Get to know the fauna of Martillo Island while sailing through the Beagle Channel.

If you are planning your trip to the end of the world in the spring season, visiting the penguin colony is one of the most interesting destinations on your list of excursions. In Ushuaia, among its many natural wonders, the fauna occupies a special place. One of the most fascinating destinations for nature and wildlife lovers is Isla Martillo, a true paradise where penguins are the protagonists. In this article we will explore the unique experience of visiting the island and getting up close and personal with these amazing birds.

Hammerhead Island: home of the penguins

Martillo Island, located in the heart of the Beagle Channel, about 85 kilometres southeast of Ushuaia, is home to one of the southernmost penguin colonies in the world. Here, during the warmer months, you can see a remarkable number of Magellanic and Gentoo penguins, two species that choose this place to nest and breed. A visit to the island is one of the most popular excursions for tourists seeking a close experience with the Antarctic fauna.

It is important for you to know that although the penguin colony is an activity that starts in October until March, you can sail through the Beagle Channel watching wildlife and visiting the Les Eclaireurs Lighthouse all year round. Even combined with other experiences, such as the Tierra del Fuego National Park.

Excursion to the penguin colony

Sailing to the penguin colony is one of the best ways to access Martillo Island. The tour starts from the port of Ushuaia, where visitors board comfortable boats that cross the Beagle Channel. Along the way, you can enjoy spectacular views of the surrounding landscape, such as the imposing Mount Olivia, the Bridges Islands, and the lighthouses of the region, all while navigating the cold, crystal-clear waters of the channel.

Upon arrival at Martillo Island, passengers have the opportunity to see penguins in their natural habitat. This is a unique experience, as few excursions in the world allow you to be so close to these animals without disturbing their environment and learning about them. Specialised guides accompany tourists during the tour, providing information on the characteristics of the species, their behaviour and the importance of the conservation of their habitats.

Penguin species

Two species predominate on Isla Martillo: the Magellanic penguin and the Gentoo penguin.

• Magellanic penguinThis is the most common species on the island, easily recognisable by its black and white plumage and a black band around its chest. Magellanic penguins are migratory, travelling thousands of kilometres between their feeding and breeding grounds. During the austral summer (October to March), they arrive on Isla Martillo to nest and raise their young.
• Gentoo penguinLess numerous but equally fascinating, the Gentoo penguin is the third largest penguin species. It is distinguished by its orange beak and a white spot over its eyes. These penguins also choose the island for breeding and can be seen interacting with Magellanic penguins along the coast.

In addition to penguins, Hammerhead Island is home to a large number of seabirds, such as cormorants and skuas, and on the other hand. During the rest of the year, the excursion also allows you to meet the friendly sea lions, which can also be observed from the boat.

The weather and the best time to visit

The best time to visit Martillo Island and observe the penguins is between October and April, when the colony is in full breeding activity.. During these months, temperatures in Ushuaia are milder, though still cool, with average highs of 10 to 15 degrees Celsius. However, it is important to remember that the weather in this region is very unpredictable, so it is recommended to bring warm and waterproof clothing, as well as footwear suitable for walking on wet or muddy terrain.

The importance of conservation

It is important to note that visits to Martillo Island are conducted under strict conservation rules to protect the fragile ecosystem and ensure the wellbeing of the species that live there. Excursions are regulated and only a few companies have permits to land on the island, which helps to minimise human impact on the environment.

Exploring the wildlife of Martillo Island and observing penguins in their natural habitat is one of the most memorable experiences you can have in Ushuaia. This excursion not only allows you to get close to the wildlife at the end of the world, but also provides an opportunity to reflect on the importance of preserving these unique ecosystems for future generations.
