I know it seems to be very close to the Seven-trough springs, only a few air meters , but appearances can be deceptive. There is a 175m elevation difference between the two!
When you get to the top of the hill, bed down the horses in the stable, check the view, then you can go for the treasure about 100m from the monument.
There is a picnic place about 20m from the cache.
You'll probably find a throw away camera in the cache, please don't take it with you, instead take your picture with it!
