To the south of the San Jorge Gulf, 300 km from Comodoro Rivadavia is Puerto
Deseado. The Puerto Deseado Estuary is one of the largest marine reserves
of the planet, a coastal area that arose after being submerged for a long
time. The marine birds that inhabit its coasts and the abundant fish in its
waters form this rich fauna reserve. Among them, the cormorants penguins,
seagulls, skuas and oyster-catchers stand out.
During the summer this is the habitat of the one-hair and two-hair sea lions,
sea elephants and right whales. But the biggest attraction is, undoubtedly,
the tonina overa: a most beautiful black and white dolphin that mates in the
bay. From October to April the Magellan penguin arrives here to feed and mate.
