text: A mile or so long trail along the Mon that goes from no place to nowhere via nothing It is a railstotrails conversion and it runs along a roadbed once used for shuttling coal between the rail line and barges Its parking lot on the eastern end was once a transfer point between the river and the slag dumps on Nine Mile Run The trail ends abruptly on the western end at the CSX Railway Some people trespass along the rail line with their bikes Do not do this because this is a very heavily used freight rail line It is also illegal and my husband the train enthusiast has said the train crews will radio the police to report tresspassersnnA couple of interesting points too This trail is is a paper street long owned by the city but never developed before The community of Duck Hollow is very isolated from the rest of the city and if you go just a little bit east of the trailhead along Old Browns Hill Road you will cross a one lane bridge and at the intersection of Old Browns Hill Road and McFarren Street I believe you will see one of the old Pittsburgh street signsnnDuck Hollow Trail is a pleasant trail but there is not much to it Eventually it may link with other trails as part of the Great Allegheny Passage I went on this trail once and even though I live nearby in Squirrel Hill I did not think it was worth the effort
