This is a UPB cache, which according to the creator of "UPB", carnigrewal, doesn't come easy. Hike along the trail, beginning at the ruins until you have to go up the cliff. There is quite a bushwhack to the cache so young kids, neither dogs, aren't recommended.
I would suggest following the trail all the way to the other end to see all the cool spots and views on this side of the river! Also hiking the trail why not grab the other cache and also the EarthCache?
Please cover up the cache and replace as found.
Watch for poison ivy!
