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.
