Literally "Child of God Pond", this is a small pond in the middle of the forest, reachable only by a long dirt track (no 4WD needed). What makes the bumpy trip worthwhile is that the water in the pond is a truly unearthly shade of transparent sapphire blue. The track is a few kilometers north of the
Ura-Mashuko (#3) lookout.
