I led a series of hikes in 2011-2012 for the AMC spanning the entirety of the North South Trail, a 77 mile footpath that begins at the RI/MA border and continues south to Charlestown and the Atlantic Ocean. It covers a variety of terrain from country back roads to deep pine forests, and was an excellent way to get outside close to home and see some parts of my home state I never knew existed. One thing I did struggle with was getting good information about the trail, maps, and info on where to start and end my section hikes. I decided to compile a map and create GPS/GPX tracks for each segment.
You can download the GPX files from my hikes; but know not all the tracks are entirely on the NST – I did some loop in segments 1 and for parking concerns sometimes we used feeder trails.
I take my GPS unit on all my hikes, for secondary navigation (always have a map/compass), but also to record my travels.
