Read this bit out
Nearly two hundred years ago, workers dug almost six miles of canals through this city to take the power out of the river and use it to run the mills. Many of the diggers were Irish, and it was hard, backbreaking work. Almost all of those canals are still here and still working. Today some of the water spins generators that make electricity instead of turning looms.
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. The closest parking is the paid Joseph Downes garage, 75 John Street, a block from the Boott Cotton Mills Museum. The Hamilton Canal garage, 350 Dutton Street, is free if you pick up a voucher at the Boott museum while it is open; otherwise you pay. It is a 0.6-mile walk. Both garages have a 6'8" height limit. The Boott Mills lots signed "Resident Parking" are not for visitors.
- Underfoot
- City sidewalks and canal walkways, much of it brick, with curb cuts but some uneven ground. The Northern Canal Walkway along the Great River Wall is open only May 15 to October 15, 9 a.m. to 5 p.m., and only when the river is low.
- Stroller
- A stroller is fine here.
- Bathrooms
- There are bathrooms.
- Food
- No picnic facilities listed, but downtown Lowell around the park has restaurants of every kind, from Greek to Vietnamese to Cambodian.
