What to do in Ushuaia in January

Explore the Beagle Channel

Take a boat tour to enjoy mountain views, rocky islands and, on applicable itineraries, the famous Les Eclaireurs Lighthouse. Pick the length and route that match your interests.

Watch penguins around Martillo Island

January usually falls within the penguin observation season. Confirm whether the excursion is a boat-only viewing experience or includes a different type of access. Availability and conditions vary among operators.
