In reply to MikeR:
December is southern summer; maritime climate and low elevations, don't think you will get much use from the skis
Not sure about climbing, but I remember lots of rocky ridges, bound to some bouldering
Many of them were battle sites though...fairly sobering to think what went on there.
Make sure you take in some wildlife watching, the only place to see king penguins in the wild outside the polar regions...!
Cheers
