Whale Watching from La Paz: Gray, Humpback + Blue Whales

Every winter, some of the biggest animals on Earth arrive in the waters around Baja California Sur to give birth, breed and feed. From a base in La Paz you can reach three very different whale experiences: gray whale mothers and calves on the Pacific side, singing humpbacks off Los Cabos and blue whales near Loreto.

Gray whales in Magdalena Bay

Each year gray whales migrate down from their Arctic feeding grounds to the calm lagoons of Baja's Pacific coast. Magdalena Bay is famous for mothers and calves, and the whales are often curious about the small boats, called pangas, that take visitors out.

• When: roughly January through March, with tours winding down by mid-April.
• Getting there from La Paz: Magdalena Bay is on the Pacific coast, a long day trip by road. Many visitors go with a tour that includes transport.

Humpback whales off Los Cabos

Humpbacks come to the warm waters off Los Cabos to breed and calve, and that's when you'll see breaching, tail slaps and, if you're lucky, hear males singing.

• When: Los Cabos' official whale-watching season runs from December 15 to April 15.
• Getting there from La Paz: Los Cabos is about a two-hour drive south, so it's an easy day trip.

Many of the humpbacks that winter in Mexico belong to what the US National Oceanic and Atmospheric Administration (NOAA) calls the Mexico distinct population segment, listed as threatened under the US Endangered Species Act.

Blue whales near Loreto

The largest animal ever known feeds in the protected waters of Loreto Bay National Marine Park, north of La Paz.

• When: roughly January through March, with some guides citing mid-December to April.
• Getting there from La Paz: Loreto is several hours north by road, so plan it as an overnight trip.

Whales in the Bay of La Paz

Whales also pass through the Sea of Cortez near La Paz in winter and spring, and you may spot them from a boat on an island or snorkel day. Sightings close to town aren't guaranteed, so for a dedicated whale day, pick one of the trips above.

Watch whales responsibly

• Go with a permitted operator. Mexico sets official whale-watching seasons and rules for boats.
• Let the whales set the pace. Good captains approach slowly, keep their distance and never chase or box in a whale.
• Keep it calm on board: stay seated when asked and keep noise down.
