Really nice ponds with lotus flowers; nothing in bloom in the photo above, but there is another adjacent pond which was jaw-dropping. Just fantastic. There is a small parking lot nearby these ponds, very easy access.

A beautiful day out walking through the rural area of 薭田野 and hiking through the nearby mountains. There doesn't seem to be an official signpost for these rare fish, but our search may have been insufficiently exhaustive. In any case, there were plenty of areas where we imagined said fish would thrive; we didn't actually see any though.

This K200 signpost is located near the bridge just north of the big "Sanga Stadium" in Kameoka. We didn't spent much time looking for the fish mentioned, since we just stopped by briefly before starting a long hike, though they were selling fish-shaped souvenirs at a gift shop in the JR station nearby. One may notice that the text on this signpost is slightly different from the others; it is bold-faced.

You need to ask for permission in advance to go into the mountains to see the geological formations specified by this sign; we just enjoyed the beautiful temple/shrine in which the K200 signpost was located, namely 積善寺 and 桜天満宮.

I struggled with route planning for this one. We drove to 洛西散策の森, which has a nice big parking lot. We walked almost all of those forest trails before moving to aim for the K200 signpost. There are several ways to get to it, but what we did was walk along the south side of the big E9 expressway (there is a small paved road running parallel). Eventually you reach a fork in the road, going left leads into a cemetary, and going right leads into the woods. Go right. Follow the road to its end, which leads to a tunnel up in the hills. Pass through this tunnel, and descend to the 首塚大明神 shrine. It is just a short walk from this shrine into the nearby settlement, where the signpost is located. Quite an interesting, remote location.
