Isla Escondida is a vast beach located on the Atlantic coast, about 65 km south of Rawson, on the way to the Punta Tombo reserve. It is a rarely visited site of great natural value, where it is possible to observe southern elephant seals (Mirounga leonina) from the shore, at a very short distance. During the visit, we will enter the beach to walk through the observation area and spend approximately one hour there, enjoying the stunning scenery and watching these large marine mammals in their natural environment. Depending on the time of year, it is possible to spot adult males, females, and pups. Males can reach up to 5 meters in length and weigh over 3,500 kg, while females are smaller, about 2.5 to 3 meters long and around 800 kg. Elephant seals spend nearly 70% of their lives in the water, but during the breeding and molting seasons, they rest on the Patagonian beaches.
