Catamaran Tour through the Beagle Channel and Penguins in Isla Martillo

The penguins are the headline, but the full appeal is the trip through the Beagle Channel, with sea lions, nesting seabirds, the Les Eclaireurs Lighthouse, and distant views toward Chile. At Isla Martillo, the catamaran moves close to shore so you can watch Magellanic and Gentoo penguins walk, swim, and gather on the beach.

I like the captain’s careful positioning, which gives people on both sides a chance to see the animals. I also like the warm catamaran, bilingual commentary, onboard café, and restroom, all useful on a cold five-hour outing.

The main catch is simple: you do not get off the boat at Isla Martillo or the other islands. The port check-in can also be confusing, and the outside decks get very cold and windy.

Key points to know before you book

• Penguins stay on Isla Martillo: You view the colony from the catamaran, usually only a few meters from shore, with no beach landing.
• Several wildlife stops are boat-based: Isla de los Pájaros, Isla de los Lobos, Gable Island, and the lighthouse are viewed from the water.
• The catamaran moves for better views: The captain turns and repositions the boat so different sections can see the animals.
• Bring serious cold-weather clothing: The outdoor deck is the best place for photos, but wind on the channel can be fierce.
• Allow extra time at the port: You may need to find the operator’s kiosk, collect a boarding ticket, and then join the port control line.
• The $240 price buys a full half-day outing: It is worthwhile if you value close wildlife views and scenery, but less so if you expect to walk among penguins.

Why the Beagle Channel is worth your morning

From Ushuaia’s tourist port, the catamaran heads into the Beagle Channel, the waterway that separates southern Tierra del Fuego from the islands and coastlines farther south. You get a strong sense of place here. This is not simply a ride to a penguin colony. The water, low hills, distant settlements, seabirds, and shifting weather make the journey part of the experience.

The route passes the Bridges archipelago, a group of islands named for the Bridges family, whose work in the region is tied to the early Anglican mission at Ushuaia. You also see the fishing village of Puerto Almanza and, across the channel, the Chilean side of Tierra del Fuego.

The guide provides commentary in Spanish and English. Several people found the explanations helpful for both wildlife and local history, though the amount of English information can vary. If you do not speak Spanish, sit where you can hear the guide clearly and pay attention early in the trip, when the windows are clean and the boat is less crowded around the viewing areas.

The catamaran is a large vessel with indoor seating, outdoor decks, heating, restrooms, and a café. That matters in Ushuaia. Even on a clear day, the wind can turn a pleasant deck stop into a cold one within minutes.

The first wildlife stop: Isla de los Pájaros

Isla de los Pájaros, or Bird Island, is part of the Bridges archipelago. The boat approaches slowly so you can look over the rocks and shoreline for seabirds.

The birdlife can include skuas, Black-browed Albatross, steamer ducks, upland geese, kelp gulls, and grey gulls. You will not be walking through a reserve or following a marked trail. Instead, the captain brings the vessel close enough for you to scan the nesting areas from the deck and windows.

This is where binoculars help. You can still see the birds without them, but a small pair makes it easier to pick out species and watch behavior. Keep your camera ready, but do not spend the entire stop looking through a screen. The boat may turn quickly, and the best view can shift from one side to the other.

The word stop can be misleading here. The catamaran pauses or circles near the island, but you do not disembark. There is no admission gate or walking visit.

Sea lions at Isla de los Lobos

Next comes Isla de los Lobos, where the main attraction is the colony of South American sea lions. You may see both one-haired and two-haired sea lions resting on the rocks or slipping into the water.

This is one of the more entertaining parts of the trip. Sea lions are active, noisy animals, and their movements are easy to follow from the boat. The vessel stays near the rocks long enough for the captain to give several sections of the catamaran a useful view.

The smell can be strong. That is part of any close wildlife encounter, especially when a large colony is gathered on a small rocky island. If you are sensitive to odors, step back inside for a moment, then return to the deck when the boat changes position.

The captain’s handling is important here. The catamaran does not simply stop and leave passengers to fight for one fixed view. It turns to show the animals from different angles, though the outside decks can still feel crowded when everyone reaches for a camera at once.

Les Eclaireurs Lighthouse and the SS Monte Cervantes

The familiar red-and-white Les Eclaireurs Lighthouse is one of Ushuaia’s most photographed sights. It is often called the Lighthouse at the End of the World, although that name properly belongs to another lighthouse farther east on Isla de los Estados.

The catamaran pauses near the lighthouse for roughly 20 minutes. This is the classic photo stop, with the tower against the channel and mountains. You can also look for Imperial and Rock Cormorants on the nearby rocks.

The guide also covers the SS Monte Cervantes, a German passenger ship that sank in the Beagle Channel in the 1930s. The wreck became part of Ushuaia’s maritime story, and the lighthouse stop gives the history some useful context.

If you want a clean photo through the windows, take it early. As the trip continues, sea spray and water spots can build up on the glass. The best shots usually come from the outside deck, but you will need to accept the cold and wind.

Puerto Almanza, Chile, and Gable Island

The route continues through the Bridges archipelago and past Puerto Almanza, a small fishing village on the Argentine side. You also get views across the channel toward Chile.

These passages are quieter than the wildlife stops, but they help you understand the geography. Ushuaia sits at the end of a long road, yet the channel connects it to a much wider maritime world. The border is not marked by a dramatic wall or checkpoint. It is water, islands, and distant shores.

Gable Island is another notable point on the route. It was once home to the Yámana, the Indigenous people who lived around the channels of Tierra del Fuego. The guide uses the island and surrounding waters to discuss the region’s earlier inhabitants and the changes brought by European settlement.

Again, this is a sightseeing passage rather than a walking stop. You remain aboard the catamaran throughout.

Isla Martillo: penguins from the catamaran

Isla Martillo is the reason most people book this excursion. The boat spends about 40 minutes near the island, where a colony of more than 6,000 Magellanic and Gentoo penguins gathers during the season.

You may see penguins standing in groups, waddling between the water and their nesting areas, or swimming close to the boat. Magellanic penguins are the main sight, while Gentoo penguins add variety. King penguins are possible but not guaranteed.

The catamaran approaches the beach closely, sometimes within roughly four or five meters of the penguins. This creates excellent views without sending people onto the nesting grounds. The boat’s position changes during the stop so passengers on different sides have a chance to see the colony.

This is also the point where expectations matter most. There is no landing on Isla Martillo. You will not walk on the beach, stand among penguins, or follow them along a trail. If you want a shore-based penguin visit, this is the wrong product. If you are happy to watch wild birds from a boat and prefer a lower-impact approach, the arrangement makes good sense.

The viewing system can feel orderly or crowded depending on the departure. People move around the boat to make room for others, and the crew may direct passengers toward different viewing areas. Some departures have handled this fairly well. On others, photographers and passengers seeking the best angles have made the front sections feel cramped.

The optional photography service is another consideration. Professional photographers work aboard the boat, and some passengers have felt that paid photo customers received preferred positions. You can still take your own pictures, but arrive early, choose a good place, and be prepared to move when the crew rotates viewing areas.

Seats, decks, café, and motion on the water

The catamaran is comfortable by excursion-boat standards. Inside, you have warmth, seating, a restroom, and café service. Food and drinks are available if you get hungry, and a hot drink can be welcome after time outside.

The indoor seats are not all equal. Window seats give you a clear view without dealing with the wind, but getting in and out can disturb people beside you. Arrive early if you want a choice. Upper-level seating can provide a broad view, while lower sections may put you closer to the water and the penguin stop.

The outdoor deck is where I would spend at least part of the trip. The views are better, and photos are easier without glass between you and the channel. Dress for winter even if Ushuaia looks sunny when you leave. A warm coat, hat, gloves, and layers are practical, not excessive.

The boat is fairly stable, but the channel can still be rough. On calm days, the ride feels gentle. With strong wind, the catamaran can roll enough to make some passengers seasick. One departure was postponed because of unsafe wind and operated later when conditions improved. That is a sensible safety decision, but keep your schedule flexible.

If you are prone to motion sickness, sit near the center of the vessel, look toward the horizon, and avoid spending the entire ride at the front or far sides. The tour operator can cancel or reschedule when weather makes navigation unsafe.

The port check-in needs more attention

The tour begins at the tourist port on Avenida Prefectura Naval Argentina 470. The activity returns to the same general meeting point.

The confusing part is the boarding process. Your booking confirmation may not function as the final boarding ticket. You may need to find the operator’s kiosk, show the reservation or PDF, receive a printed ticket, and then walk to passenger control or the correct boarding area.

The port can be crowded, especially when cruise passengers are present. Give yourself extra time and do not assume that the first booth or queue you see is yours. Look for the catamaran operator’s booth, often described as a light green kiosk, and ask staff to confirm both ticket collection and the boarding gate.

This is the one part of the outing that has repeatedly caused avoidable stress. Once the boat leaves, the day generally runs according to plan. Before departure, clear instructions and an early arrival make a real difference.

Is $240 a fair price?

At $240 per person, this is not a cheap boat ride. You are paying for a five to six-hour excursion, a heated vessel, crew, bilingual guidance, port fees, onboard facilities, and close views of several wildlife sites.

The value depends on what you want. If your priority is seeing penguins, sea lions, seabirds, and the Beagle Channel in one half-day, the tour packs a lot into a single outing. You also avoid arranging several separate transfers or boat trips.

The price is harder to justify if you expect a small group or a personal wildlife encounter. The vessel can carry up to 160 people, so this is a shared cruise, not an intimate expedition. You may find crowded viewing areas, especially at Isla Martillo.

I would compare it with the cost of other penguin excursions in Ushuaia, but I would also read the description carefully. The most important question is not only how much does it cost? It is does the price match a boat-based viewing experience?

Who should book this Ushuaia boat trip?

I would choose this tour if you have one free half-day in Ushuaia and want to combine scenery, wildlife, and local history. It suits families, couples, solo visitors, and anyone who prefers a comfortable vessel with indoor facilities.

It is also a good choice for photographers who can work patiently from a shared boat. Bring a long lens if you have one, but do not expect every penguin to face your camera at the perfect moment.

I would think twice if you need to walk on an island, dislike crowded excursions, or become seasick easily. The trip can be windy and rough, and the most popular viewing points fill quickly.

The experience also works best in good weather. Sunlight makes the channel and animals easier to see, while calm water makes the ride more pleasant. Poor weather can cancel the departure or force a change in timing.

Should you book it?

Book it if you want close views of penguins without leaving the catamaran, and if the Beagle Channel itself interests you as much as Isla Martillo. The lighthouse, sea lions, seabirds, Puerto Almanza, Gable Island, and Chilean views give the outing more substance than a simple ride to a colony.

Skip it if your dream is to walk among penguins or take a quiet, small-group boat. The $240 price is reasonable for a full wildlife cruise with good weather and fair viewing rotation, but it feels high if you arrive expecting island access.

My practical advice is to arrive early, confirm the kiosk and boarding process, dress warmer than you think necessary, and sit where you can move between indoor and outdoor viewing areas. With those expectations in place, this is one of Ushuaia’s strongest half-day outings.
