Roadside parking. Not an official boat launch, but it’s possible to walk beside the guardrail down to the water on the north west side of the bridge. From there, you can head left towards Sutton. The map shows an exit spot. You’ll see the picnic tables. Exit there and if you walk along High Street to the left, you’ll find Moolicious ice cream at the old mill building just past the bridge....or the Black River coffee house along the way.
Head right, and the river winds along in many directions.
