this a great run around a man-made lake in beautiful bucks county. there is a 1/4 mile 12% grade that is a great hill climb. there is also the dam area that i run up after a loop it is located in peace valley park, and it really is. all paved trail @ 8 ft wide min, all encompassing the lake, which has boat rentals,picnickers, bird watches, etc. firly even in ratio of walkers/runners, most know proper rules of the road, great in all seasons to run, use this in my marathon distance training. you can go either way for a break when doing your 20+ milers. safe,plenty of parking rest rooms,johnnies in winter time, only 1 1/2 miles on street, little traffic, plenty of offshoots for trailers too.
