I’m wondering about ways to visit, I believe it's cruise only, and the potential costs and best times of year. I have seen some amazing pictures of South Georgia island which can be included in the longer cruise itineraries. I priced out National Geographic, which has been recommended to me by someone who is a photographer but the starting price was $27,000 for 1 person w/o airfare.
I looked at cruisecritic and had to laugh at the itinerary maps. The maps must be automatically drawn because they are adding ports (I assume with similar names) in Scotland, Australia, and West Africa between leaving Argentina and arriving in Antarctica. I was also surprised at the number of cruises advertised as being "Antarctica cruises" on cruisecritic that just round the tip of Argentina and go nowhere near Antarctica, making it look like a dishonest website.
