Navigating Patagonia's wilder fjords since 1965

A family-owned tour company from Puerto Natales that crosses the Última Esperanza fjord to the Balmaceda and Serrano glaciers in the heart of Bernardo O'Higgins National Park — a three-generation legacy of adventure in Chilean Patagonia.

Navigation to the Balmaceda and Serrano Glaciers from Puerto Natales

Turismo 21 de Mayo is a family-owned company based in Puerto Natales dedicated to Patagonian fjord navigation since 1965. We cross the Última Esperanza fjord in our own catamarans to the Balmaceda and Serrano glaciers, within Bernardo O'Higgins National Park, in Chilean Patagonia.

Our Estancia Perales is the heart of Turismo 21 de Mayo's Patagonian experience: horseback riding, trekking, e-biking and authentic regional cuisine on a family-run ranch operated by the Álvarez family since 1968, with accommodation available for special groups. Alongside our daily glacier navigations, we also operate Hostería Monte Balmaceda, your gateway to the northern sector of Torres del Paine National Park by sea — all under the same three-generation family operation.

Our Story

Half a century building navigation in Patagonia

Don Joaquín Álvarez Estefo and his brothers are third-generation descendants of true Patagonian pioneers. The story begins in 1904, when their grandparents, don Manuel Álvarez Ruiz and doña Isabel Coste, arrived in the Última Esperanza region. Decades later, that legacy became a sawmill on Península Roca, timber, handmade tools, and a conviction to share these waters with the world. This is the story told by the founder himself, Joaquín Álvarez Estefo.

"I always thought about working in tourism because here we have so many things to offer. I may not be around to see it, but I believe tourism here is the most important thing."

    The arrival of the pioneers

    Don Manuel Álvarez Ruiz and doña Isabel Coste, Joaquín's grandparents, arrive in the Última Esperanza region. From them descends the third generation of pioneers who still navigate these channels today.

    Mid-1960s

    The origins at Península Roca

    Don Joaquín, together with his brothers Nelson and Víctor Álvarez Estefo, sets up a sawmill at Península Roca. From that work with timber comes the idea of building their own vessel: the first 21 de Mayo.

    The first 21 de Mayo, built by hand

    At 26 years old, Joaquín and his brothers build the first 21 de Mayo entirely in wood: hewing the masts and even forging the bolts and nuts, which were nearly impossible to source in the region at the time.

  • Early 1970s

    The first tourists

    Before the new vessel was ready, the small launch Roca was already making trips to the glacier, though with limitations. Together with pioneer Nicolás Marcos Blanch, the first tourism routes to Balmaceda and Serrano glaciers are opened.

    The estancia and the first lodgings

    Joaquín and his brothers are awarded Estancia Perales, receiving it under a shared rental concession. There the family's first guesthouse is born.

  • A family that grows with the business

    Joaquín and doña Juana

    Don Joaquín marries doña Juana Rodríguez Teveni. Together they have four children, who throughout their lives have worked to grow the family business.

    From timber to naval steel

    The Alberto de Agostini is launched, built at the then-new Puerto Bories Shipyard: a naval-steel hull with timber interiors — a major technical leap for the family fleet.

    21 de Mayo III, capacity for 100 passengers

    Also at Puerto Bories, the 21 de Mayo III is built with a capacity of 100 passengers. The project is overseen by Ernesto Joaquín Álvarez Rodríguez, naval engineer and son of Joaquín and Juana — the next generation joins the fleet-building effort.

    The same family, a modern fleet

    Today the family remains at the helm, with state-of-the-art catamarans and barges for the region's logistical transport — serving both tourism and the development of Última Esperanza. Their own docks and workshops, and a mostly family crew, remain the hallmark they've always had.
