Erie Canal Lock 17 in Little Falls, New York is one of the highest lift locks in the world. When it opened in 1918 as part of the upgraded Erie Barge Canal, it was the highest single-lift lock anywhere — a 40.5-foot drop in a single chamber, replacing three smaller locks the older canal had used at this spot. More than a century later, it’s still in active commercial operation and remains one of the most striking pieces of canal engineering anywhere on the system.
For visitors to Little Falls, Lock 17 is a 5-minute drive (or a 20-minute walk) from downtown Canal Place, sits next to Moss Island, and pairs naturally with antiquing, dining, and a stop at Beardslee Castle. This guide covers what makes the lock worth seeing, how to visit, and where to stay nearby.
What Makes Lock 17 Worth a Visit
The lift itself. Most Erie Canal locks raise or lower boats 6 to 15 feet. Lock 17 moves them 40.5 feet — taller than a four-story building. Watching a barge or cabin cruiser drop or rise that distance in roughly 10 minutes is a genuine spectacle, especially up close from the viewing area.
The unusual gate design. Most canal locks use miter gates that swing open like double doors. Lock 17 uses a vertical-lift guillotine gate at the downstream end — a massive steel slab that rises straight up out of the water to release boats. This was a 1918 engineering solution to the unusually large lift, and Lock 17 is one of very few canal locks anywhere that uses this design.
The setting. The lock is wedged between the limestone walls of the Mohawk River gorge, surrounded by the rapids and potholes of Moss Island. The view from the lock viewing area takes in active commercial canal traffic in the foreground and ancient glacier-carved geology in the background.
Visiting Lock 17
Location and Access
Lock 17 sits at the southeast edge of Little Falls, on the south side of the Mohawk River. The most direct access is from Moss Island — drive across the iron bridge from downtown Little Falls (off South Ann Street), park in the small Moss Island lot, and walk to the lock viewing area. There’s a parking area at the lock itself off Mill Street for visitors who prefer to drive directly.
When to Visit
The Erie Canal navigation season runs roughly May 15 through October 15, and that’s the only time you’ll see boats locking through. Mid-summer afternoons (June through August) are the busiest for cabin cruisers, sailboats moving between the Great Lakes and the Hudson, and the occasional commercial barge. If you want to time your visit to actually see a lock-through, the New York State Canal Corporation publishes daily traffic counts at boating.canals.ny.gov.
What You’ll See
From the viewing area you can watch the entire 10-to-15-minute locking process: boats entering the chamber, the giant guillotine gate dropping behind them, water draining (or filling, depending on direction), and the gate raising again to release them. The lockmaster’s station is visible from the viewing area and the operation is largely automated, controlled from a central canal corporation facility.
Pairing Lock 17 with Other Little Falls Attractions
Lock 17 makes for a 30-to-45-minute stop on a Little Falls visit. Most people pair it with:
- Moss Island: Directly adjacent. The glacier-carved potholes and limestone climbing routes are a short walk from the lock viewing area.
- Canal Place antiquing: Little Falls Antique Center, Showcase Antiques, and the rest of the Canal Place district are a 5-minute drive back across the river.
- Beardslee Castle dinner: A 15-minute drive east. The historic stone restaurant is open Wednesday through Sunday for dinner.
- Erie Canalway Trail: The trail passes right over Lock 17. Cyclists and walkers using the trail get the best Lock 17 views.

Frequently Asked Questions
How tall is Erie Canal Lock 17?
The vertical lift is 40.5 feet, making it the highest single-lift lock on the Erie Canal system and one of the highest in the world. It replaced three smaller locks at this spot when the canal was upgraded between 1915 and 1918.
Can you visit Lock 17 year-round?
The lock is visible from the viewing area year-round, but active boat traffic only happens during navigation season, roughly May 15 to October 15. Winter visits give you the engineering and the setting without the lock-through spectacle.
Is there a fee to visit Lock 17?
No. Lock 17 is part of the New York State Canal system and is free to visit. Parking is free at the Moss Island lot and at the Mill Street lot near the lock.
How long does it take to watch a boat lock through?
A typical lock-through cycle takes 10 to 15 minutes from entry to exit. If you arrive when boats are queued, you may see several cycles in an hour.
What is Lock 17’s guillotine gate?
Most canal locks use miter gates that swing open like double doors. Lock 17 uses a vertical-lift guillotine gate at its downstream end — a massive steel slab that rises straight up to release boats. The unusual design was a 1918 engineering response to the unusually large 40.5-foot lift.
