Meramec Caverns are located in Missouri and are filled with exciting adventures that could easily fill up your entire day. This cave is actually the largest cave in Missouri, and they offer more than your average walking tours. If you are in the mood for some excitement, take some time and go on one of there zipline tours, where you can zipline through the caves and see them from a whole other angle. Also, checkout there calendar of local events (http://www.americascave.com/calendar.php) since they often host a lot of church festivals and activities throughout the year. One cool thing you learn about down here is how the ancient wine table was formed completely underground. Also, before you leave you have to see the light show, which is full in one room of the cave. This is where they project tons of lights around the cave in patriotic colors of red, white, and blue. This exhibit opened after 9/11, and got so popular they have kept it open ever since.
