I would have given it 5 stars, but driving up winding roads can get lightly irritating.
BUT! The scenery you see on this 30-40 minute drive is amaaaaazing. You are so high up and can see for a great distance. I went up this trail in autumn and the leaves were all red and gold. If you like nature and super pretty trees, put this trail on your list of things to do!
After you reach the top, you can visit other attractions like Lake Chuzenji and Kegon falls! so your day can be extra "fun filled" woo!
