If I want to hike to the top of the mountain, what are some advices?
There are two trails in the Sounkyo Valley, and one of them is to the Kurodake. There are three sections of the trails. In the first section, you will take ropeway to the 5th station. Round trip ticket cost 1850 yens and takes about 7 minute for a one way trip. You may stay around 20-30minutes to check out the scenery. Afterward, hop on a chairlift to the 7th station. Round trip ticket cost 600 yens and takes about 15 minute for a one way trip. You will see a observatory station once arrived. It will take another 90 minutes to climb all the way to the top of the mountain.
