Every autumn, thousands of Gray whales make their annual 6,000 mile migration from the summer feeding grounds of Alaska to the calving grounds of Cabo San Lucas, the Baja and the Sea of Cortez. If you're coming to Cabo San Lucas between December 15 and March 31, you will likely be treated to seeing some of these gentle giants. Whether you like the speed and excitement of the Ocean Riders Tour, or the relaxation and luxury of one of the larger boats, you're sure to love whale watching in Cabo San Lucas.
