I've been all over and frankly the Carpathians are beautiful all around, however there are some no go zones because of mass tourism and human beings just shitting up the place.
Bușteni, Sinaia and Predeal. I'd avoid it if possible, a far better alternative on the area is Piatra Craiului, the Sfinx just isn't worth the hassle.
Other places to avoid: Roșia Montană, Cluj Napoca and Bacău.
My personal recommendations are Retezat and Moldoveanul (if you are alright with seeing 100 people on trail)
