Martillo Island: Boat Trip to the Penguin Colony & Beagle Channel

Martillo Island is the main event, but the Beagle Channel crossing is much of the experience. You cruise past Ushuaia, snow-edged mountains, sea lions, cormorants, a famous lighthouse, and distant Chilean shores before reaching the penguin colony. The scenery keeps the long ride worthwhile.

I like two things here: the boat gets close enough for useful wildlife views, and the route gives you a broad look at Tierra del Fuego rather than a quick ride straight to one island. The main caution is simple: you stay on the catamaran. If walking among penguins is your goal, this is the wrong excursion.

• Martillo Island from the water: Watch Magellanic penguins during the summer nesting season without going ashore.
• A full Beagle Channel circuit: The route includes bird islands, sea lions, mountain views, estancias, and the Les Eclaireurs Lighthouse.
• Wildlife variety: Look for Magellanic and Imperial cormorants, sea lions, penguins, and several Tierra del Fuego bird species.
• A five-hour commitment: The trip can take about two and a half hours to reach Martillo Island, so the return ride matters.
• A large shared boat: The catamaran can carry up to 120 people, which affects photo spots and how easily you hear commentary.
• Weather matters: Wind can make the return rough, and poor conditions may cancel or shorten the trip.

Reaching Martillo Island by catamaran

This outing costs about $177 per person and lasts roughly five hours. That makes it a serious half-day purchase, not a quick add-on between other Ushuaia activities.

The value depends on what you want. If you want a single outing that combines the Beagle Channel, marine birds, sea lions, a lighthouse, mountain views, and penguins, the price covers a lot of ground. If your only aim is to stand beside penguins, the tour will feel expensive because it does not include an island walk.

The boat leaves from the Canoeros box office at Ushuaia’s tourist port, at Av. Prefectura Naval Argentina 470. Arrive 30 minutes before departure so you can collect boarding instructions and get into position without a last-minute scramble.

The catamaran is described as clean and well maintained, with indoor seating and an onboard cafeteria. Food and drinks are not included, and outside food is not allowed for sanitary reasons. The bar has limited choices, so do not count on a full meal. A sandwich and drink may be enough for the crossing, but eat beforehand if you need something substantial.

From Ushuaia to the open Beagle Channel

The first part of the trip gives you a fine introduction to Ushuaia from the water. As the boat pulls away, you see the city backed by the mountains, including Olivia and Cinco Hermanos. You also pass landmarks connected with the city’s identity, such as the Maritime Museum and the End of the World.

The views change as the boat moves away from shore. Estancia Fique, Estancia Tunnel, the Encajonado River, and other coastal features appear along the route. This is a good reason to spend time outside, even if the wind is sharp. The enclosed cabin offers shelter, but the best photographs usually come from the deck.

You should dress for cold, wet, and windy conditions, even in summer. The tour operates in all weather conditions unless conditions are poor enough to prevent the full navigation. A sunny departure does not guarantee calm water later in the day.

The long ride also has a practical consequence: if you dislike boat travel, five hours can feel repetitive. One passenger found the return trip too long, while another reported rough seas that caused extensive seasickness. Bring whatever personal remedy you normally use, and keep your expectations realistic. This is a boat excursion first, a penguin visit second.

Bird Island and the sea lions of Bridges Archipelago

The boat circles the Isla de los Pájaros and Isla de los Lobos, both part of the Bridges archipelago. The bird island is home to species associated with Tierra del Fuego, including skuas, Black-browed Albatrosses, steamer ducks, cauquenes, and both Cook and Gray gulls.

At Isla de los Lobos, you look for sea lions resting on the rocks. The boat approaches close enough for clear views, although wildlife is never posed for the camera. Your best chance of a good photograph comes from being ready before the boat reaches the island, rather than waiting until the last moment.

Large boats create a small battle for sightlines. People naturally gather at the front and along the sides, and those spots can fill quickly. Move around when the crew allows it, but do not expect every passenger to have an unobstructed view at every stop. A camera with a strong zoom lens is useful, especially for birds and animals on rocks.

This part of the route is valuable because it keeps the trip from being only a penguin transfer. Even if penguin activity is limited on a particular day, you still have several chances to see marine life and birds.

Les Eclaireurs Lighthouse and the SS Monte Cervantes

The catamaran then heads toward the center of the Beagle Channel and reaches Les Eclaireurs Lighthouse. The red-and-white lighthouse has become one of Ushuaia’s best-known images, but the stop is more than a photo opportunity.

Nearby rocks support Imperial Cormorants and Rocky Cormorants. Their upright posture and dark, wet feathers can make them look like small penguins from a distance, so listen carefully to the guide’s explanations. The boat’s position gives you a useful view of the colonies without requiring a landing.

The commentary also covers the SS Monte Cervantes, a passenger ship that sank in 1930. This brief piece of maritime history gives the lighthouse stop more meaning than a simple picture stop.

Sound can be a problem here. With up to 120 people aboard, engines, wind, and conversation may make the narration hard to follow from some areas of the boat. Sit near a speaker if you care most about the explanations, then move outside for photographs when the boat reaches the viewing point.

Puerto Almanza, Puerto Williams, and the approach to Martillo Island

After the lighthouse, the route continues east toward Martillo Island. Along the way, you see Puerto Almanza on the Argentine side and Puerto Williams Naval Base on the Chilean side. The view is a reminder that the Beagle Channel is both a scenic waterway and an international border region.

The mountains frame the channel as the catamaran moves east. The scenery is broad and quiet, with water, rocky shores, distant settlements, and high ground surrounding the route. The trip works best when you treat the crossing itself as part of the day, not merely as time spent getting to the penguins.

Some boats have spotted whales during this section, and the captain may turn back briefly if one is seen. That is a lucky extra, not something to expect. The guaranteed wildlife focus is the bird islands, sea lions, and the summer penguin colony.

Seeing the penguins without going ashore

At Martillo Island, the catamaran stops to observe Magellanic penguins nesting during the summer season. The boat comes close to shore, giving you time to watch and photograph the colony while the guide explains penguin biology and behavior.

The important detail is that this tour does not include walking on the island. You remain aboard the catamaran. Some promotional images and wording have caused confusion, so check this point before paying. The boat may provide a close view, but it is not the same as standing on a marked path among the birds.

Penguin numbers can vary. On one day, you may see many birds close to shore. On another, you might see only a small family group. Wildlife viewing always has that uncertainty, and the boat cannot make the animals appear in a particular place.

A zoom lens helps. From the boat, you can see penguins at close range, but a phone camera may produce small figures rather than detailed portraits. Keep your camera ready, since individual birds may appear briefly at the waterline or move behind others.

The boat-based format has a conservation advantage. You are not walking through nesting areas or approaching birds on foot. It also makes the excursion accessible to people who prefer not to hike on uneven ground. The tradeoff is less intimacy and more competition for the best viewing positions.

What the five-hour length really means

The stated duration is about five hours, and the trip can take around two and a half hours to reach Martillo Island. That leaves a substantial return journey after the penguin stop.

I would choose this tour when I want a broad day on the channel and have enough time to enjoy the ride. I would not choose it if I am impatient, prone to seasickness, or trying to fit several other activities into the same afternoon.

The return can be rough when wind and tide build. One reported outing turned back because of difficult conditions, while another continued but left many passengers seasick. Bring warm layers and stay aware that the water may not remain calm.

The guide’s narration is intended to be bilingual, but the quality and consistency of interpretation may vary. Most of the route includes commentary about the wildlife and geography. Still, one passenger had to request English interpretation near the end of the trip, while another felt that very little information was offered in English. If English commentary is essential to your decision, confirm the language arrangements before booking and sit where you can hear the microphone.

Group size, boarding, and the cruise passenger warning

The maximum group size is 120 people. That is not a small wildlife boat. You will have room to sit, but the outdoor viewing areas can become crowded when the lighthouse, sea lions, or penguins come into view.

Port organization can also take time. Allow the full 30 minutes before departure for check-in and boarding instructions. At the end, getting off the boat and through the port may involve lines.

This tour is not suitable for cruise passengers. The five-hour schedule, possible changes, and distance from the ship make it a poor match for a tight cruise timetable. Do not rely on a booking confirmation alone if you are arriving by cruise. Choose an excursion designed around your ship’s arrival and departure times.

Free cancellation is available when you cancel at least 24 hours before departure. Changes made within 24 hours are not accepted, and poor weather may lead to a different date or a full refund. If the boat reaches only part of the route because of weather, ask clearly what refund or replacement policy applies before accepting an alternative trip.

Who should book this Beagle Channel outing?

I would recommend it to you if you want to see several Ushuaia highlights in one organized trip, value a comfortable catamaran over a small boat, and are happy to watch penguins from the water.

It suits photographers with a zoom lens, families who prefer not to walk on rough island ground, and anyone who wants sea lions, birds, a lighthouse, mountains, and penguins in one half-day route. It also works well for visitors with a flexible schedule who can accept changing weather.

I would steer you elsewhere if walking among penguins is non-negotiable. I would also think twice if you dislike long boat rides, crowded viewing areas, uncertain wildlife sightings, or rough water.

Should you book the Martillo Island trip?

Book it if the full Beagle Channel experience appeals to you more than a single close-up wildlife encounter. The route is scenic, the penguin stop is real, and the mix of sea lions, cormorants, birds, mountains, and lighthouse gives you plenty to see.

Skip it if you expect to step onto Martillo Island, need guaranteed English commentary, or have only a narrow window before a cruise departure. At $177, the tour offers solid value only when you count the entire five-hour route. You are buying a long scenic navigation with penguins at the end, not a short walk with penguins.
