Sierra de los Padres is a hill-country town of country properties in the General Pueyrredón district, a few kilometres from Mar del Plata, in the southeast of Buenos Aires province. Set among low hills, stands of trees, lagoons and country air, it offers a green, easygoing contrast with the coastal city, and it is a classic getaway and day-in-the-country destination for anyone summering in Mar del Plata or looking for quiet near the sea.
The town is residential in character, built around country properties, with houses among the trees, plant nurseries, smallholdings and a much-appreciated country food scene: grill houses, tea houses and restaurants. Nearby Laguna de los Padres, in a municipal forest reserve of some 687 hectares, adds nature, walks and outdoor activities, and preserves historic sites linked to the old Jesuit mission that gave the area its name. It is an ideal setting for combining nature, rest and good food.
This guide covers the essentials of Sierra de los Padres with a practical eye: the hill-country town and its country properties, Laguna de los Padres and its park, the Reducción de Nuestra Señora del Pilar, the José Hernández Museum, the country food scene, the outdoor activities, where to eat and sleep, and how to get there. It is an ideal destination for a quiet, green getaway minutes from Mar del Plata.
The area owes its name to the Reducción de Nuestra Señora del Pilar, a Jesuit mission established in 1746 beside what is now Laguna de los Padres by Fathers José Cardiel and Tomás Falkner to evangelise the Indigenous peoples (Puelche and Serrano); it was short-lived and was abandoned around 1751. Centuries later, Sierra de los Padres developed as a hill-country residential town of country properties, tied to tourism and to the Mar del Plata area. The full version is on the history page.

Origins, formation and what the sources say.
Five years. That was all the mission lasted that gave its name to one of the greenest corners of the Buenos Aires coast. On 13 November 1746, two Jesuits —one a cartographer, the other a convert English physician— planted a cross beside a lagoon the Indigenous peoples called Vuulcan, determined to found a mission there in the middle of frontier territory. Five years later the mission no longer existed. But the name outlived it: today, almost 280 years on, the hills and the lagoon are still called 'de los Padres', in memory of that failed attempt at evangelisation.
The Reducción de Nuestra Señora del Pilar was one of three missions the Society of Jesus tried to establish on the Buenos Aires pampa in the mid-18th century —alongside Concepción de los Pampas, on the Salado river (1740), and Nuestra Señora de los Desamparados (1750)— in an effort to gather in and Christianise the nomadic peoples south of the colonial frontier. El Pilar set out to settle the Puelche and the hill groups of the region around the lagoon, weeks of travel from Buenos Aires, with no roads, no garrisons and no backing beyond the missionaries' own determination.
As with almost every mission on an open frontier, the venture was hard and short: it never reached the scale of the great Guaraní missions of the northeast and was eventually abandoned. What remained of that presence of the Jesuit 'padres', however, was the name that endures to this day and a handful of historic sites and references beside the lagoon, which fold the colonial past into today's hill landscape at Sierra de los Padres.
The Reducción de Nuestra Señora del Pilar was the work of two remarkable Jesuits. Father José Cardiel, a missionary and cartographer whose maps were key to European knowledge of Patagonia and the pampa, and Father Tomás Falkner, an English physician converted to Catholicism and author of a celebrated 'Description of Patagonia' (1774), reached the shores of the lagoon the local people called Vuulcan. There, on 13 November 1746, they planted the cross and started the mission, meant to gather in and evangelise the Puelche and the hill groups of the region.
The undertaking was arduous from day one. The territory was open frontier, far from Buenos Aires, and the Indigenous population was semi-nomadic and little inclined to the settled life the missions demanded. On top of supply problems and isolation came the growing hostility of the region's chiefs —among them the powerful Cangapol, called 'the Brave', lord of the encampments of the Río Negro and the south of Buenos Aires province—, who saw the missions as an advance guard of Spanish colonisation over their territories and their cattle trading routes. By 1751, barely five years after its founding, the Reducción del Pilar was abandoned.
Short as it was, the mission left a lasting mark. The lagoon and the hills came to be called 'de los Padres' in memory of those Jesuits, and the accounts of Cardiel and Falkner are early and hugely valuable testimony on the geography, the wildlife and the peoples of southeastern Buenos Aires province in the 18th century: for decades, much of what Europe knew of these lands came from the pens of those two missionaries.
A century after the Jesuits, this land watched the author of the most famous book in Argentine literature grow up. In 1846, after his mother's death, an eleven-year-old boy called José Hernández arrived in the fields of southeastern Buenos Aires province with his brother Rafael: their father worked as an estate manager in the area —Laguna de los Padres, Camarones, El Tuyú— and took his sons to live on the frontier. As Rafael himself, his first biographer, told it, in those years José 'became a gaucho': he learned to master a horse and came to know every task on a pampas estancia.
That childhood spent on horseback among ranch hands, campfires and country stores was the raw material from which, decades later, 'Martín Fierro' (1872) would come, the foundational gaucho poem of Argentine literature. The first-hand experience of rural life in Buenos Aires province —the language of the country people, the work of the land, the relationship with the Indigenous frontier— that Hernández absorbed as a boy in these parts is inseparable from the voice of his hunted gaucho.
The Laguna de los Padres estancia followed its own course: the main house you visit today was built in 1882, when the property belonged to Eusebio Zubiaurre, and in time it passed into public hands along with the land around the lagoon. In memory of the poet's years in these fields, the museum housed in the main house bears his name, and the figure of Hernández has been welded for good to the landscape of hills, trees and open water at Laguna de los Padres.
The Sierra de los Padres we know today —the park suburb of tree-lined streets, country properties and gardens— was born on a very precise day: 6 January 1950. That day the 'Barrio Residencial or Ciudad Jardín Sierra de los Padres' was officially created, a venture by the brothers Alfredo and Francisco Cobos and by Roberto Natalio Bonzo, who had bought the hill land to develop a subdivision inspired by the garden city model: generous plots, heavy tree planting, a layout adapted to the lie of the hills and rules that protected the green character of the whole.
The first years were pure pioneering. The development company, Alfranco S.A., built a water tower at the highest point of the subdivision and a power plant that supplied the energy to pump water and light the first properties and the few shops serving the earliest residents. Both water and electricity were provided free of charge... and at midnight the supply was cut off. Only in late 1958 did the provincial government run a high-voltage line from Mar del Plata toward Balcarce that passed through the area, and on 4 October that year a group of residents founded the electricity cooperative that still serves the town today.
Over the decades the park suburb consolidated into a hill-country town of country properties in the General Pueyrredón district, residential in character, with nurseries and plant and flower growing, and a country food scene —grill houses, tea houses, restaurants— that turned it into the classic green getaway for the people of Mar del Plata and their visitors.
For a long time the site of the old mission was marked only by memory and a few traces. The recovery of that heritage came only in the 20th century. On 11 March 1960, the Asociación Museo Tradicionalista Argentino José Hernández founded, in the old estancia house (the 1882 building), the museum devoted to rural life, gaucho traditions and local history, today the José Hernández Municipal Museum: riding gear, criollo furniture, farm tools and pieces that recreate the culture of southeastern Buenos Aires province.
A few years later, from 1968 onward, reconstruction work was undertaken near the original site of the Jesuit mission, producing the chapel and the buildings the public can visit today. So what you see at the Reducción de Nuestra Señora del Pilar are modern reconstructions evoking the spirit of the 1746 mission, not the original 18th-century buildings. Every 13 November, the anniversary of the founding, the site hosts religious celebrations and pilgrimages that keep that memory alive.
All this heritage is concentrated in the Laguna de los Padres Forest Reserve, a municipal park of some 687 hectares around the open water, combining nature, colonial history, gaucho tradition and recreation: picnics under the trees, silverside fishing, horseback riding, birdwatching. So the Laguna and the Sierra de los Padres bring together today, barely twenty minutes from Mar del Plata, almost three centuries of history in a single green landscape.
