Lowell, Massachusetts
Lowell National Historical Park
Nearly six miles of hand-dug canals, locks and gatehouses threaded through a mill city — proof the game works as well on a sidewalk as it does in the woods.
Researched from this park's own sources. Nobody's walked it yet.
Read this bit out
Before there were machines to do it, people dug nearly six miles of canals through this city with shovels, to take the power out of the river and use it to run the mills. Almost all of them still work. The water we see moving today is doing the same job it did two hundred years ago.
One of your three free places, or the Explorer Pass. What that costs
Before you go
- Time there
- Plan on about 2 hours at the park.
- Parking
- No entrance fee, but parking is paid: the closest is the Joseph Downes garage at 75 John Street, a block from the Boott Cotton Mills. The Hamilton Canal garage is the only free option and is a 0.6 mile walk. The lots signed "Resident Parking" at the Boott Mills are not for visitors.
- Underfoot
- City sidewalks and canal walkways the whole way — flat, paved, and the reason this pack exists.
- Stroller
- A stroller is fine here.
