Every year in the month of January the Islands within the Loreto Bay National Marine Park are home to 9 species of whales; the blue whale, fin whale, sei, sperm whales, minky, pilot, orcas, humpbacks and a few gray whales.

These giant mammals can reach up to 30 meters in length and weigh almost 150 tons, and we can often see them at a distance almost within reach of our hand. Due to the fact that blue and fin whales break the sea surface about 2 to 6 minutes after their long dive, and travel at a speed of 15 kilometers per hour, it is important to understand many variables, which will determine the diving time which can be up to 25 minutes, and the place where the whale will surface.
