My son and I did the Old Logger's Path this past (hot) weekend in 1.5 days. It was hard. But we were going quick and it was very hot. GPS told us 15 hours hiking including breaks. Looking for our next trail before the boy heads to college. Thinking about Allegheny Front Trail or Black Forest Trail. We're looking for a 3-day kind of hike; maybe 4 days. Any recommendations? Thanks!
