 Take Rt. 28 north from Herkimer, NY and go past the Herkimer Diamond KOA campgrounds on the right (and store on the left).  The Ace of Diamonds mine is just a little further on the left, but the entrance is difficult to see if you haven't ever been there.  Look for mine equipment up on a hill and then the turn in is a reverse Y.  You may miss it and then proceed to a safe place to turn around and head bcak to the Y junction.
