The landscape is indeed very beautiful, but there are way too many people around. I walked in lines the whole day, making it very difficult to find my own pace. One can see that many of the visitors never go hiking, and that they were talked into a trip that is too long and strenuous for them. But don't worry, for any normal fit person it is a nice walk without any problems.
It is very recommendable to avoid the crowds and start very early in the morning, otherwise it gets really annoying.
