A 75-mile Downeast Maine wilderness river flowing from the remote bogs and lakes of Washington County to Machias Bay on the Atlantic. The Machias is one of Maine's most important Atlantic salmon restoration rivers — federal and state agencies have invested heavily in removing dams and restoring habitat. Multi-day canoe trips through vast, uninhabited blueberry barrens and boreal forest define the Machias experience.
