Monte Hermoso is a town located on the Atlantic coast of Argentina, some 100 km (62 mi) east of the city of Bahía Blanca, in the south of the Province of Buenos Aires.

Founded at the beginning of the twentieth century, Monte Hermoso is a family seaside resort with more than 32 km (20 mi) of beach overlooking the Atlantic Ocean and with the unique characteristic in Argentina of having both sunrises and sunsets over the sea.

The summer climate of Monte Hermoso is more temperate than that of other major seaside resorts due to the sea breeze effect,[1] while the water itself is warmer,[2] making for a pleasant beach experience.

Monte Hermoso owes its existence to the 1879 purchase of 4,000 seaside hectares (10,000 acres) by Esteban Dufaur.

[3] The lighthouse, Faro Recalada a Bahia Blanca, 73 m (240 ft) high and the tallest in South America, is situated on the coastal road to Sauce Grande about 7 km (4 mi) east of the resort, where it marks the route to the nearby port of Bahía Blanca.
