The Month You Book Decides Which Monterey Whale You See

A narrated run over the canyon off Old Fisherman's Wharf. Gray whales in winter, humpbacks and blues from spring to fall.

Pick your month, then book a Monterey whale trip.

Monterey Bay sits over one of North America's largest deep ocean canyons, and the whale boats work that edge every day of the year, weather permitting. The trip is built around one rule that shapes everything else. The crew stops the boat at least 300 feet out and lets the whale decide whether to come closer. That distance comes from the federal whale watching guidelines. Nothing gets chased. Princess Monterey runs the two largest boats in the Monterey fleet, the 110-foot Princess Monterey and the 100-foot Atlantis Monterey, and every trip is narrated by crew that includes marine biologists and naturalists.

Trips run roughly two and a half to three hours. The operator recommends booking ahead and singles out summer months and weekend departures as the ones that fill first.

Gray Whales in Winter, Blues and Humpbacks in Summer

The operator splits the year in two. December through April is gray whale season, when the migration passes Monterey between the Bering Sea and the lagoons of Baja California. April through November turns the bay into a feeding ground, and that half of the calendar brings humpbacks, orcas and blue whales, along with Risso's dolphins, northern right whale dolphins and Pacific white-sided dolphins. California sea lions, harbor seals and southern sea otters are around through both halves. Pick the month and you have picked most of the list.


The Paid Upper Deck Is Not Always the Better Seat

Both boats sell a limited upper deck upgrade, twenty dollars per person on this booking page, paid at check-in when space is left. The operator's own seating advice is worth more than the price tag. The upper deck sees further out and suits photographers, while the lower deck sits closer to a whale that decides to swim over and inspect the boat. The crew call that a mug. Mid-ship on the lower deck also moves least, which matters if you get seasick. Each vessel has a 360-degree walk-around deck and a heated cabin with large windows. No seat is a dead end.


No Guarantee, and a Rain Check If the Bay Stays Empty

How far you travel depends on where the food is. The operator puts the range at two to sixteen miles from the harbor, which separates a short hop from an afternoon well offshore. Sightings are never promised. The operator reports a 98 to 99 percent success rate across the year and issues a rain check for a future trip when a boat finds neither whales nor dolphins. The booking page runs its own cancellation rule on top of that: cancel at least 24 hours before departure for a full refund.


Finding the Yellow Building, and Staying Upright

Check-in is at 96 Fisherman's Wharf, the bright yellow building at the end of Old Fisherman's Wharf with a red, white and blue sign on the roof. Arrive 30 minutes before departure, and take motion sickness medication a full hour before boarding rather than once you feel it. Princess Monterey leaves at 9:00 AM, 12:30 PM and 3:30 PM, Atlantis Monterey at 10:00 AM, 2:00 PM and 5:00 PM, both subject to change. Park in the Fisherman's Wharf lot at Del Monte and Washington and walk along the water. Dress in warm layers, long pants, a windproof jacket and flat closed-toe shoes. Both boats run a snack bar, and you can carry on your own food and non-alcoholic drinks. Children under 3 and expecting mothers cannot sail. The booking page also lists advisories for travelers with back or heart conditions, which the operator's own site does not repeat.

Monterey Bay National Marine Sanctuary was designated in September 1992, and every one of these departures crosses it. The canyon under the hull is the short answer for why the animals are here at all.
