Tsukui (津久井), Kanagawa Prefecture, Japan
You know that you went too far when you road turns into something like this. There is a very impressive scenic road starting from the border of Tokyo, and going alongside the cliff upwards Tsukui lake. The first part is a big road with a few traffic, the second a narrow and impressive path above the lake, and the third part has been totally destroyed by nature. I already tried to cross it once, went back, and convinced myself to make the full way to the end on today’s training.
