It is very long , I call it the Nile Valley of Tokyo , it's So Unique , right in the center of West Tokyo , I have never seen anything like it in my whole life , it has a forest of trees stretching from Ogikubo almost to Honancho in a series of vast parks interlaced with residential areas. I came across it by sheer accident back in 1999 , I couldn't believe my eyes , I had seen very few signs indicating that it even existed , I remember seeing a clump of woods in the distance and kept following the river to see where they ended but they never did , I just kept walking and walking for an hour , crossed Itsukaichi Dori and they kept on going , it seemed like no end in sight ! Finally I had to turn back. The next afternoon I started earlier and ended in Wadabori Park by the Big Pond and it still kept going. I had to turn back that afternoon and it took me another hour walking back! Finally the next day I took my Bike and arrived at Wadabori Pond , then it was a very isolated place , I discovered this small clump of houses in the middle of the park , People were living in them and were running this small open air restaurant called The River Side , it was like a little village in the middle of nowhere in this forest near the pond in The Middle Of Tokyo !!! What a Spectacle ! Unbelievable ! They were Friendlier than most people in Tokyo , very isolated and Country like. Near the pond I found this Circular Tent and met a man living next to the pond . I just could not believe my eyes ! About 5 years later a parking lot was built and the place was like any other park and more people came ! But before it was like walking in the Wilderness. One Day with my bike I finally rode my bike to the end almost to Honancho and in so doing discovered another very isolated wooded area. A park of Great Surprises And Adventure!
