How Long Is The Erie Canal? Miles, Locks And Cruise Distances Explained
Ask how long the Erie Canal is and you will get at least three honest answers: 338 miles, 363 miles, or 360.3 miles. Each number is correct for a different version of the waterway, and knowing which is which is the key to planning a cruise.
Short answer
The Erie Canal today is 338 miles long, running from Waterford on the Hudson River to Lake Erie, with 35 locks managing a 571-foot elevation change between Albany and Buffalo. The original 1825 canal was 363 miles with 83 locks. The Erie Canalway Trail beside it runs 360.3 miles from Buffalo to Albany.
The question sounds simple, and the honest answer comes in three numbers. The Erie Canal you can cruise today is 338 miles long, stretching from Waterford, where the canal meets the Hudson River, west to Lake Erie. The canal dug between 1817 and 1825 was 363 miles. And the Erie Canalway Trail, the walking and cycling route that shadows the waterway, runs 360.3 miles from Buffalo to Albany. All three figures appear in official sources, and mixing them up is the single most common error in canal coverage. If you'd rather explore the waterway without spending anything, our guide to free activities along the Erie Canal covers the trail, locks, and walking tours in detail.
The numbers matter for more than trivia. A traveler deciding between a 90-minute cruise in Pittsford and a two-hour cruise in Lockport is really asking how much of this famous waterway they will actually see, and the answer is a short, carefully chosen stretch rather than the whole corridor. This guide lays out every length figure in circulation, explains why the original canal and today's canal measure differently, and shows what a public cruise covers in practice.
How Long Is The Erie Canal Today?
The Erie Canal today runs 338 miles from Waterford, where it meets the Hudson River, to Lake Erie, and it carries 35 locks that lift or lower boats a total of 571 feet between Albany and Buffalo. The original 1825 canal was 363 miles long, took eight years to build, cost $7,143,789, and opened with 83 locks. Both canals connect the same two endpoints by very different routes. To understand how those two routes diverged and why the original ditch became the modern one, read our guide to the Erie Canal's building and legacy.
The 338-mile figure comes from the Erie Canalway National Heritage Corridor's own pages on the canal as it exists now, a channel 12 to 23 feet deep and 120 to 200 feet wide, with locks 310 feet long, built to handle modern commercial and recreational traffic. Construction started in 1817 in Rome, and the finished ditch opened in 1825 with an event organizers called the Wedding of the Waters, in which a keg of Lake Erie water was poured into the Atlantic. The heritage corridor's canal today page is the cleanest single source for the modern mileage.
The elevation number deserves its own sentence. Between Albany and Buffalo the canal climbs and falls a combined 571 feet, which is why the locks exist at all: a flat boat cannot cross New York State without help. The corridor's fast-facts page lists the 571-foot figure alongside the original canal's dimensions, and the two sets of numbers make a useful comparison.

Here are the core length and lock figures in one place.
| Measurement | Value |
|---|---|
| Erie Canal length today | 338 miles, Waterford to Lake Erie |
| Original canal length, 1825 | 363 miles |
| Locks on the Erie Canal today | 35 |
| Locks on the original canal, 1825 | 83 |
| Locks on the full NYS Canal System | 57 |
| Elevation change, Albany to Buffalo | 571 feet |
Why Do The Original And Modern Canals Have Different Lengths?
The Erie Canal you can cruise today is not the ditch dug between 1817 and 1825. The original waterway ran 363 miles with 83 locks, each 90 feet long, in a channel 40 feet wide and 4 feet deep. Today's canal runs 338 miles with 35 locks, each 310 feet long, in a channel 120 to 200 feet wide and 12 to 23 feet deep. Fewer, bigger locks let a shorter route carry far larger boats.
The shortening is not a surveying error. Successive rebuilds straightened the route and replaced the original 90-foot locks with structures 310 feet long, so a lock that once lifted a small packet boat now handles vessels more than three times that length. Dropping from 83 locks to 35 reflects that consolidation: each modern lock does the work of several original ones. The depth change is the most dramatic of all. Four feet of water was enough for the flat-bottomed packet boats of the original canal, while today's channel needs 12 to 23 feet for the traffic it carries.
For a visitor, the practical difference is scale. The original canal was a narrow, hand-dug trench where mules walked the towpath; the modern canal is a managed waterway with substantial river sections, wide prisms and industrial-size machinery at every lock. When a tour guide on a cruise boat talks about "the original canal," they are usually pointing at a surviving fragment of the 40-foot channel, often visible beside the modern waterway, while the boat itself floats in the enlarged version. The Erie Canal locks explained guide covers how those machines work, and it pairs well with the length figures above.
The original-versus-today comparison is easiest to read side by side.
| Feature | Original Canal, 1825 | Canal Today |
|---|---|---|
| Length | 363 miles | 338 miles |
| Locks | 83 | 35 |
| Lock length | 90 feet | 310 feet |
| Channel depth | 4 feet | 12 to 23 feet |
| Channel width | 40 feet | 120 to 200 feet |
If seeing locks in action is the goal, three cruises on this site's roster deliver it in different settings.
The Lockport cruise is the featured option for a reason: it passes Locks 34 and 35, the double set the operator describes as the only one of its kind on the Erie Canal, in about two hours on the water. The Herkimer cruise runs 90 minutes through Lock 18 in the Mohawk Valley, and the Pittsford cruise from Sam Patch Dock passes Lock 32 on its 90-minute run. Each one shows a working lock from the water, which is the best classroom for understanding how the canal's 571 feet of elevation change is actually managed.
How Much Of The Canal Does A Cruise Actually Cover?
A public cruise covers a short stretch, not the whole waterway. The longest cruise on this roster is Colonial Belle's 3-hour lock cruise from Fairport; the standard sightseeing run is 90 minutes, the length of the Herkimer and Pittsford boats. A two-hour Lockport cruise passes the double lock set at Locks 34 and 35 and returns to the dock.
The honest framing is that no public cruise on this site comes close to the canal's full 338 miles, and none needs to. A cruise is a window, not a traversal: the boat leaves a dock, works a scenic or historic stretch, sometimes passes through a lock, and returns. The Lockport operation, sailing from the Flight of Five at 210 Market Street, turns the biggest single climb on the canal into a two-hour loop. The Herkimer boat, the Lil' Diamond II, works Lock 18 at Jacksonburg from a dock at Gems Along the Mohawk. Colonial Belle, a boat launched in 1961 that celebrated its 65th launch day in June 2026, offers the longest public rides on the roster from Packett's Landing in Fairport, including a 3-hour version that passes through a lock.

Here is what each cruise length buys, using the durations and from-prices on each listing.
| Cruise | Departure Point | Duration | Lock Passage | From Price Per Adult |
|---|---|---|---|---|
| Lockport Locks & Erie Canal Cruises | Flight of Five, Lockport | About 2 hours | Locks 34 and 35 | $26 |
| Erie Canal Cruises, Herkimer | Gems Along the Mohawk, Herkimer | 90 minutes | Lock 18 | $29 |
| Rochester By Water, Sam Patch | Sam Patch Dock, Pittsford | 90 minutes | Lock 32 | $30 |
| Colonial Belle afternoon cruise | Packett's Landing, Fairport | 2 hours | No lock | $36 |
| Colonial Belle lock cruise | Packett's Landing, Fairport | 3 hours | Through a lock | $44 |
| Colonial Belle evening lock cruise | Packett's Landing, Fairport | 3 hours | Through a lock | $46 |
The pattern is clear: duration and lock passage drive the price more than scenery does. A 90-minute cruise from a village dock runs $29 to $30, a two-hour cruise with a double lock set starts at $26, and the three-hour Fairport lock cruises start at $44 to $46. The Erie Canal cruise prices guide breaks these down further, including child, senior and military rates on each listing.
Colonial Belle's 3-hour lock cruise is the longest public ride among the Fairport options, and its rating of 4.2 comes from a thin sample of 53 reviews, so treat it as a promising signal rather than a verdict. Its 2-hour afternoon cruise skips the lock entirely, which makes the 3-hour version the choice for travelers who specifically want the lock experience from Fairport.
For travelers who want more than a window on the water, there is a middle path between a 90-minute cruise and owning a boat: renting one. The Erie Canal boat rental guide covers that option in full, but the short version is that self-skippered canal boats from Macedon let a small group cover real distance over several days, with the operator providing orientation and training before departure.
Canal, Trail Or System: Which Length Are You Being Quoted?
Three different lengths get quoted for the same corridor. The Erie Canal itself is 338 miles, Waterford to Lake Erie. The Erie Canalway Trail beside it runs 360.3 miles from Buffalo to Albany, inside a 423.7-mile trail network that is part of the 750-mile Empire State Trail. The New York State Canal System, all four canals together, carries 57 locks, of which the Erie Canal accounts for 35.
The trail figure is the one that causes the most confusion, because the Erie Canalway Trail does not follow the waterway's route exactly. It runs 360.3 miles from Buffalo to Albany, a few miles longer than the canal itself, and it sits within a 423.7-mile network of canal-side paths. The whole system is a segment of the 750-mile Empire State Trail, the state's coast-to-coast walking and cycling route. So a cyclist who says they "did the Erie Canal" may mean 360.3 miles of trail, while a boater means 338 miles of water, and both are correct. The Canal Corporation's trails page carries the official mileage.
The lock count splits the same way. The Erie Canal has 35 locks, but the New York State Canal System, which adds the Champlain, Cayuga-Seneca and Oswego canals, has 57 in total. A statistic like "57 locks" in a news story refers to the whole system, not the Erie Canal alone. The Erie Canalway Trail and bike guide untangles the trail network in more depth, including current closures that matter to anyone planning to ride it.
How Long Does It Take To Travel The Canal By Boat?
There is no single crossing time: it depends on boat speed, lock waits and lock hours. Locks on the system operate 8 a.m. to 6 p.m. daily, with extended 8 a.m. to 9 p.m. hours at select locks in peak season, so private boaters plan each day around them. The Canal Corporation tells boaters to arrive at the Waterford Flight by 5 p.m. to make the full flight.
The lock hours are the real constraint on any end-to-end trip, because a boat cannot be lifted through a closed lock. The extended peak-season hours include Lock E-34/35 at Lockport, Lock E-32 at Pittsford and the Fairport lift bridge, which matters for anyone timing a cruise-day arrival around those spots. The how long does it take to cruise the Erie Canal post works through crossing scenarios in detail, and the short answer is that a full Waterford-to-Lake-Erie transit is a multi-day commitment shaped by the 6 p.m. lock cutoff, not a single long day.
For cruise passengers the question is simpler, since the operator handles all of it. A 90-minute cruise spends its time inside one lock at most, and the boat returns to the same dock it left. The one scheduling habit worth adopting is checking the operator's page before driving out, because departure times shift with the season: Lockport adds a 10 a.m. sailing daily from June 23 to September 6, and Herkimer's schedule varies between 1 p.m., 3 p.m. and some 10:30 a.m. departures across its May 22 to October 12 window.

Lunch-length cruises split the difference between the quick run and the long ride. The Sam Patch operation at Pittsford sells a Lock 32 cruise with lunch added, at $53 per adult, a $30 cruise ticket plus a $23 lunch, which turns a 90-minute lock passage into a meal-length outing on the water.
The rental route changes the arithmetic entirely. Erie Canal Adventures, the Macedon-based operator that is the former Mid-Lakes Navigation under a name adopted in 2019, charters self-skippered Lockmaster boats by the night, from $2,770 per private boat for a 3-night charter, with fuel, tolls, orientation, training, linen and equipment included. A 3-night charter is still a fraction of the canal's 338 miles, but it covers enough distance to sleep aboard and wake up somewhere new.
Where The 571 Feet Happens: Lockport And The Locks
The 35 Erie Canal locks manage a 571-foot elevation change between Albany and Buffalo, and the steepest single step is at Lockport, where Lock E-35 lifts 24.6 feet and Lock E-34 lifts 24.5 feet for a combined 49.1 feet. The Lockport tour operator rounds this to 50 feet in its marketing; the official guidebook figure is 49.1 feet.
That double step is why Lockport is the most dramatic place on the canal to watch locks work. The Niagara Escarpment, the limestone ledge that the canal had to climb, stands about 60 feet high at Lockport, and the original Flight of Five locks handled the rise in five stages. Two of those 1849 locks, numbered 69 and 70, were restored and reopened in 2014, and they sit beside the two modern locks that do the work today. A cruise passenger at Lockport watches the boat rise the equivalent of a five-story building in two lockages, with the restored stone locks visible alongside. Those restored stone chambers are living proof of the canal's survival, and if you want to see how much of the original waterway still carries boats today, the surviving stretches of the Erie Canal map them out.
The Lockport Locks & Erie Canal Cruises operation, sailing from the Flight of Five at 210 Market Street, is the featured cruise on this site precisely because of that terrain. Its listing carries a Tripadvisor-scope rating of 4.8 across 865 reviews, one of the two deepest review pools on the roster, and its 2026 public season runs May 11 to October 16 with daily 12:30 and 3 p.m. sailings. You can read the full Lockport Locks cruise overview on its tour page, or go straight to Check availability on the operator's live listing.

The rest of the 571 feet is distributed along the route in smaller steps, which is why most locks elsewhere feel routine rather than theatrical. The where is the best place to see the Erie Canal locks post ranks the viewing spots, and the which cruises go through a lock guide lists every lock-passing cruise on this roster, including the no-lock options to avoid if a lockage is the whole point of the trip.
When The Canal Is Open: Season Length Versus Cruise Length
The 2026 navigation season runs Friday, May 15 through Wednesday, October 14, the 202nd consecutive year of operation, and there are no tolls or fees for recreational use. Cruise operators keep their own windows inside that span: Lockport sails May 11 to October 16, Herkimer May 22 to October 12, and Colonial Belle from Fairport May 15 to October 30.
The distinction between the canal's season and each operator's season trips up a lot of planners. The Canal Corporation opens and closes the waterway itself, and outside that window the locks stop operating, which ends most boating. But tour boats set their own calendars inside, before and around it. Colonial Belle's Fairport season extends past the canal's closing date to October 30, and Lockport starts before the official opening on May 11, because their cruises work a short stretch whose locks they can schedule around. The Canal Corporation's boating hours page is the authority on the waterway's own dates.

Practical advice follows from the calendar. Early May and mid-October are shoulder edges where only some operators are sailing; mid-June through Labor Day has the widest choice and the most departures, including Lockport's extra 10 a.m. slot. Weather and water levels can still change any sailing, so the standing recommendation is to check the operator's page close to your date. The best time for an Erie Canal boat tour guide works through the whole season month by month.
Whatever stretch of the 338 miles you choose, the practical decision comes down to which dock, which lock and how many hours on the water. This site, Erie Canal Boat Tours, compares every cruise and rental on the canal side by side, and the trio below covers the three most useful starting points: the double locks at Lockport, the Mohawk Valley's Lock 18, and the Pittsford run through Lock 32.
Common Questions About The Erie Canal's Length
How long is the Erie Canal?
The Erie Canal today is 338 miles long, running from Waterford on the Hudson River to Lake Erie. The original 1825 canal was 363 miles. The Erie Canalway Trail beside it runs 360.3 miles from Buffalo to Albany.
How many locks does the Erie Canal have?
The Erie Canal has 35 locks. The full New York State Canal System, which also includes the Champlain, Cayuga-Seneca and Oswego canals, has 57 locks in total.
Why was the original canal longer than today's canal?
The original 1825 canal followed a hand-dug 363-mile route with 83 small locks, each 90 feet long. Rebuilds straightened the route and replaced the small locks with 310-foot structures, cutting the distance to 338 miles while allowing much larger boats.
How much elevation does the Erie Canal cover?
Boats on the canal climb and fall a combined 571 feet between Albany and Buffalo. The steepest single step is at Lockport, where two locks lift boats a combined 49.1 feet up the Niagara Escarpment.
Can you cruise the entire Erie Canal?
Not on a public sightseeing cruise. The cruises on this roster run 90 minutes to 3 hours and cover short stretches. The closest option to traveling the canal is a self-skippered rental boat, chartered by the night from Macedon.
Is the Erie Canalway Trail the same length as the canal?
No. The trail runs 360.3 miles from Buffalo to Albany, slightly longer than the 338-mile canal, because the path does not follow the water route exactly. The trail network totals 423.7 miles and is part of the 750-mile Empire State Trail.
