Trips run late May to early October, peaking in July and August, and cost $84 per adult. The feeding grounds lie 20 to 30 miles offshore near Mount Desert Rock, so trips take 3 to 5.5 hours.
Dark months are the peak for that species, light months are the rest of its season. October is marked.

Whale watches leave from 1 West Street, next to the Bar Harbor town pier, where the ticket office will also print tickets for anyone who booked online. The free Island Explorer buses, which run for most of the season, stop at the Village Green a short walk away, and taxis can drop off at the dock. Passengers over 18 need a valid photo ID, and Maine residents must show one for the local fare.
Downtown and town pier parking is municipal and paid, through kiosks or the ParkMobile app. Because trips run long, the operator recommends the lots with blue-marked kiosks, and it warns that spaces get scarce later in the day. From the pier, boats head into the open Gulf of Maine. The Maine.com guide puts the feeding grounds 20 to 30 miles offshore, often around Mount Desert Rock. That granite ledge, about 25 miles south of the island, has a lighthouse and a College of the Atlantic research station.
Humpback, finback and minke whales are the three baleen species Bar Harbor Whale Watch Co. lists, along with porpoises, dolphins, seals, sharks, ocean sunfish and offshore seabirds. Trips run from late May to early October. The Maine.com guide puts the peak in July and August and says late September often still brings strong sightings with smaller crowds. Research interns from Allied Whale at the College of the Atlantic ride every trip to collect data.
Maine.com calls humpbacks the species most often active at the surface: they breach, slap their pectoral fins and raise their flukes to dive, and the pattern under each tail identifies the animal. Finbacks, the second-largest animal on Earth after the blue whale, rarely breach. Minkes usually surface once and slip away. North Atlantic right whales are critically endangered, and federal law keeps boats 500 yards from them, so crews pull back when one is spotted. Atlantic white-sided dolphins sometimes ride the bow wake.
Swell decides whether a trip sails. Maine.com says boats cancel on clear days when a big swell is running. Mornings tend to be calmer, since the wind picks up as the day goes on, so the guide suggests the earlier departure on a breezy forecast. The company can call off a trip as late as 30 minutes before departure and notifies passengers by email and text. Before leaving the dock, the captain announces sea conditions, and anyone can step off to reschedule or take a refund.
Dress for water about 20 degrees colder than town. Maine.com's example is a 75-degree afternoon on Main Street that feels like 55 out at Mount Desert Rock, with cold spray, so pack a windproof layer, a hat and sunglasses against the glare. The operator asks for sturdy, flat, closed-toed shoes and sunscreen. For seasickness it suggests the back of the boat or the main level, fresh air and a view of the horizon, plus Bonine or non-drowsy Dramamine 1 to 2 hours before departure.
Whale watches meet more variable seas than the company's cruises in sheltered Frenchman Bay, and they last longer, so more people feel queasy on them. Medication does little once the boat is underway. The operator adds that children get seasick more easily and should stay hydrated, out in the fresh air and away from sugary or greasy food.
Bar Harbor Whale Watch Co. runs the only dedicated whale trips from Bar Harbor. Maine.com says the town's other boats, including Downeast Windjammer's schooner Margaret Todd, Acadian Boat Tours and Lulu Lobster Boat Ride, stay in Frenchman Bay and do not go out to the whales. The whale watch costs $84 for ages 15 and up, $72 for ages 6 to 14 and $35 for children 5 and under. Maine residents with photo ID pay $67.50.
The company's fleet includes jet-powered catamarans of 100 ft (Coastal Explorer), 112 ft (Friendship V) and 130 ft (AtlantiCat), and it says AtlantiCat reaches 30 knots. It does not say which boat runs a given whale watch. A guide narrates the natural and cultural history of the Gulf of Maine, and the company has taken part in the Whale SENSE program since 2012. Wheelchair users can reach the main deck and its amenities on each of those boats.
If no whales are seen, the ticket becomes a voucher for another whale watch or a harbor cruise within three years, and there is no cash refund. Cancelling or rebooking needs 24 hours' notice to the ticket office. When the company cancels, refunds go back automatically by the end of the day. Galley purchases and the $10 binocular rental are cash only.
