There is a cute little park in Glenshaw, PA called Fall Run Park. We happened upon it because there are a couple geocaches hidden there. It's easy to get to, right off the beaten path. The trail winds about 3/4 deep into the revine. There is a lovely waterfall and several wooden bridges. We only found one of the two geogaches. The one near the falls called "Starwars" is what we were after, but alas it eluded us. Grrrr! Oh well... perhaps we will return another day.
