First to Sanok. If you come by train. Then passing Ustrzyki Dolne and Lutowiska to Zatwarnica (last stop).
From here you go by foot a little back then you turn left the way to the church, follow the way over the mountain, 100m before the bridge you turn right and after the ruins of an orthodox church turn left - and here you're in Hulskie!
(From Zatwarnica ca. 4 km by foot)
Here you find a map of South-East-Poland and a detailed map of the San-Valley.
