Hakone Ropeway is a definite highlight of the region! You will enjoy breathtaking views of active sulfuric hot spring sources in the Owakudani Valley, glimpses of Lake Ashi and even view of Mt Fuji from the ropeway, especially between Owakudani Station and Ubako Station!
TIP - you can buy the ticket individually or as part of the Hakone free pass which is worth it if you're exploring all of Hakone and its attractions in one day!
