The peninsula jutting out from Antarctica, just below South America, is the most accessible part of the iced continent.
I worked the Antarctic peninsula on Silver Cloud in 2018.
This Antarctic Peninsula is by far the most heavily visited part of Antarctica. As the piece that pokes the furthest north, it is also the area with most wildife, and also the place with the most human history and settlement.
There are quite a number of different sites that ship can visit, although most of these sites serve a similar biological or cultural function.
Despite the common misconception, there is not a high diversity of wildlife here. On a typical trip, yyou should the three main penguin species. In fact, there is a bigger range of animals to be seen travelling along the Beagle Channel coming back into port!
However, there is some good concentrations of seabirds, and many colonies. Because of the large amount of visitors, there is an attempt to have the ships and sites rotate.
There are a LOT of ships that go the Antarctic peninsula. This is the main money maker for many expedittion ships. In fact, there are even some companies that ONLY go to here and the Arctic.
There is a large range of sites to visit around the peninsula.
