The Allagash Wilderness Waterway is a 92-mile corridor of lakes, ponds, rivers and streams in northern Maine, usually paddled in seven to ten days from Chamberlain Bridge north to Allagash village. It runs from the Telos and Chamberlain lakes through Churchill Dam and Chase Rapids, down a chain of lakes and river miles to the St. John.
It is the most classic trip on this list — the one people's fathers did — and it earns its place here on isolation, cold water, big-lake wind and the logistics around Chase Rapids rather than on technical difficulty.
Registration instead of a lottery
Overnight campers register and pay per-person, per-night fees at North Maine Woods checkpoints or with Allagash Wilderness Waterway rangers. There is no advance lottery, but you have to pass a checkpoint to reach the put-ins, and that is where the fees are collected. Rangers register every party at the southern access and again at Michaud Farm near the north end.
Getting to those checkpoints is its own hazard: the access is by rough logging roads that routinely damage vehicles. Budget time and tires.
Chase Rapids, Allagash Falls, and the wind between them
Chase Rapids is Class II whitewater immediately below Churchill Dam, and it is the single piece of moving water most parties plan around. The Allagash Falls portage is mandatory — scout the take-out landing well above the lip rather than drifting down to find it.
Between those two points the recurring problem is wind on the big lakes. Chamberlain and Eagle can pin paddlers ashore for hours, which is why a 92-mile corridor takes seven to ten days rather than five. Cold water in spring and fall makes those crossings consequential, and black flies and mosquitoes peak through mid-June.
Seasons and water
May to mid-June brings high water that moves you along, and the bugs that come with it. Late June through August is peak season with stable water and warm days. September is cool, bug-free and colorful, though water runs low by late in the month. October through April the corridor belongs to snowmobiles and ice anglers.
Filter or treat all natural water. Potable water is occasionally available at ranger stations such as Churchill Dam, but that is a bonus, not a plan.
Full waterway, river half, or lake half
The full traverse is about eight days, Chamberlain Bridge to Allagash village. The river half — Churchill Dam to Allagash village, roughly five days — gives you Chase Rapids, Umsaskis and Long lakes and the Allagash Falls portage without the big-lake crossings.
The lake half runs the other way: six days from Chamberlain Bridge across Chamberlain and Eagle to Churchill Dam, for parties who want the open water and not the river. Moose are as dense here as anywhere in the East, black bears and bald eagles are common, and the cold tributaries hold native brook trout.
The most approachable trip on this list and still a real northern expedition — pick the river half for a first Allagash, and give the lakes their extra day.
