A remote North Woods river flowing 30 miles through the vast commercial timberlands of Penobscot County to the East Branch of the Penobscot. The Seboeis delivers continuous Class II–III whitewater through an uninhabited boreal forest landscape with wild brook trout in every pool. Access is via private logging roads — this is deep Maine backcountry, requiring self-sufficiency and a sense of adventure.
