Bahía Bustamante is a former seaweed-harvesting village and today a tourism estancia on the San Jorge Gulf coast, in southeastern Chubut, inside the setting of the Patagonia Austral Coastal Marine Interjurisdictional Park. It's one of the most singular and untouched corners of the Patagonian coast, famous for its marine wildlife, its isolation and its history tied to harvesting seaweed.
Founded in the mid-20th century to exploit the seaweed of the gulf (a source of substances used in industry), the village was turned into a low-impact, exclusive nature tourism destination. It offers unspoiled coastline, colonies of seabirds and sea lions, penguin rookeries, petrified forest, steppe and an experience of absolute quiet, far from everything.
This guide covers the essentials: the marine wildlife and the penguin rookeries, the coastal and steppe landscapes, the seaweed history of the place, accommodation at the estancia (the only option), how to get there (it's very remote) and practical advice on seasons, bookings and self-sufficiency.
Bahía Bustamante was founded in 1953 by the businessman Lorenzo Soriano to exploit the seaweed of the San Jorge Gulf, used as industrial raw material (agar and other gels are extracted from it). It grew into a seaweed village with houses, a school and services. As the activity declined, his descendants turned it into a nature tourism estancia, today internationally known for its unspoiled coast and its wildlife. The full story is on our history page.

Origins, formation and what the sources say.
Bahía Bustamante has one of the most singular origins in all of Patagonia: it was born of seaweed. In the mid-20th century, a businessman spotted the potential of the great mounds of seaweed the sea deposited along the shores of the San Jorge Gulf. From that seaweed you could extract substances — certain colloids and derivatives — of industrial value, used in food, cosmetics and other products.
To exploit that resource, a seaweed village was founded on this remote stretch of the Chubut coast. Dozens of families settled there to harvest, dry and process the seaweed, bringing to life a town in the middle of nowhere: with houses, a school, a chapel and services, a self-sufficient community that depended entirely on the seaweed trade. In its day it was a prosperous, pioneering venture, one of the country's main seaweed producers.
That human history, so unusual, defines the character of the place. Bahía Bustamante isn't a town of ranching pioneers or a military fort, but a community that grew out of one specific marine resource, in an isolated corner of the Patagonian coast. The houses and facilities of that era, today partly preserved and restored, are testimony to that unique seaweed epic.
The man behind that epic was Lorenzo Soriano, a Spanish immigrant who came to Patagonia in the early 1950s looking for seaweed to produce a very valuable colloid: agar-agar, a polysaccharide extracted from certain seaweeds and widely used in food, cosmetics, pharmacy and microbiology. In 1953 he established the village of Bahía Bustamante and founded the seaweed-gathering operation known as Algamar.
In 1956, on the Chubut coast, Argentina's first production of agar-agar was achieved, a pioneering industrial milestone. The company, later formalized as Soriano S.A. and with a plant opened in 1967 in Gaiman, grew markedly between 1972 and 1976 until it became one of the world's leading agar-agar factories. The seaweed village came to have some 600 inhabitants, with houses, a school, a chapel and all the services of a self-sufficient community built on a single resource: the seaweed of the San Jorge Gulf.
For decades, generations of seaweed workers harvested, dried and processed the seaweed the sea left on the beaches, in hard and singular work. That prosperity, based on a product little known to the general public but essential to industry, made Bahía Bustamante a one-off in Patagonian economic history.
Over the decades, the seaweed trade lost the drive of its early years. Two major environmental spills in 1982 and the arrival of bottom trawling, which damaged the seaweed beds, hit the industry hard. Lorenzo Soriano's death in 1987 accelerated the decline, and the population — which had reached some 600 people — fell quickly. The factory finally closed in the early 2000s, and the seaweed village risked ending up as one more relic of the Patagonian past.
The extraordinary natural value of the setting, however, opened a new path. The unspoiled coast of the San Jorge Gulf, the penguin and sea lion colonies, the wealth of birdlife, the petrified forests and the steppe — all in an almost untouched setting of great beauty — offered enormous potential for nature tourism. The area also came under the scope of the Patagonia Austral Coastal Marine Interjurisdictional Park, which protects this shoreline.
So the descendants of the founding family turned Bahía Bustamante into a low-impact, exclusive nature tourism destination. The old houses of the seaweed village were restored to host a small number of visitors, who come in search of wildlife, untouched landscapes and total disconnection. Bahía Bustamante thus earned international recognition as one of Patagonia's best-kept secrets, where the history of seaweed and untouched nature go hand in hand.
The natural setting of Bahía Bustamante is the San Jorge Gulf, a wide inlet of the Argentine Sea between Chubut and Santa Cruz that is one of the most productive and biodiverse marine areas on the Patagonian coast. Its cold, nutrient-rich waters, its big tides and its mosaic of islands, rock shelves and coves support exceptional wildlife: penguins, cormorants, sea lions, gulls and countless seabirds that find shelter and food there.
To protect this heritage, the Patagonia Austral Coastal Marine Interjurisdictional Park was created in 2008, run jointly by the national government and the province of Chubut through the National Parks Administration. It was the first park of its kind in Argentina — marine and coastal — and covers a long stretch of the gulf's shoreline, including the area around Bahía Bustamante, with its islands and islets that are key for bird nesting.
That protected status is now an essential part of the identity of the place. The tourism Bahía Bustamante receives is conceived as low-impact and respectful of wildlife and ecosystems, in keeping with the history of a site that went from exploiting a natural resource to conserving and showing it. The steppe plateau inland, with its petrified forest and its land wildlife, completes a set of environments that make the area a genuine Patagonian natural sanctuary.
The rebirth of Bahía Bustamante as a tourist destination was neither instant nor easy. In the early 2000s, with the factory closed and most of the seaweed families gone to Comodoro Rivadavia or Trelew in search of work, the village was at serious risk of becoming one more ghost town on the Patagonian coast, like so many others left stranded by the closure of a single economic activity. It was Lorenzo Soriano's heirs who decided to bet on a different path: instead of abandoning the place, they restored the seaweed workers' old houses, respecting their original sheet-metal-and-wood architecture, and turned them into accommodation.
What began as a modest project — hosting a few travelers curious about the gulf's wildlife — became over the years one of the best-known nature lodges in Patagonia, with mentions in international travel publications and guests arriving from all over the world in search of disconnection and wildlife watching in its purest form. A more recent chapter in that story is the addition of a small vineyard by the sea, a singular experiment that takes advantage of the particular coastal microclimate of the San Jorge Gulf to grow vines at a geographical extreme where, until a few years ago, no one would have imagined seeing a planting of this kind. That vineyard, visible from the so-called Suite del Viñedo, is now part of the story the lodge's guides tell their guests: proof that at Bahía Bustamante reinvention never stopped, from industrial agar-agar to a glass of wine facing the sea.
Today the lodge combines a small number of houses — Casas de Mar, Lofts Marinos, the Suite del Viñedo and the simpler Casas de Estepa — with a philosophy of very low-impact tourism: few guests at a time, naturalist guides who know every corner of the coast and a strong emphasis on conserving the setting around the Patagonia Austral Coastal Marine Interjurisdictional Park. For anyone who makes it to this remote end of Chubut, Bahía Bustamante offers something increasingly scarce: a genuine human story — of seaweed, of agar-agar, of a village that almost disappeared and came back to life — woven into nature that remains practically untouched.
