So my wife and I went for a hike out to Wallace Falls State Park. I had a lot of fun! 
Granted, the hike started out okay, but when we arrived at the lower falls viewpoint, we realized how out of shape we both are. 
We had a choice of two hiking trails, the Woody Trail and the Railroad Grade Trail. The Woody trail was only 1.8 (2.9 Km) miles long, but the change in elevation is 450 ft (137m). In the end, the falls were beautiful and well worth the hike and the blisters.
Here are pictures of the falls.
