What the Beagle Channel is
The channel is named after the HMS Beagle, the ship on which Darwin made his famous voyage. The strait separates the Argentine and Chilean parts of Tierra del Fuego and connects the Pacific and Atlantic Oceans.
Length — about 240 km, width — 3–10 km. Deep enough for large cruise ships to pass through.
What you can see
Les Éclaireurs Lighthouse — a red-and-white lighthouse on a rocky islet, built in 1920. One of the main landmarks of Ushuaia. Often (incorrectly) called the "lighthouse at the end of the world" — the real Faro del Fin del Mundo (San Juan de Salvamento lighthouse) is on Isla de los Estados, 300 km to the east.
Sea Lion Islands (Lobos del Mar) — small rocks where southern sea lions live year-round. You can get up close.
Cormorant and penguin colonies — imperial cormorants nest on the distant rocks. In season (October–March) you can see Magellanic penguins.
The Chilean side — when visibility is good, the mountain ridge of Chilean territory opens up across the water.
How to pick the excursion
Classic boat (catamaran) — 3–4 hours, lighthouse + sea lions + cormorants. Works for everyone, including kids and seniors. Departs from Ushuaia port.
Kayaking — 3–4 hours by kayak along the shore. No experience required — the instructor teaches right before launch. More intense, but closer to the water and wildlife.
Penguins + Harberton — full day (10 hours). Car + boat to Martillo Island with a walk among penguins. Best option if you want the full experience.
When to go
The Beagle Channel is open for excursions year-round. In summer (December–February) the long daylight up to 17–18 hours — a joy for photography. In winter the channel is mirror-calm, less wind. Penguin season — October–March.
Frequently asked questions
Do people get seasick on the catamaran? The channel is sheltered by mountains, strong swell is rare. If you're prone to motion sickness, take a pill.
