This is a pretty traditional cache, its located in the woods in the Hernitage of the Braid on public land, and is pretty easily accessible via the trails from car parks.
Its a reasonably small tupperware box, you'd probably not be able to fit a CD in but lots of other things will fit in. The cache is on a trail on the top right hand side of the Hermitage dale.Approach from the path to the east parking spot will be MUCH easier than midmar carpark
