I think it's quite different from when I went. Even from 2013 to 2017, areas had been trampled: the moss that is so amazing was pretty much dead from photographers (there was one high profile gal with red hair who photographed herself lying on the moss, not realizing that she was tearing it up by the roots & would take years, if not decades to recover), as well as tourists who rented vehicles & drove off of the designated roads, doing damage that would take 50 years to recover and others killed sheep & put them in the trunks of their rented vehicles (yes, really!). Fortunately, people were filming everything with their phones, so miscreants were identified. So, yes, go, but be decent human beings. End of rant.
