The Hakone Ropeway runs between Soun Station in Gora and Togendai Station on the shores of Lake Ashi with Owakudani located between the two stations.
The most popular way is on the “Hakone Golden Route” which will take you up the mountain on the Hakone Tozan Train line to Gora Station. At Gora Station you will change to the cable car which will take you up the mountain to Soun Station. From Soun Station the cable car will take you directly to Owakudani and the steaming vents.

Some people find taking the opposite route a good way to get around the traffic. Taking the bus up to Lake Ashi from Hakone Yumoto, the boat across the lake to to Togendai, and the ropeway up to Owakudani.
