poland – How much have Eastern Bieszczady Mountains changed over the last 30 years?

I used to trek across the Eastern Bieszczady Mountains 30 years ago when visiting Poland. It was awesome.

I am planning to be back (this time with my teen children) and would like to understand how much they changed. I am not talking about nostalgia but rather about the availability of food/housing on the mountains, also on how much the tracks were made easier. Overall I am trying to understand how much change I can expect.

In other words, would the “me from the late ’80s” be surprised if time transported to today, somewhere between Wetlina and Ustrzyki Gorne?
