Join us for a fun, thrill-of-a-lifetime day tour in the Sea of Cortez looking for blue and fin whales that cruise the waters of Loreto Bay National Marine Park/UNESCO World Heritage site.  While whale sightings are not guaranteed, this is one of the few places on Earth to see these deep-ocean creatures with regularity. The islands off Loreto are often referred to as the “blue whale corridor.”  Generally, late January to early March is the best time to see these whales near Loreto.  This is a full-day tour and each boat is limited to six passengers.

Blue Whales

As youngsters, many of us were fascinated by dinosaurs. Yet the blue whale is much bigger than any dinosaur that ever lived! In fact, they are the largest animal to ever inhabit the earth, with a body mass equal to 24 elephants and a mouth that could swallow a railroad boxcar. To see one of these massive animals in the Sea of Cortez is a true wildlife watching highlight.  

Blue whales can be 80-100’ (27-30 meters) in length, and weigh as much as 140-150 tons.  Their heart is the size of a small car (think of a Ford Focus or VW Beetle) and pumps some 10 tons of blood through their bodies.  To get a sense of their size, think of yourself compared to a mouse.  We are the size of a mouse compared to a blue whale.  

At one point in time, it’s estimated there may have been 200-300,000 blue whales in the earth’s oceans. Whaling took a tremendous toll. Today the population is estimated at around 12,000 -15,000 but is slowly growing.  They eat 3-4% of their weight each day, mostly krill.  When they swim, they cruise around 6-10 miles an hour but can go much faster if necessary.

They are a very loud animal that communicates using deep rumbling sounds. Scientists and divers say they feel these more than hear them. They can communicate with each other over distances of 500-800 miles and while they don’t have external ears, their flesh and bone carry the sounds to their skull-buried ears.

In the summer months, blue whales travel to cool polar waters to feed. In the winter they travel south to tropical waters and this is when we see them in the Gulf of California.  Watching blue whales takes some patience.  Normally after they surface, they will dive for five to twenty minutes, going perhaps 150-300’ (50-100 meters) below the surface.  Then they rise to the surface to breathe.  They have two blowholes and blow frequently.  When they are on the surface we are rewarded by seeing them. Usually, they will blow for ten to twenty seconds and stay on the surface two to six minutes.

Fin Whales

Fin whales, the second largest whale in the world, are more common and equally breathtaking. They have a distinct ridge along their back behind the dorsal fin, which is why they are also known as "razorbacks.” One of their most fascinating features is that their lower right jaw is bright white and the lower left jaw is black.  They are fast swimmers and mostly live in the open sea.  However, a certain number visit the Gulf of California each winter.

Note that we also offer our Whale Extravaganza tour that includes watching blue whales near Loreto combined with a stay at our Magdalena Bay whale camp to see the gray whales.

The whales of Baja are waiting to welcome you to their world!  We invite you to join this full-day whale watching tour, or one of our other great Baja whale watching tours.
