If you type "aml whale watching" you are looking at the largest operator on the St. Lawrence estuary. Croisières AML runs whale departures from two docks inside the Saguenay–St. Lawrence Marine Park — Tadoussac on the north bank, Baie-Sainte-Catherine in Charlevoix on the south — and it is the only company there selling both a big glazed observation boat and zodiacs. Adult fares start at C$99.99 for the short zodiac and C$134.99 for the three-hour boat, according to croisieresaml.com, before tax.
What Croisières AML actually is
A family business founded in 1972 and still owned by the Hamel family, according to its own about page. The same page puts the company at 25 ships, 10 Québec ports, more than 750 employees and over 650,000 passengers a year, which makes it the largest cruise-excursion company in Canada rather than a whale specialist. Whales are one line of a business that also sells dinner cruises in Montréal and city boat tours in Québec City.
That scale cuts both ways. You get certified naturalist guides, crew and vessels certified by Transport Canada, and a written re-ride clause — rare in this industry. You also get a boat that can carry a few hundred people, so the quiet-small-boat experience is not what is on sale here. AML describes itself as a partner of Green Marine and a founding member of the Eco-Whale Alliance, the Québec grouping that sets observation practice inside the marine park, whose rules are stricter than Canada's general ones.
One marketing line deserves correcting. AML's listings promise "up to 13 species". The marine park's own authority says nine species of marine mammals regularly frequent its waters — belugas, harbour, grey and harp seals, harbour porpoises, and minke, fin, blue and humpback whales. On a three-hour sailing, three or four of those is a good day.
Boats, zodiacs and what the difference costs you
The three-hour boat product runs on the AML Grand Fleuve: two fully glazed indoor lounges with 180-degree views, exterior observation decks, restrooms and a bistro. Two upgrades sit on the same sailing — an upper observation deck capped at 30 passengers, and the glass-enclosed St. Lawrence VIP Lounge capped at 20, with a platter of regional products and bar service. Departures are 9:45 and 13:00, and the trip runs three to three and a half hours depending on tides.
The zodiacs come in two sizes, 24 and 60 passengers; a naturalist guide rides the 60-seaters, while the 24-seaters carry an experienced captain who does the commentary. A waterproof, windproof suit is provided. The 2.5-hour expedition departs at 10:15 and 13:30 and ends with a run into the Saguenay Fjord; a shorter two-hour version leaves at 08:00 and 16:30.
Published adult fares, before tax and varying by date: C$134.99 on the boat, C$169.99 with upper-deck access, C$209.99 in the VIP lounge, C$134.99 on the 2.5-hour zodiac and C$99.99 on the two-hour zodiac. The boat season runs early May to the start of November; the 2.5-hour zodiac runs a similar window, and the cheaper two-hour zodiac is sold only from the end of May to late September.

The zodiac and the bus-and-cruise day from Québec City sit in different groups:
The zodiac carries the biggest review count of any Canadian whale product in our partner feed, and the 3-hour boat tour is the next biggest in Québec — useful, because volume on that scale makes a rating harder to game, and both sit in the low-to-mid fours rather than the near-perfect scores small products collect. We could not confirm the supplier line on the GetYourGuide listing itself: the product pages return 403 to us, so treat the match to AML as strongly implied by the title and departure pattern rather than confirmed.
The whale warranty, read closely
Two details matter. First, the pass is for a boat tour, so if you sail on the zodiac and see nothing, your compensation is a seat on a different product. Second, AML explicitly includes bookings made through an online travel agency, which is unusual — most operators void their guarantee the moment a third party is involved.
There is also a wrinkle worth catching before you pay. The zodiac listings on AML's own Tadoussac page carry the whale guarantee in their sales copy, promising another boat cruise at no charge if nothing is seen, while the dedicated Whale Warranty page states the pass is not valid for a zodiac whale-watching cruise. Both are AML pages. Read the terms page as the binding one, and if the zodiac's promise is what sold you the trip, get it confirmed in writing when you book.
Practical detail only this page gives you
Take AML's own tip seriously: driving up from Québec City or Montréal for a single day, book the Baie-Sainte-Catherine departure. The Tadoussac ferry is free and runs year-round, every 13 to 60 minutes by season, but in July the vehicle queue is what makes people miss a 13:00 sailing.
Inside the marine park, boats must stay at least 400 m from belugas, blue whales and North Atlantic right whales, and 200 m from minke, fin and humpback whales, according to the park authority. Nobody is getting you alongside a beluga; that is the law working. Dress for ten degrees colder than the village and bring binoculars.
How it compares on this water
Croisières Essipit is the Innu-owned alternative out of Les Bergeronnes, zodiac-only and cheaper, with no published sighting guarantee. Mer et Monde Écotours is the kayak option from Tadoussac beach and Anse à la Cave. If you want the whole Tadoussac picture, including land viewing at Cap-de-Bon-Désir, start at the Tadoussac port page; for the bus-and-boat version see whale watching from Québec City, and for the species you are actually chasing, belugas and blue whales.
Verdict
Book AML when you want the comfortable, high-capacity version of a St. Lawrence whale day, a naturalist on the microphone and a re-ride clause in writing. Book the zodiac for the fjord run and the water-level view, but read the warranty first — it will not cover you. Check the boat and zodiac prices on both AML's site and the platform before you pay; the gap moves with the date.
