I gave a talk at the Annual
Westfield River Symposium last month and talked about trail opportunities in the lower watershed. See this website to download the trail guide
http://robertbristow.home.comcast.net/. It had been available on the river.wsc.ma.edu site but this site is no longer online, so I mirrored the data on my personal site for your hiking pleasure. It is raining right now, but since the temperatures are getting warmer, now is the time to get outside!
Enjoy.
