Well, I guess if they just charge hikers who blatantly go by closed and no trespassing signs fir a photo op, I don't see a problem. Looking at the places mentioned by name, Sacred Falls, nice but like falls here, if you catch them when it's not rainy season or after a good rainfall, the flow probably is meager.
I can't believe they built Stairway to Heaven, Breathtaking yes, invasive to nature and way too narrow to really handle two way traffic. I can't believe they built it at all.
