Approach and accomodation:
In time of summer school holidays ( 26 June till 31 August ) in Poland approach from the various places of Poland is not a problem:
there are a lot of railway connections (to Zagórz, Sanok, Przemyśl ) and buses - e.g. the connection from Cracow to Ustrzyki Górne.
The approach is much more complicated after the season. If You don't have Your own car, the best way is to travel by train to Przemyśl or Rzeszów
from these cities are some buses to Ustrzyki Dolne, where we have to change bus following to Ustrzyki Górne ).
The hostel base is generally quite good. In villages: Wetlina and Ustrzyki Górne there are private guest-houses, some hostels and camping fields.
I used to stay on the camping field in Berehy Górne, but You have to know that there are'nt any facilities: bath in the stream, and you should go approx.
10 km to the closest shop in Ustrzyki Górne. Very nice place to stay is mountain-hostel ( bacówka ) "Pod Rawkami" being placed between two alpine tundra
(połonina) - Połonina Caryńska and Wielka i Mała Rawka.
