For a true experience of the White Continent we would always recommend a cruise. But for those without the time (or possibly the inclination) then there is a a day trip to the white continent with DAP airlines from Punta Arenas. The flight goes to King George Island, which takes around 2½ hours. To land safely, a clear sky with perfect visibility is required, and so three nights are needed in Punta Arenas. You will fly over the Magellan Strait, Tierra del Fuego Island, the Darwin Mountain Range, Cape Horn and the Drake Passage.
On arrival visitors are welcomed by an Antarctic-expert guide and are taken to visit Villa Las Estrellas (the first settlement inhabited by civilians), then take a zodiac boat to Ardley Island to visit some penguin colonies and navigate around Collins glacier and visit the Russian Orthodox Church at Bellingshausen Station before taking the return flight. Around 5 hours are spent in Antarctica.
Although we wouldn't recommend this trip, Last Frontiers have put together a package which includes four nights in the bohemian Lastarria neighbourhood of Santiago and three nights in Punta Arenas. Prices start at £6,353 per person based on two people travelling together and sharing a twin or double room. This includes breakfast throughout plus either lunch or dinner in Punta Arenas, transfers and all flights (overnight with Iberia, via Madrid).
