The staff was friendly & informative. The cave & underground lake were definitely worth the trip. Be prepared to hike a little up & down through out the cave.

The temperature in the cave is a constant 58 degrees although this is a fairly warm 58 degrees because the humidity in the cave is very high making the temperature seem a little warmer than 58. We hope to see you soon.
