If you like bird watching, I live near the largest Great Blue Heron Rookery in Pennsylvania. It is a sight to see when the young ones fledge.
The Delaware River has canals on both sides which are Rails to Trails paths. The PA Canal 65 miles long and is a great place for hiking and biking with lots of small towns along the way to find great food and shopping.
For history buffs, Washington Crossing State Park is just down the river along the canal and yes it is the place where the army crossed and headed to Trenton and Princeton.
The Crayola factory is up the river. Watch crayons being made and a fun place for little kids.
There is lots of camping grounds around my area.
Lots of 2nd hand shops and antiquing in many small towns.
I love the eastern edge of PA and call my home Camp lulu.
