If you want to go to one website on Antarctica (and, I gotta’ say, I’m not really sure why most people would want to go to more than that) Discovering Antarctica from the Royal Geographical Society is the place to go.

It’s got pictures, videos, and a whole lot of interactive features that are accessible to English Language Learners.

Since the geography book I use in class doesn’t say a word about Antarctica, and I have my Geography webpage set-up to mirror the book, I’ve placed it in the Sites That Cover Many Areas category.  It’s about fifteen links or so from the bottom.
