By boat through Beagle Channel
Antarctica Voyage on Ocean Nova and Patagonia journey
I believe our chose was the best! There were only twenty passengers in our ship, and our guide was excellent! She was speaking English well, and told us many interesting things about Beagle Channel, its history, navigation, aborigines and wildlife.
Our boat was small enough to approach very close to the rocks. We could watch seals and cormorants closer than it is usually possible in zoo. Life on the rocks is very active. Everything is moving, flying, jumping screaming, and certainly smelling. We could see all the details of it with the open upper deck of our boat as a good viewpoint, like the balcony in a theater.
We passed also very close to the lighthouse Faro del Fin del Mundo. You can see it in any set of Ushuaia's pictures. Somebody says that it is the world's southernmost lighthouse, but that isn't right because of the Cape Horn lighthouse. May be Faro del Fin del Mundo was built before any more southern lighthouses and was the southernmost one in the past? I don't know.
Our amazing excursion was finished by a walk at one rather large island, where we saw some interesting plants and even a possible site of an ancient Aboriginal village. After that we returned in Ushuaia.
