This Tuesday August 30, it’s the International Whale Shark Day and also the date when their season officially begins. Each year, an average of 30 of these critters – the largest fish in the world – visit La Paz and Cabo San Lucas, becoming an attraction for locals and tourists alike until March, when they move to greener pastures – bluer waters?  The gentle giants—which can reach up to 40 feet (12 meters) or longer in length, and weigh an average of 5 tons, are so nice that they let you dive with them. Enjoy!
