There aren't a lot of trails, we were there maybe an hour or so. You can learn a little more here: http://jdcf.org/properties/horseshoe-mound/ One loop, though, is on a steep hill and takes some time.
The trails we took up there are not long . They do come out to overlooks bring your camera. They are not fancy but cool because there are structures that show true South..etc.
Mike pretty much covered it all.
