🇦🇷 Argentina · Buenos Aires
Santa Teresita and San Bernardo are two of the busiest beach towns in the Partido de la Costa, at the northern end of the Buenos Aires Atlantic coast (the Tuyú region), part of the run of adjoining resorts stretching from San Clemente del Tuyú to Mar de Ajó. They're lively family holiday destinations with a wide range of services, known for their long beaches, their pedestrian shopping streets and a bustling atmosphere in season.
The beaches here are wide, with fine sand and calm, shallow water, ideal for families with children. Santa Teresita and San Bernardo concentrate a huge choice of accommodation, food, shops and entertainment, with pedestrian streets that in summer pulse day and night. The Santa Teresita fishing pier is a classic, and the towns are close enough together to move easily between them. It's a popular and affordable option, at a reasonable distance from Buenos Aires.
This guide covers the essentials of Santa Teresita and San Bernardo with a practical eye: the beaches, the pedestrian streets and the shopping scene, the pier and the fishing, the outdoor activities, the nearby attractions of the Partido de la Costa, where to eat and stay, and how to get there. They're ideal for a lively, affordable family holiday on the Argentine coast.
Santa Teresita and San Bernardo are part of the Partido de la Costa, created in 1978 when it split from the district of General Lavalle, in the Tuyú region. They developed through the 20th century as family beach resorts on the dunes and shoreline of the northern Buenos Aires coast, becoming two of the busiest and best-equipped centers in the district.

Origins, formation and what the sources say.
In January, the pedestrian streets of Santa Teresita and San Bernardo pulse with hundreds of thousands of visitors; barely a century ago there was nothing here but dunes, wind and cattle from the estancias of the Tuyú. That's the name — 'Tuyú', a word of Guaraní origin usually translated as 'mud' or 'muddy' — of the northern end of the Atlantic coast of Buenos Aires province, a strip of dunes, beaches and wetlands that for a long time belonged to the large estancias of the sprawling district of General Lavalle, tied to cattle raising and to the marshes of the Bahía de Samborombón.
As beach tourism spread in Argentina through the 20th century, resort after resort sprang up along this coast, from San Clemente del Tuyú in the north to Mar de Ajó in the south. Santa Teresita and San Bernardo were among those that grew the most, developing as family holiday towns on the dunes.
The striking growth in population and tourism along this line of resorts led, in 1978, to the creation of the Partido de la Costa, which split from General Lavalle to administer this group of towns independently. So what had been land of estancias and dunes became one of the most popular and affordable holiday areas in the country.
The tourism development of Santa Teresita and San Bernardo followed the pattern of the holiday towns of the Buenos Aires coast: the parceling of coastal land, gradual urbanization over the dunes and the building of houses, hotels, cabins, campsites and shops aimed at middle-class family tourism. Their relative closeness to Buenos Aires and their affordable prices made them very popular.
Unlike the wooded, quiet resorts further south along the coast, Santa Teresita and, above all, San Bernardo developed a lively, commercial profile, with pedestrian streets packed with shops, food and entertainment, and — in San Bernardo's case — a nightlife that particularly draws young people. Santa Teresita added its classic fishing pier as one of its icons.
Within the Partido de la Costa, both resorts established themselves as two of the busiest and best-equipped centers, part of the continuous run of towns along the Tuyú coast. The proximity of attractions such as San Clemente del Tuyú, with the Mundo Marino park, and the Bahía de Samborombón rounded out the profile of an area built for mass, affordable family holidays, still one of Argentina's great beach destinations.
Like many resorts on the Buenos Aires Atlantic coast, Santa Teresita and San Bernardo were born of the initiative of land developers and property entrepreneurs who, in the first decades of the 20th century, saw in the coastal dunes the chance to create holiday towns. Santa Teresita began to take shape as a resort around the 1940s and 1950s, with its streets laid out, the dunes fixed by planting trees and plots sold to middle-class families looking for their own place by the sea. San Bernardo followed a similar path, taking hold as a resort town around the same time.
The first holidaymakers arrived on still rough roads and stayed in simple guesthouses, huts and the first holiday homes. Better roads and, above all, long-distance bus services from Buenos Aires were decisive in opening things up: the coastal summer holiday stopped being a privilege of the few and became a popular Argentine tradition. The building of the Santa Teresita fishing pier soon became one of the symbols of the place, and over the years turned into the obligatory landmark for anyone wanting to photograph sunrise over the Atlantic or simply walk out to sea on the concrete structure.
That spirit of a family town, raised plot by plot on the sand by pioneers and holidaymakers, still marks the identity of these resorts. Over the decades, urban development gained ground on the dunes, services multiplied and the towns grew, but they kept their profile as an affordable destination for mass summer holidays, true to their mid-20th-century origins.
A chapter of its own, tied to this same coastal strip, is the Faro Punta Médanos, at the southern end of the Partido de la Costa, on the RP 11 between Mar de Ajó and Pinamar. Made in Paris by the firm Barbier, Bernard & Turenne, shipped over in pieces and put into service in 1893, it stands 59 meters tall — one of the tallest lighthouses in Argentina — and holds 298 spiral steps inside. Brought by law into the system of Centenary Lighthouses as a historic monument, it still stands surrounded by a vast field of live dunes shaped by wind and sea with no development in sight. That untouched landscape contrasts with the bustle of the resorts and explains why 4x4 trips across the dunes became one of the most sought-after outings for people holidaying in Santa Teresita and San Bernardo who want to see the other face of this coast, the one from before the land was parceled out.
Today, Santa Teresita and San Bernardo are among the busiest beach destinations in Argentina, taking in hundreds of thousands of visitors every summer, above all from Buenos Aires and the center of the country. The Partido de la Costa, which they belong to alongside San Clemente del Tuyú, Mar del Tuyú, Mar de Ajó and other resorts, bases much of its economy on seasonal tourism, with a sharp peak in January and February and a season running from December to Easter.
In recent decades, the resorts have sought to diversify what they offer in order to sustain activity and attract visitors outside high season: long weekends, fishing tourism, cultural and nature proposals, and the proximity of attractions such as Mundo Marino, the Termas Marinas and the Bahía de Samborombón reserves. San Bernardo strengthened its young, nightlife-driven profile, while Santa Teresita reinforced its family character and its pier as an icon.
Today's challenges combine tourism and the environment: managing the heavy impact of mass tourism, looking after the beaches and the dunes, improving infrastructure and spreading the economy beyond the season. Even so, the essential appeal is intact: wide, safe beaches, affordable prices, an intense shopping scene and the short trip from Buenos Aires make Santa Teresita and San Bernardo two classics of the popular Argentine summer, drawing the crowds back season after season.
