Stay above ground at Longhorn Cavern State Park.
This Backbone has a serious case of scoliosis and the cache could be in anyone of the vertebrae. They have limited trail maps at the visitor center but the trails are in good shape and well marked. They only collect fees at this park if you take the tour of the cavern (recommended). The cache is a clear plastic 1/2 gallon jar with white screw top lid. The cavern has multiple entrances so we hope you don't accidentally find and fall into a new one.
