This park was established to protect this unique environment, which also includes other marine species such us dolphins, turtles and many others. From August to October the southern hemisphere whales finish their journey to Whale Bay (Bahia Ballena) for this instinctive and beautiful act of having offspring. Humpbacks visit this area from December to April.

Female whales along with their babies perform water gymnastics and a unique symphony heard for hours both in and out of the water. After three months, when the whale calf has learned how to survive, the mother will start the journey back to cold waters.
