Out is the overnight adventure that, physically, requires the best of you. But the rewards wonder and awe are far worth completing the challenge.

From The Great Extension, the Monument Pillar, and the Blue Mud Mountain, to the Rock of Ages and undiscovered passages, this is the night you’ll learn most about the cave — and even yourself.

You’ll understand the need for a cave campout when it’s all said and done. Because after you make this tiring journey, driving home just won’t feel like an option.
