Every winter, gray whales finish a migration of thousands of kilometres from the Arctic and arrive in the warm, shallow lagoons of the Baja California Sur Pacific coast to give birth and nurse their calves. Magdalena Bay is the lagoon system closest to La Paz, and it is one of the best places in the world to see the whales at close range. Small open boats called pangas take a handful of passengers out onto calm water, the engine is cut when whales approach, and the animals, which are famously curious, may swim alongside, roll beside the hull or lift their heads out of the water. Some mothers even nudge their calves toward the boat, which is why local guides call them the friendly whales. This is not a quick outing from the city: Magdalena Bay is across the peninsula, so the experience is a full day or longer, and it rewards visitors who plan their trip around the season. It pairs naturally with a winter stay in La Paz, when sea lion swimming and the end of the whale shark season overlap with the gray whale window.
How it works
The excursion leaves La Paz early, usually with a pickup from central hotels, and crosses the peninsula by road to the lagoon coast, where you transfer to a small boat with a local captain and a guide. The time on the water is a few hours, and the rest of the day is travel, so expect a very long day and bring something to read or listen to on the drive.
Some operators run the same trip as a longer outing with an overnight stay, which gives more time on the water and fewer hours on the road. Check the tour details for the meeting point, the pickup times, what meals and drinks are included and whether park or community fees are paid separately.
When to go
The gray whales are a winter visitor, with the best viewing generally from about January to March and the first and last weeks of the season quieter. Outside that window the lagoons are empty of whales, so do not book the trip for summer. Weather is cool on the water in the early morning, and the Pacific side can be windy, so bring a warm layer, a windproof jacket, sunglasses, a hat and sunscreen.
A waterproof cover for your camera or phone is worth having, because whales surfacing next to the boat can spray everyone aboard.
Etiquette and safety
Whale watching in the lagoons is regulated, and the captains follow rules about how close boats may approach and how many may be on the water at once. The whales decide whether to come over, and the experience is better when you stay calm, keep your hands inside the boat unless your guide invites you to reach out, and never try to touch or feed an animal on your own.
Life jackets are worn throughout. Anyone prone to motion sickness should take a tablet beforehand, as the lagoon can be choppy in wind.
Plan around it
Build the trip into a winter itinerary, ideally on a day when you have no other early boat outing, and keep a spare day in case operators move the date because of wind or port closures. Combine it with a gentler city day on the Malecón and the museums, and with the Isla Espíritu Santo boat trip, which also runs in the cooler months. If you only have a short stay and the dates do not line up, the sea lions and whale sharks around La Paz will give you plenty of wildlife without the long drive.
What to expect
The experience
A guided expedition from La Paz across the peninsula to Magdalena Bay, with a few hours in a small boat among gray whales and their calves.

How long
A full day, most of it spent on the road, or a longer overnight version with more time on the water.
Tips
Bring warm and windproof layers, sun protection, a waterproof cover for your camera, a snack and a motion-sickness tablet if you need one.

Good questions
When can I see gray whales?+
The whales are in the lagoons in winter, with the best viewing generally from about January to March. Outside those months there are none, so plan your dates around the season.
How long is the trip from La Paz?+
Magdalena Bay is across the peninsula, so most of the day is spent travelling. Expect a very early start and a late return, or choose a longer version with an overnight stay.
Will the whales really come close to the boat?+
Often they do, because the gray whales in the lagoons are known for approaching boats out of curiosity. It is never guaranteed, and the captains follow rules about how close they may go.
What should I wear?+
Dress in warm layers with a windproof jacket, plus a hat, sunglasses and sunscreen. A waterproof cover for your phone or camera is useful because of spray.
Is it suitable for children?+
It can be a wonderful trip for older children, but the long drive and open boat are demanding for the very young. Ask the operator about age limits before you book.
