Jun – Aug
Summer
Both cruises run their full timetable. This is what “make the most of the summer months” means on the Bateau-Mouche listing — it is the boat’s main season.
By boat instead
There are exactly two river cruises worth comparing in Montreal, in the same way there are exactly two helicopter flights over the city. Le Bateau-Mouche runs a 90 min St Lawrence cruise from $32; the guided sightseeing cruise runs 3.5 h from $35 with live commentary included. Either Montreal boat tour puts you on the water in front of the Old Port for a fraction of the $161 helicopter flight above the same river. This page is the two boats, side by side, and where each one fits.

Quick answer
The short answer. A Montreal boat tour is the honest alternative to the helicopter flight if $161 is more than you want to spend. Le Bateau-Mouche sails 90 min from the Old Port for $32, rated 4.2 across 2,306 reviews. The guided sightseeing cruise runs longer, at $35 for 3.5 h, and adds a live guide narrating the Old Port, the Biosphere and the Jacques Cartier Bridge as you pass them. Neither boat leaves the ground — for that, the helicopter flies thirty minutes over the island from $161.
The alternative
Same river, much longer on the water, a fraction of the flight’s price.
Montreal only sells one helicopter flight over the city itself, and it costs $161 for thirty minutes. That is a real number, not a marketing one, and for a lot of people planning a trip it is simply more than the budget for one afternoon. A Montreal boat tour is what is actually on sale instead: the same river, a much longer time on the water, and a price that starts under forty dollars.
The two are not the same thing and this page will not pretend otherwise. A helicopter puts the whole island under you at once — the Olympic Stadium, downtown, Mont Royal, the bridge — in half an hour. A boat tour in Montreal stays level with the skyline and moves past the Old Port at walking pace, which is a completely different way of seeing the same city. What the boat adds back is time: ninety minutes to three and a half hours on the water for less than a quarter of the flight’s price.
Searches for a Montreal jet boat tour turn up nothing bookable on this page, and it is worth saying so plainly: both cruises below are slow sightseeing boats built for photographs and commentary, not speed. If a fast ride on the river is what you actually want, neither listing here is that.
The two cruises
Both sail from the Old Port. What separates them is length, commentary and price.
The older and busier of the two: a stable, glass-topped boat that has been running the same stretch of river for decades. It sails 90 min for $32, rated 4.2 across 2,306 reviews, and Montreal residents still call it the default Old Montreal boat tour when they mean a short one.
This is the Montreal boat cruise tour for people who want a guide talking through what they are looking at rather than working it out themselves. It runs 3.5 h for $35 with live commentary on the Old Port, the Biosphere and the Jacques Cartier Bridge, rated 4.2 across 2,259 reviews.
Neither cruise below is sold as an evening-only sailing — both run through the day, and the exact departure times are shown at checkout rather than fixed on this page. If catching the light low over the river matters to you, book the later time slot on offer.
Both listings here are shared sailings with other passengers on board, not a private charter. That keeps the price at $32 and $35 rather than what a boat booked just for your group would cost.
Neither operator advertises the boat itself as electric — that detail simply is not part of either listing, so this page will not claim it.
Choosing between them
The short, cheap cruise or the longer, narrated one — both leave from the same dock.
Price decides this for most people. Le Bateau-Mouche is the cheaper Montreal boat tour at $32, and at $32 for 90 min it is the pick when the plan is a quick look at the river between other things in the day.
The guided sightseeing cruise costs a little more, at $35, and earns the difference with time and narration: 3.5 h instead of 90 min, and a guide naming what you are passing instead of leaving you to work it out from a map. For a first visit to Montreal, that context is worth the extra few dollars.
Neither listing sells itself on speed. Le Bateau-Mouche’s own description calls the boat “stable and nimble” rather than fast, which matches what both cruises are actually built for: a level, steady view of the skyline rather than a thrill ride on the water.
Both are a Montreal boat tour in the plain sense of the phrase — a scheduled sightseeing boat you book a seat on, not a private hire. Rated 4.2 and 4.2 respectively, across a combined 4,565 reviews, they are also two of the most-reviewed listings on this entire site, well ahead of either helicopter flight.
When to go
Le Bateau-Mouche is a warm-weather boat; the guided sightseeing cruise runs a longer season.
Jun – Aug
Both cruises run their full timetable. This is what “make the most of the summer months” means on the Bateau-Mouche listing — it is the boat’s main season.
Sep – Oct
The guided cruise keeps sailing and the light on the river turns gold in the afternoon. Confirm the Bateau-Mouche schedule before you plan a day around it this late in the year.
Nov – Mar
The St Lawrence is not a summer-boat river in winter. Neither cruise is a sensible plan for this stretch of the calendar; the helicopter and the walking tours keep running instead.
Apr – May
The season restarts as the ice clears. Book a little ahead rather than assuming the first warm weekend already has sailings on sale.
Boat, walk, bus or flight
Four ways to see the same river and skyline, four very different prices.
The St Lawrence and the skyline above it can be seen four different ways from this site, and the price gap between them is wide. A Montreal boat tour starts at $32 and stays on the water for 90 min to 3.5 h. The guided walking tour through Old Montreal, a short walk from the same dock, is $25 for 2 h on foot rather than on the river. The guided bus tour covers more ground in less focused detail for $51 over 3.5 h. And the helicopter flight, the most expensive option on this entire site by a wide margin, is $161 for thirty minutes above all of it at once.
None of the four is a wrong choice — they simply answer different questions. If the question is “how do I see the water without spending much,” a Montreal boat tour answers it directly. If the question is “how do I see everything at once,” only the flight does that, and only the flight costs $161.
Who each cruise suits
Both cruises are on this page for a reason; here is who each one actually fits.
Le Bateau-Mouche at $32 is the cheapest way on this whole site to get onto the St Lawrence, and for a lot of visitors that is the entire decision.
The guided sightseeing cruise at $35 adds a live guide naming the Old Port, the Biosphere and the Jacques Cartier Bridge, which matters more on a first trip than a repeat one.
Both cruises dock in the Old Port, a short walk from the district covered by the Old Montreal walking tour, so pairing a morning walk with an afternoon cruise needs no extra transport.
Anyone weighing the $161 helicopter against a Montreal boat tour is really weighing thirty minutes above the whole island against 90 min to 3.5 h on the water for a fraction of the price.
Neither cruise is a realistic plan outside spring through autumn. The helicopter and the two walking tours are the options that keep running through a Montreal winter.
What each listing actually says
Taken directly from the two listings, not guessed at.
The operator describes it as a “stable and nimble vessel,” sailing “in and out of Montreal’s Old Port” with panoramic views from the water — built for calm, comfortable sightseeing rather than a fast ride.
The listing promises “live commentary from an expert guide” naming landmarks as you pass, including the Old Port, the Biosphere and the Jacques Cartier Bridge — the detail that separates it from the shorter, cheaper Bateau-Mouche sailing.
For comparison, the flight listing covers the Olympic Stadium, downtown Montreal, Mont Royal, Parc Jean Drapeau, the Jacques Cartier Bridge and the St Lawrence River in one pass — the same bridge and river, from above rather than alongside.
Neither listing describes a private charter, a night sailing or an electric boat — three things people search for that simply are not part of what is on sale here.
Still deciding whether the flight is worth the extra money? It is thirty minutes over the whole island, from $161.

Common questions
For a first visit, the guided sightseeing cruise is the easier pick: $35 buys 3.5 h with a live guide naming the Old Port, the Biosphere and the Jacques Cartier Bridge as you pass. Le Bateau-Mouche is the faster, cheaper option at $32 for 90 min if you just want time on the water.
Le Bateau-Mouche starts at $32 and the guided sightseeing cruise at $35. Both are shared sailings from the Old Port, not private charters, which is why the price stays well under the $161 helicopter flight.
Yes — both cruises on this page dock in the Old Port, on the water edge of Old Montreal, so no separate transfer is needed before or after either sailing.
No. Both listings are slow sightseeing cruises built for photographs and commentary, not a speed ride on the river.
They answer different questions. The helicopter shows the whole island at once for $161 in thirty minutes; a boat tour in Montreal stays level with the skyline for 90 min to 3.5 h and costs a fraction of the flight.
No. Le Bateau-Mouche runs through the summer months and the guided cruise keeps going into autumn, but neither sails through a Montreal winter. Check the exact dates at checkout before you plan around either one.
