Started from Enzan station (塩山駅) by bus at 8.30 AM and arrived at  Nishizawakeikoku-iriguchi (西沢渓谷入口) at 9.30 AM. One of the hottest and humid trail ever, sweated a lot, trail mostly in the bush but I was able to see Fuji san. Run a bit to catch the return bus at 3.40 PM from Nishizawakeikoku-iriguchi to Enzan station.
