About Allagash Falls

Allagash Falls is a 31-foot segmented in Maine, on Allagash River.

It's fullest after rain, and flow can drop off during dry spells — plan around recent weather.

Plungeworthy rates Allagash Falls 7/10 — worth the drive. The score weighs its scale, how confidently it's mapped, and its character.

What you'll find

Allagash Falls is the signature landmark of the Allagash Wilderness Waterway — a wide drop of 30 to 40 feet near the lower end of the 92-mile river system that most multi-day paddlers treat as the trip's highlight. A mandatory portage of about a third of a mile carries canoes and gear around the falls; running it is prohibited.

The falls sit inside true wilderness: no road reaches it, and getting there means committing to a multi-day canoe expedition through one of the last free-flowing wilderness river corridors in the eastern US.

This is the most remote, most effort-intensive waterfall in Maine by a wide margin — not a day-trip destination at all, but a genuine wilderness-trip payoff for paddlers already deep into the Allagash.

Getting there

Road: No road access — paddle-in only, via the Allagash River as part of an Allagash Wilderness Waterway canoe trip
Hike: 0.33 mi round trip (The only walking is the mandatory portage trail; the falls is otherwise reached entirely by canoe)
Heads up: Designated campsites at the falls; the portage trail runs along the riverbank.

When to go

Reached during the open-water paddling season, roughly late spring through early fall. A full waterway trip typically runs more than a week; shorter multi-day sections are common.

Before you go

The pin marks the feature, not a trailhead or a legal route in. Some sit on private land or need a real hike, and conditions change with season and rain. Check local access, don't trespass, and never enter water — hot or cold — where it isn't safe.
