We cruise among the volcanic South Shetland Islands and the waterways of the Antarctic Peninsula, travelling ashore frequently in inflatable 'Zodiac' boats. Early in the morning of Day 5 (or, on the afternoon of Day 4 depending on weather conditions) you make your first landing. The itinerary focuses on the areas with the greatest promise of wildlife, and there are many options for frequent shore excursions. A few of the places we may visit are Livingston, Half Moon and King George Islands. Admiralty Bay, on King George Island, is a favoured feeding ground for Humpback whales and, with luck, you may see them dining on krill. Nearby, around 80,000 Adelie penguins have established one of the largest rookeries, alongside Gentoo and Chinstrap penguins. At crescent-shaped Half Moon Island, a breeding colony of Chinstrap penguins shares their territory with Fur seals and Blue-eyed shags; while at Livingston Island you may observe Weddell seals, Elephant seals, skuas, Giant petrels, terns and rookeries of Chinstrap, Gentoo and Macaroni penguins.
Weather permitting, you may also enter the flooded caldera of Deception Island, a recently active volcano and one of the most perfect crater islands in the world. Steam rises in places from the black sand beaches along its shores where the cold Antarctic waters mix with the steaming, thermal waters of the bay. This is dependent on suitable tides and hot water flows. You may also observe the island's large Chinstrap penguin colony before travelling to Paradise Harbour or Hope Bay, both situated on the mainland, to see some of the most dramatic scenery the continent has to offer. Icebergs of different shapes and sizes, which are calved from glaciers, erode into natural ice sculptures, while the sheer-sid ed, flat-topped 'tabular' bergs, which break from the thick ice shelves, are impressive. If the weather is kind, you'll have the opportunity to set foot on the Antarctic continent. One of the uncommon species in Antarctica is the human being, and we may see some at work in research stations maintained by several different countries. The days are long, and the short nights are often preceded by a wonderful twilight. Back on board, you will be tempted to spend time deck if conditions are still, just watching and marvelling at the glory of the passing scenery.
