For those looking for a full day trip, the Squanni is perfect. We started at the VFW in Townsend and ended near the H&V paper mill in Groton. This trip takes about 8-9 hours to complete (depending on how often you break). the great thing is if you feel like that is too long there are other places to launch/end.
From the VFW it took us about five hours to get to the harbor pond (a possible end point for those in search of a shorter trip). This is the one spot where we had to get out and walk the kayaks a short distance around the dam.
Although there are trees down here and there, it's a fun continuous paddle and the obstacles just make it even more of an adventure! I hope to discover new rivers in the area that are similar or even a bit faster than this one.
