Peninsula Valdes is a UNESCO World Heritage Site located in the Argentine Patagonia, about 100 km east of Puerto Madryn. The peninsula is a unique natural reserve with a great diversity of flora and fauna. It is an important breeding ground and refuge for various marine mammals, such as southern right whales, elephant seals, and sea lions. It is also a nesting place for penguins, cormorants, and other seabirds. The area is also a popular spot for marine wildlife watching and ecotourism.

The peninsula itself is a narrow strip of land that extends 80 km into the Atlantic Ocean, creating two gulfs on either side. The landscapes of Peninsula Valdes are stunning, with cliffs, beaches, and deserts. The protected areas of the peninsula are home to a number of different habitats, including salt flats, sand dunes, and grasslands. The fauna of the area also includes guanacos, maras, and rheas, among other species.

The best time to visit Peninsula Valdes is from June to December, when the whales can be seen from the shore. However, the area is beautiful all year round and there are plenty of activities to do, such as trekking, birdwatching, and visiting the small towns that surround the reserve. The main gateway to the peninsula is Puerto Madryn, a popular beach destination and the largest city in the region.
