I was born in Krosno, about 70km south of Rzeszow. Can't tell you much about Rzeszow, but I would highly recommend a short trip to Krosno and possibly little deeper into Bieszczady. Krosno (many consider it a Krakow Jr) is a quaint town with many historical buldings, some of the oldest churches in Poland. Krosno site: http://www.krosno24.pl/miasto.php. It's only in Polish, but this page has a great aerial shot of the beautiful old town.

Go to this page and click rhe links in the middle of the page. Great pics of some of the old churches, old town, and other historical buildings.

Krosno is also a gateway for the Bieszczady region. Beautiful mountainous area with rich forests and a beautiful lake Solinski. The lake wa created when the biggest water dam in Poland was build back in the 60s. It offers many activities. Canoeing, bicycling, swimming, hiking, etc.. The following is a nice site for the region, but unfortunately it's in Polish only. This page has some great pictures of the area: http://www.bieszczady.pl/portal/html...trona=galeria1

Just few kms outside of Krosno is a Iwonicz Zdroj. It is well known all across the country as a popular health resort famous for its mineral waters and intact environment. Here is a great site in English: http://www.iwonicz-zdroj.pl/index_an.html

Have a great trip!
