An absolutely fantastic time!! Our guide Abby was incredible! She made us feel like family. I really can't say enough about her. Fantastically wonderful. The cave is beautiful and we are going back for the Wild Tour that will allow us to see even more!
What a hidden gem! (Pun intended) it was a total unexpected surprise. The caverns are beautiful and quite large, and we found it interesting that they are still exploring new areas of the cave currently! We really enjoyed the tour guide even though it was her first week on the job, she did a wonderful job explaining and giving us the tour. 10/10 would recommend! It is a must visit if in the area!
