Bluespring Caverns is a natural wonder. Our hour-long boat tour allows you to explore and experience the majestic underground. Passages and water-courses are illuminated by the pocket of light that follows your tour boat through darkness.

Glimpse elusive cave creatures.

  • Rare, blind cavefish
  • Blind crayfish in constant search for food
  • Spotted red-orange salamanders
  • Solitary bats hanging on a high ceilings

Wet Periods

Visit during a wet period, and you will hear and see the power of the underground river; though many of its creatures will have retreated to quieter areas.

We absolutely loved this cave. We were the only ones on the boat tour and the guide was super nice and full of information. We will come back and do cave kayaking!
