Start from WeSPa Tsubakiyama, go down National Route 101 to the south toward Lake Juniko Station. Uphill continues for a while, but there are many rest spots to use for recovery. Then you arrive at "Souvenir Shop Kyororo." Park your bike and walk for about 10 minutes, then you will finally see Blue Pond. As its name suggests, its mysterious water looks like blue ink was poured into it. The water is very clear, and the deep blue color is inspiring. You can even see the beech trees which sank to the bottom. Even though Blue Lake is at the farthest back among the Juni lakes, it is worth visiting to take a look at the mysterious sight.
