Las Grutas is a beach resort located in the Atlantic coast of the province of Río Negro, only 15 Km. from San Antonio Oeste, district it belongs to. Its history is a short one but full of present.

It is said that the first house in Las Grutas was built in 1939 by people from San Antonio Oeste. But only in 1964, after the allotment of the land, this beach village started to spread widely. In the 80’s it got a great backing from the investments coming from people from different cities of the region and then the official support with the arrival of the essential services such as water supply, electricity, etc.

Balneario Las Grutas, PATAGONIA ARGENTINAThe name comes from the caves undermined by the sea in the cliff.

Its beauty resides in a beach sheltered by the cliff, and mainly the warmth of its waters, which can reach 25 degrees Celsius in some areas.

No doubt it’s the hottest beach village on the Patagonian coast. Its growth in the last years has been huge. It already looks like a small city. With an infrastructure installed according to its visitors, Las Grutas is a paradise for those who love long days of beach and sun.

Its main attractive consists of its magnificent beaches, white sand and deep blue, transparent waters, which are the warmest in Argentina.
Being in the very heart of San Matías Gulf, and having medium sized cliffs, this place has little or no wind at all, something incredible for Patagonia. The width of the tides, the system of circulation of the coast currents, the high temperatures in summer and the scarce rains are contributing factors to this phenomenon.
