Trask Brook and Paradise Roads are a one-mile continuous road that changes names from Sunapee to Newport. Enter from NH-103 in Wendell (Sunapee) near Sanctuary Dairy Farm, a great place for ice cream. The Newport end has a closed bridge. There is a bridge over Trask Brook which is a good place to park. Watch out for poison ivy; there is a lot of it here. It is good birding from this bridge most of the way to the closed bridge over the Sugar River.

Trask Brook Road goes north from NH-103 to Maple Avenue.
