Can anyone recommend a cheap hotel, hostel or pension in this area?

You might want to give the name of the town that the tunnels are near to make things easier for responders. Silesia is a large area.

They Third Reich ruins are near the towns of Gluszyca, Walim and Walbrzych. Thanks for the tip.

This town has a TI that books accommodation:

I would get a copy of the Rough Guide to Poland and other guide books to look for accommodation. This board doesn't have many posters who have been to Poland.

I googled Gluszyca and got a lot of hotels in the area. Hotels in Poland (outside of the major cities) will be quite cheap.

Thank you very much for your input.

once I was in a guest house Sowia Grapa it is in Rzeczka, very cole to the ruins. Prices are very ok and have big breakfasts.
Nice sighseeing ;-)
