I grew up in the Poconos, but I'm not really sure what the different areas offer in terms of buying homes. You don't mention where you live, which makes a big difference in the Poconos. The Poconos is a fairly large and spread out area.
Anyway, one of the most popular places where I grew up was Lake Wallenpaupack, but it was primarily owned by New York visitors. Another popular place was The Hideout near Hamlin. That is a gated community. If you are located closer to Philadelphia, then you'll probably be looking at the southern part of the Poconos. I knew some people that owned in the Jack Frost / Big Boulder area and liked it. Parents of a friend of mine had a chalet in that area that we visited, it was very nice.
