This popular trail near the intersection of Main Street (Route 9) and Quaker Hill Road features access to Sandy Stream, rich spring flowers, and an old Mill Site. There is poison ivy along the trail in places. A new seasonal crossing was installed over Bacon Brook in August 2016 with financial support from the LL Bean Maine Land Trust Grant Program administered by Maine Coast Heritage Trust.
Connor Mill Trail was first created by the CommUnity Trails group hosted by Unity Barn Raisers. Since 2009 it has been forever conserved by trail easements granted to the SRLT by Don & Pat Newell and Arlene & Charlie Schaefer.
