One of the largest river basins on the East Coast, the St. John drains over 21,000 square miles of land. Its upper portions are some of the most remote stretches of river in all New England.
The French explorer Samuel de Champlain named the river after sailing into its mouth on the Nativity of St. John the Baptist day in 1604.
A tributary, the Allagash, is a favorite canoeing destination. To protect this remarkable river, the state of Maine created the Allagash Wilderness Waterway, a Federally-designated “Wild and Scenic River.”
