Mitou Waterfall-Mt. Mitou-Mt. Nukazasu-floating bridge on Okutama Lake

I walked Mt. Mitou (三頭山), Mt. Nukazasu (ヌカザス山), Mt. Iyo (イヨ山) and floating bridge (浮橋) on Okutama Lake (奥多摩湖). First, I went to "Tokyoite's forest" in Okutama area so as to climb up to Mt. Mitou (三頭山).

Mitousan_trekking The main target of this trek was to see Mitou Waterfall (三頭大滝) and walk up Mt. Mitou and walk on a floating bridge on Okutama Lake.

A blue line shows my trekking route, a yellow one is a bus route. I walked about 11.1km for 5hr07min.
I guessed that if the weather will be fine, Mt. Fuji will be seen from the summit of the mountain. The Mitou waterfall had been covering with white thin moisture vapor. So, a view from the summit of Mitou Mountain was also hopeless. Moreover, the temperature was lower, and it had no wind.

Dscf0988s Walking down from the summit of the mountain to Okutama Lake takes about 1000m vertical distance. At the beginning of walking from the summit, I thought it is not so steep. After few minutes, the inclination of the mountain path became steep suddenly. By the rain by yesterday, the mountain path was slippy, I made my stride short, and I had to walk carefully. I thought that a shock of downhill walking will be given knee fatigue and injure. So, I walked softly to prevent a knee impact.

After you get down from a mountain, you have to walk on a paved road. The road does not have a pedestrian road. And, in a holiday, it will be a dangerous road because motor-cyclists will be driven as if it were a racing road.
Walk along the road to seeing a lake on your left. A water place will be found after few minutes walking. I wiped my body with cool spring water at that place and changed into a dry new shirt. Walk along the road about one minute, you will find a path to a floating bridge (浮橋). The direction board to a floating bridge is on a cut line of the guard rail.

Dscf1143s Dscf1153s If you were walking on the bridge, you will be felt to become a ninja who walks on the water surface. When you finish crossing a floating bridge, the bus stop to JR Okutama Station (奥多摩駅) going is located about 30m left from a tunnel mouth. The bus access to the station is difficult to use. Please check the time table prior to use.
The bus fee can use a SUICA card.

Tokyoite's forest is the natural park for Tokyoite. The height of the place is about 1000m but easy to access. We can go by bus from JR Musashi Itsukaichi (武蔵五日市) Station. There are many enjoyable spot. Mt. Mitou (三頭山), Mitou Waterfall (三頭大滝) and the other activities are in the park.

For the Family
I think that 大滝の路コース(A course to visit a waterfall) is good for all the family.
It takes about one hour walk.

The course is that

森林館 (forest house)-->大滝の路 (path to waterfall)-->三頭大滝 (Mitou waterfall)-->大滝の路 (return path from waterfall)-->森林館 (forest house)

The path is paving by wood chips that soften a shock of our steps.

If your child could walk a mountain path a little more, my 2nd recommendation is 三頭沢と野鳥の森コース (A course of mountain stream and wild bird).
It takes about 3 hours walk.
The course is that
森林館 (forest house)-->大滝の路 (path to waterfall)-->三頭大滝 (Mitou waterfall)-->野鳥観察小屋 (a house to observe wild birds)-->かおりの路-->森林館 (forest house)
If your child could climb on a low mountain, the 3rd recommendation is 生活の森コース(A course of a living in forest).
You and your child have to climb up to Shouguchi Peak (鞘口峠, H=1142m), the height difference that need to climb is about 140m.
It takes about 3 hours walk.
The course is that
森林館 (forest house)-->里山休憩小屋 (mountain shack)-->山菜の路 (path along a mountain vegetable field)-->里山の路 (paths around mountain village)-->鞘口峠(Shouguchi Peak)-->森林館 (forest house)
