I visied Caveman Zipline at Meramec Caverns in 2013 with a friend because she had never ziplined and it was the nearest one I could find at the time. We did enjoy the zipline. It was fun. I would do it again with someone, but probable not pay for it again just for myself as once is enough for the cost.
It has been so long since I have been to Meramec Caverns that I am sure it was before 2002 when I started taking digital photos. It is not a favorite place of mine because it is too commercialized. I may have to go again just to add to this page, though, or find my analog camera photos. The State Park camping area is always so crowded that I avoid it too.
I do have fond memories of my teenage years canoeing the Meramec River putting in around this area. I went so many times with various youth groups that I had the river memorized. Now I realize there are cleaner rivers, so I have not canoed here in a very long time.
