The 5 mile CamRock Trail starts in the charming town of Cambridge and ends at the CamRock County Park. The 400+ acre park follows Koshkonong Creek, which eventually empties into Lake Koshkonong. There is a nice playground and the trails are well groomed and level. Perhaps not the most scintillating of hikes, but still shady and pleasant with glimpses of the creek.
Area 3, in Rockdale, does have a very pretty bridge and some trails that wind into the woods.
