As you drive through Georgia, Alabama, Tennessee, and several other states you will pass signs advertising "Visit Ruby Falls." This I have done on at least 10 different occasions, usually when friends or family have come to visit. Most people that I know desire to see this wonder at least once, so I make sure that they have the opportunity.
The entrance of the cave can be obtained after taking the beautiful drive up historic Lookout Mountain. The views along the drive are very scenic, especially in the spring and autumn. My wife was pleased when she noticed that there are several antique stores that were passed. (She always enjoys stopping in the stores and looking at the antiques.) After a few miles (that seem to take hours to drive), you pull into the parking area and walk to the entry/gift shop to visit this natural wonder.
Tickets for a tour of the cave can be purchased for less than $10 per person. There is usually a short wait so that sufficient tickets for the tour can be sold, and then the tour group boards an elevator that whisks you down into the mountain to reach the cave level. The elevators open to allow access to the cave passage. Several quartz formations can be seen as the group heads toward the ultimate view on this trip. The tour guide takes the time to explain how several of these formations were formed.
Finally, as the group rounds a final corner, the lights are turned out. You can hear the roar of water cascading into the cave. The lights are relit; a torrent of water can be seen through the filtered lights. The red, blue, and green of the filters plays off of a 200 foot stream of water pouring from the roof of the cave into an opening in the floor. Visitors are given the opportunity to walk around and behind the falls. Eventually the group makes the return trip to the surface.
Each time that I visit this attraction I gain new insight into it. The first few visits bored me, but I have gained a greater admiration for this wonder of nature. This is a MUST SEE for every visitor who passes through the Chattanooga area.
