Salisbury Plain and St Andrews Bay are the great king penguin colonies, each holding tens of thousands of breeding pairs on open ground behind the beach. Because king penguins take more than a year to raise a chick, the colonies are occupied year-round and you will see eggs, brown-woolly chicks and adults all at once — the sound and the smell are as much a part of it as the sight.

The tussac slopes and cliffs hold the great seabirds. Wandering albatross breed on Prion Island, light-mantled sooty albatross nest on the ledges, and giant petrels and skuas patrol the beaches. Access to some of these sites is restricted to protect breeding birds, so which ones your ship can land at varies.

The beaches themselves belong to the seals. Southern elephant seals haul out to breed from around October, with bulls fighting for beach territory; Antarctic fur seals follow in vast numbers through December and January, and the young males are genuinely aggressive — expect to be shepherded by guides carrying poles.

Grytviken, the old whaling station, adds the human layer: a museum, a church, Shackleton's grave, and reindeer-free hillsides recovering since the island's rat eradication, with South Georgia pipits and pintails now back.

November to March is the season. October and November bring seal breeding and snow-covered landscapes, December and January the peak of activity and the longest days, February and March the fattest penguin chicks and the best whale watching offshore.

Biosecurity

South Georgia enforces the strictest biosecurity of any wildlife destination: boots, clothing, bags and tripods are inspected and cleaned before you land, and boots are disinfected on the way ashore and back. Only your boots may touch the ground — you may not put bags down or sit. Highly pathogenic avian influenza has been present in the region since 2023, and while landing sites including the major king colonies have remained open, expect guides to scout each site before passengers land and to close one at short notice.
