Beagle Channel History: From the Yamana to the Port of Ushuaia

Four layers sit on one stretch of sheltered water: the Yamana canoe people, the Royal Navy surveys that gave the channel its name, the missionaries and the first ranch on the shore, then the lighthouse era and the port.

Updated 29 October 2026

In shortBeagle Channel history runs in layers. The Yamana called the waterway Onashaga, hunters' channel, and left shell middens still visible on the Bridges Islands. HMS Beagle, launched in 1820, surveyed here from 1826 to 1830; FitzRoy was using the channel's name by September 1830, and Darwin sailed on the second voyage, 1831 to 1836. Thomas Bridges founded Harberton in 1886.

Beagle Channel history, in the order it happened

Ushuaia's municipal tourism board still gives the waterway its Yamana name, Onashaga, and describes it as lying between the Andes and the sea, valued for biodiversity, history and scenery. Everything that came afterwards, charts, missions, sheep, lights and docks, was laid on top of a shoreline that was already inhabited and already had a name.

The survey dates below come from naval records and Darwin's and FitzRoy's own writing. The lighthouse and the wreck are dated by tour itineraries, which give two different years for the light.

The Yamana people of the Beagle Channel and what they left on the shore

The Yamana worked this water by canoe. Their long occupation of the shoreline is readable today as shell middens: low mounds of discarded shell built up over generations at landing places on the islands just off Ushuaia.

That is the layer you can actually walk on. The short sailings that land on the Bridges group put you on a marked trail past these archaeological sites; one operator describes a guided walk of about 20 minutes at Puerto Karelo that passes Yamana middens and ends at a viewpoint, while a yacht itinerary on the same stretch calls the deposits on Isla Bridges the largest in the region. Keep to the marked trail as you walk past the mounds.

The population figure that survives from the contact period is a naval one: when Lasserre arrived in 1884, the Argentine Navy records the Anglican Mission at Ushuaia standing beside a Yamana community of about 350 people. Across the water, Puerto Williams holds the Museo Territorial Yagan Usi - Martin Gonzalez Calderon at Aragay esquina Gusinde, renamed and reopened on 10 January 2024, with ethnographic, historical and archaeological collections centred on Yagan culture.

The survey voyages that named the channel, and FitzRoy's whale-boats

The channel carries the name of a ship. HMS Beagle came off the slip at Woolwich Dockyard in 1820 as a 10-gun brig sloop and was later converted for survey work under Robert FitzRoy. Her first voyage, from 1826 to 1830, charted Patagonia and Tierra del Fuego, and this waterway was explored on that expedition. By the time FitzRoy wrote to Captain King on 12 September 1830 the name was already in use, which pins the naming to the first voyage, although who chose it is not recorded.

The Admiralty sent the ship back for the rest of the job. A memorandum of 11 November 1831 from Hydrographer Beaufort told the second expedition to complete the survey of the channel, and that second voyage, 1831 to 1836, carried Charles Darwin.

Darwin's own account dates the push into the channel to 19 January 1833, when three whale-boats and the yawl set out with twenty-eight men under FitzRoy. He described the channel as roughly 120 miles long, with an average breadth of about two miles. He also noted Ponsonby Sound branching off at right angles, the home of Jemmy Button's people, where FitzRoy had decided to resettle the Fuegians the ship had brought back.

Missionaries, Lasserre and how Ushuaia became a town

The Anglican mission at Ushuaia was already standing when the Argentine state arrived. In 1884 Commander Augusto Lasserre brought a six-ship expedition to Tierra del Fuego and Isla de los Estados and came ashore in Ushuaia Bay, where he met Reverend Thomas Bridges at the mission.

What Lasserre did next is why the Navy treats 1884 as the founding event of the city: he buoyed the navigation channels and put up the first public buildings, including the Subprefectura. Buoyed channels are the unglamorous beginning of the port you sail from now.

The administrative town followed quickly. The Antigua Casa de Gobierno went up between 1886 and 1890 and served as governor's residence, government house and later the provincial legislature; it is now an annex of the Museo del Fin del Mundo, at Maipu 465, with the main building at Maipu 173. The museum opens Monday to Friday 9:00 to 18:00 and Saturday 13:00 to 19:00, closed Sundays and public holidays, and one ticket covers both buildings.

Harberton, the lighthouse and the shipwreck

Thomas Bridges left the mission and in 1886 founded Estancia Harberton, about 90 km east of Ushuaia at Ruta J Km 43, facing Isla Martillo. It is still worked by the fifth and sixth generations of the family, has the Museo Acatushun on site with guided visits, and opens to the public from 11 October to March, 12:00 to 19:00, closed on Tuesdays and also on 25 December and 1 January. Walking into the 1886 ranch means paying the estancia's own admission, which sits outside whatever tour brought you there.

The lighthouse era belongs to the short route east of town. Les Eclaireurs stands about 20 km from Ushuaia and is the turning point of the short sailings; tour itineraries date it to 1919 or 1920, and the exact year is not settled. The wreck of the Monte Cervantes near the light is dated to 1930.

Expect the lighthouse to be confused with the other one. Two separate structures get collapsed into a single story, and the municipal tourism page says so plainly: the Faro del Fin del Mundo belongs to Isla de los Estados, more than 200 km away and realistically beyond a day trip, so it is not what passes the catamaran window. The version of it you can stand next to in town is a replica, kept inside the former prison that houses the Museo Maritimo at Yaganes and Gobernador Paz, alongside the Antarctic Museum, open daily 10:00 to 20:00 with last admission at 19:30.

The port kept growing after the lights went in. Channel excursions now leave from the port area on Avenida Prefectura Naval Argentina all year, cruise ships come mainly in summer, and Antarctic departures run from November to April, with about 90% of Antarctic journeys starting with a stop in Ushuaia, some 1,000 km from the continent.

Which sailing shows you these layers: the historic landing or the eastern estancia leg

Decide this by which layer you want underfoot. The short route east out of the tourist port covers the Yamana middens and the lighthouse era in one half day: sea lion and cormorant islets, the turn at Les Eclaireurs about 20 km out, and a walk ashore on the Bridges group where the interpretive trail runs past the archaeological sites. The sailing that strings those layers together is the Beagle Channel Navigation with Minitrekking: 4 hours, from US$100, rated 4.8 ★ (724 reviews). Its guided walk ashore is the whole point if history is your reason for going out.

The 3.5-hour yacht sailing, from US$110 and rated 4.9 ★ (11 reviews, so read it as a small sample), works the same stretch of water on a small boat with coffee or tea on board, and makes a short stop on Isla Bridges when conditions allow; a harbour tax of about US$3 is not included. Choose it for photography and quiet rather than for a long walk ashore.

The eastern estancia leg is a different commitment. Harberton and Isla Martillo sit about 90 km out, which means a long day by water or a road transfer along National Route 3 and Provincial Route J, and the estancia only opens to the public from 11 October to March, closed Tuesdays. If your trip falls outside that window, or you have one spare half day, the short island landing is the better use of it. One operator also notes the island landing can be cancelled for safety, for example with ice or frost in winter, so plan the sailing early in your stay and keep a spare day.

Two companion pages on this site go deeper into the layers named here: the lighthouse page for Les Eclaireurs and the confusion with the Faro del Fin del Mundo, and the estancia page for Harberton and the Museo Acatushun.

Questions people ask

Who named the Beagle Channel, and when?

The channel takes its name from HMS Beagle, and the name was already in use at the end of the first survey voyage: FitzRoy writes it in a letter to Captain King dated 12 September 1830. Which officer chose it, and on what date, is not recorded, so treat any precise naming story with caution. The first voyage ran from 1826 to 1830 and covered Patagonia and Tierra del Fuego.

Was Darwin on the voyage that discovered the channel?

No. The channel was explored on the first voyage, 1826 to 1830, before Darwin was involved. He sailed on the second voyage, 1831 to 1836, which the Admiralty had instructed on 11 November 1831 to complete the survey. Darwin's part in the channel itself begins on 19 January 1833, when he records a party of twenty-eight setting out in three whale-boats and the yawl.

Can you see the Yamana shell middens from the boat?

Not usefully from the water. The middens are low mounds at old landing places, and you see them by going ashore on the Bridges group, where a guided interpretive trail runs past the sites. That means choosing a sailing with a landing: the 4-hour Navigation with Minitrekking includes a guided walk on the island.

Is the Bridges family still connected to the channel?

Yes. Thomas Bridges, the Anglican missionary Lasserre met at Ushuaia in 1884, founded Estancia Harberton in 1886, and the estancia is still run by the fifth and sixth generations of the family. It sits about 90 km east of Ushuaia at Ruta J Km 43, opposite Isla Martillo, with the Museo Acatushun on site and guided visits, open to the public 11 October to March, 12:00 to 19:00, closed Tuesdays.

Where can you follow this history on land in Ushuaia?

Two museums carry most of it. The Museo del Fin del Mundo occupies the former Banco Nacion building at Maipu 173 plus the Antigua Casa de Gobierno annex at Maipu 465, built between 1886 and 1890, open Monday to Friday 9:00 to 18:00 and Saturday 13:00 to 19:00 on one ticket. The Museo Maritimo y del Presidio at Yaganes and Gobernador Paz opens daily 10:00 to 20:00, last admission 19:30, and holds the replica of the Faro del Fin del Mundo.
