In April of 2010 Don and I did the 5 day/4 night Fjords of Tierra del Fuego cruise with Cruceros Australis. The one way cruise starts in Punta Arenas, Chile and passes through a beautiful region of glaciers with a visit to Cape Horn before arriving in Ushuaia, Argentina. The trip includes various shore visits to explore the local flora and fauna with great sighting of elephant seals. October through March you can also see penguins at Magellan Island.
The photos below, taken in 2010, will give you a taste of what this area has to offer. I refrain from adding more of a review of services, food and accommodations as it was so many years ago. I will say that at the time we were quite pleased with the quality of the trip.
