Allagash Wilderness Waterway

ByWilderness Experts

Fast facts

  • Established: 1966; a National Wild and Scenic River since 1970
  • Length: 92 miles (148 km) of lakes, ponds and river
  • Character: a protected corridor through the commercial forest of northern Maine
  • Gateway: Millinocket and the village of Allagash
  • Managed by: Maine Bureau of Parks and Lands

The landscape

The Allagash flows north through the North Woods from a chain of big lakes, including Chamberlain, Eagle and Churchill, down a winding river to the St. John near the Canadian border. Spruce-fir forest lines the banks, and the waterway passes logging history such as the abandoned locomotives at Eagle Lake. Moose, loons, bald eagles and brook trout are common.

Best time to go

Ice-out comes in May. June brings high water and blackflies; July and August bring warmer weather and lower water, with more rocks showing in the river. September is cool and beautiful, with fewer bugs.

Getting there and around

Put-ins are reached by long drives on gravel logging roads through North Maine Woods checkpoints, where fees are paid. Most paddlers start at Chamberlain Bridge or Churchill Dam and paddle north over a week or more, arranging a shuttle from the village of Allagash.

Things to do

The full waterway is a classic week-to-ten-day canoe trip, mixing big-lake crossings with river travel. Chase Rapids below Churchill Dam offers the main whitewater, and Allagash Falls requires a portage. Fishing, moose watching and historic sites fill the days.

Staying safe

Big lakes such as Chamberlain can build dangerous waves in wind; stay near shore and cross early. Scout Chase Rapids and portage Allagash Falls. Water is cold early in the season, and low water later can make the river slow and rocky. There is no cell service, so carry a satellite messenger and leave a trip plan. Drive logging roads carefully and yield to trucks.

Know before you go

Register at the checkpoints and camp only at designated sites. This page is a general overview, not a live conditions report, so confirm water levels and rules with the Maine Bureau of Parks and Lands before you go.
