Rainbow Caverns was eerie, but not in a spooky way. It was more like you were discovering something beautiful that was previously unknown. If you look at those color photos and listen to this music, you can imagine yourself riding the train through the various rooms and past the pools and channels of glowing color, very close to the train. There was a lot of noise made by the falling water, but the music was also clearly heard. The music in this clip is the actual music that played continuously in the Rainbow Caverns. Start this clip and listen to it as you go back up and look at the color photos above.
