## Route

There are two ways to ascend Mount Ibuki. The easiest way is to use the Ibuki Driveway. The summit is a 10-minute walk from the parking lot. There is also a bus going from Sekigahara Station up to the parking lot in the summer months. The alternative method is to simply climb the mountain from its base. Many climbers climb from the Ibuki-Tozanguchi bus stop, which is 10 minutes by bus from Omi-Nagaoka Station on the Tōkaidō Main Line. Until 2011 there was a gondola going to the ski resort Sangome about halfway on the mountain slope. Both have been shut down since then and all the lifts have been removed.
