The saving grace of counties in Indiana beginning with H. Chock full of natural areas, rivers, caves, trails, etc. Home of Indiana's original state capitol, Corydon, which is worth a visit if you're interested in Indiana history. The Adventure Trail of Harrison-Crawford State Forest is here; you can make a good three or more day hike out of it. The Blue River forms the boundary between Harrison and Crawford Counties.
