From the South: Head north on Route 1 to Bath, once you cross over the Kennebec via the Bath Bridge turn right down 127/Arrowsic Rd. Drive for about 4.7 miles you will come to a bridge park on the right hand side. There is a pull off hear where you can park and change. Walk down the hill under the bridge and you will see the small island where the eddy line begins to form.
