Our tour guide was a young man, employee of a non-profit organization working with Sequoia National Park. He was hilarious and I enjoyed his talks and explanations about the cave.
We entered through a spider web-like gate and started a walk through the cave. I went through several rooms while taking many pictures particularly of stalagmites and stalactites, and the intricate designs on the wall made by running water. In the tour we stopped in 3 rooms and our tour guide introduced the room and pointed out several interesting places. In the first room we stopped at we saw many stalactites and our tour guide explained how the cave was formed and away we went walking deeper into the cave. At the second room which explorers named after musical instrument, Justin, my older brother correctly guessed that the musical instrument was a pipe organ on his 1st try. In the organ room we stayed and listened to his interesting explanation of the explorers who found this room, and how over long periods of time water formed this cave and pretty designs.
In the next and final room, also the largest room in Crystal Cave we turned off all the lights and imagined the animals which lived in the cave and how they survived and adapted in this dark cave. Then the lights came back on and we had a chance to examine the room. We all exited the cave and suddenly found that the tour was over. The tour had seemed to be so short. However I had a great time and really enjoyed the tour including the 15 minute scenic trail on the way back.
