Les Eclaireurs Lighthouse on the Beagle Channel, Ushuaia, with snowy mountains

Beagle Channel

Sail the waters that Darwin explored. Sea lions, penguins, cormorants and the lighthouse at the end of the world.

Last updated: April 2026

The Beagle Channel cruise is, alongside Tierra del Fuego National Park, the essential experience of any trip to Ushuaia. This 240 km channel separates the main island of Tierra del Fuego (Argentina) from the islands to the south, including Isla Navarino (Chile), and connects the Atlantic and Pacific oceans along one of the most southerly navigable waterways on Earth. It was here, in these cold and windy waters, that Charles Darwin sailed in 1833 aboard HMS Beagle — the ship that gives the channel its name — during the voyage that transformed our understanding of life on Earth.

The cruise from Ushuaia visits the channel's islands in heated catamarans with outdoor decks, passing colonies of sea lions, extraordinary numbers of seabirds and the iconic Les Eclaireurs Lighthouse, which has become Ushuaia's photographic symbol. Extended versions include Isla Martillo — where thousands of Magellanic and Gentoo penguins nest between October and March — and Estancia Harberton, the oldest settlement in Tierra del Fuego.

Isla de los Lobos: the first stop

About 30 minutes from Ushuaia's port, Isla de los Lobos hosts one of the Beagle Channel's largest colonies of South American sea lions and fur seals. Hundreds of these animals rest on the rocks, bark and dive into the water with a grace that contrasts with their clumsiness on land. The boat approaches within metres for detailed observation and photography.

Bird Island: the avian spectacle

Bird Island (Isla de los Pajaros) hosts enormous colonies of imperial cormorants and Magellanic cormorants covering the vertical cliffs with their black-and-white nests. Thousands of cormorants, kelp gulls, skuas, petrels and oystercatchers create a constant commotion.

Les Eclaireurs Lighthouse: the "end of the world" lighthouse

The highlight for most travellers is passing the Les Eclaireurs Lighthouse, a small red-and-white lighthouse built in 1920 on a rocky islet. It is often mistakenly called "the end of the world lighthouse" — the true lighthouse from Jules Verne's novel is on Isla de los Estados, far to the east. But the confusion has become part of the mystique: Les Eclaireurs is today Argentina's most photographed lighthouse.

Isla Martillo: the penguin colony

Isla Martillo, opposite Estancia Harberton about 70 km east of Ushuaia, is home to the Beagle Channel's only tourist-accessible penguin colony. Between October and March, thousands of Magellanic penguins arrive to nest and breed. Since 2010, a small colony of Gentoo penguins has also established itself. Groups are limited to 20 people per landing, providing an intimate encounter. Costs USD 80-100.

Estancia Harberton: living history at the end of the world

Estancia Harberton is Tierra del Fuego's oldest settlement, founded in 1886 by Anglican missionary Thomas Bridges. The visit includes historic gardens, original buildings and the Acatushun Museum of Southern Marine Birds and Mammals with over 2,800 skeletons. The estancia also serves lunch with local products.

When to sail the Beagle Channel

  • Summer (December-February): Best overall. Long days (up to 17 hours of light), peak wildlife activity, penguins on Isla Martillo, temperatures 5-15C.
  • Autumn (March-May): Penguins start migrating (March still has some). Fewer tourists, lower prices. Spectacular autumn colours.
  • Winter (June-August): Short days (7 hours of light), -5 to 3C. No penguins. Sea lions and cormorants remain. Spectacular snowy landscapes.
  • Spring (September-November): Penguins arrive in October. Good prices. November is excellent for combining penguins with reasonable rates.
Local tip: Dress warmly in layers even in summer. On the boat it is cold, especially on the outer deck. Waterproof windproof jacket, fleece, gloves, scarf and beanie are essential. If prone to seasickness, take Dramamine 30 minutes before boarding. Binoculars greatly enhance wildlife viewing.
