Why Martillo specifically

Most penguin colonies in Patagonia are observed from a boat or from a fenced viewing platform. On Martillo Island — different: tourists walk on a path right through the colony. The penguins aren't afraid of people and come up close.

This works because the island is closed to outside boats. Only licensed boats from Estancia Harberton have the right to land tourists.

Three penguin species

Magellanic penguins — the most numerous. Recognized by the black-and-white stripe across the chest. They live in burrows they dig themselves.

Gentoo penguins — slightly larger, with an orange beak and a white patch on the head. The fastest swimmers among penguins.

King penguins — a rarity. Tall, vivid, with orange patches on the neck. They appear infrequently, but meeting them is one of the most striking experiences.

When to go

Penguins are on the island from mid-October to early April (Patagonian summer). Peak numbers and activity — November–January: this is when they hatch eggs and chicks appear. In February–March the colony begins to thin.

We don't recommend planning for May–September: the island is practically empty.

Route and logistics

The day starts in Ushuaia around 9:00. Drive east along Ruta 3 along the Beagle Channel — about 1.5 hours. Along the way we stop at Andrés's farm (berries, mushrooms, local food) and at the fishing village.

From Estancia Harberton to the island — 20 minutes by boat. On the island 30–40 minutes walking among penguins. Return to Ushuaia by 19:00.

How much the boat costs

  • Without landing — $140/person: the boat goes around the island, penguins are visible from on board
  • With landing — $250/person: you walk through the colony

We recommend the landing option — that's exactly what people come to Martillo for.

Guide for the full day — $580 per group of up to 3 people. The boat is paid separately.

What to bring

A warm jacket — by the water it's cool. Waterproof shoes — there are puddles and wet patches on the island. A camera with zoom — although the penguins come close themselves, the zoom comes in handy for chicks in the burrows.
