January – March | Experience the Majesty of Blue Whales in Loreto Bay, Baja California Sur

Every winter, the calm waters of the Sea of Cortez welcome one of nature’s greatest spectacles: the arrival of the blue whale in Loreto, Baja California Sur. Blue whales — the largest animals to ever exist — come to Loreto to mate and give birth, finding safety within the protected waters of the Loreto Bay National Marine Park.

At Aventuras Tours, we are fully prepared with two well-equipped boats, offering a safe, comfortable, and ethical whale watching experience, always in small groups.
