Go to karioko village and when you pass the gates you will see a tree, take ten paces from that tree you should be in a wide,clear part of the area (note:if you have the stone of agony it should rumble) place a bomb over it and a hole should appear. there willbe a treasure chest and a golden rupee will be inside NOTE:you can only find the golden rupee in that treasure chest once it will not reapear. lol :p
