If you were to visit the Kamikochi and Kurobe Alpine Route on your own, you would need to do a lot of research and it would be quite inconvenient. With KKDAY's tour, we saved a lot of time on planning and didn't have to worry about many things. It was a worry-free, comfortable group tour. Our guide, Zheng Qiang, was very interesting and interactive, and he even took photos for us. He seemed to have a passion for photography, so his photos turned out quite well. The attractions are definitely worth visiting. The transportation, accommodation, and restaurant meals were all excellent. Overall, aside from having to get up early, there's nothing to complain about. Thumbs up!
The guide handled the tickets for all transportation, can not think about following is ok.Hopefully the guide is disbanding a little more explanation, there are a couple of points too much time and finally make the return time late, but overall a very convenient trip!
