Grytviken is the whaling station made famous by Shackleton's reunion with civilization on South Georgia after losing his ship, the Endurance, to Antarctic pack ice in 1915. Toast "Bring 'em Back Shack" at his gravesite in a small cemetery overlooking the bay. Although the grave of Earnest Shakleton can be found in the little graveyard here, Grytviken is not the whaling station where he finally found help after his epic journey. This was at the nearby Stromness whaling station.
The usual way to arrive is by ship.
The abandoned whaling station has undergone a project to remove all asbestos and dangerous collapsing buildings and may be explored. The station was active in the whaling industry until the middle of the last century. In the meantime the museum, operated by Tim & Pauline Carr, is an excellent place to learn about the natural and whaling history of the island. Other popular visitor destinations include the restored Norwegian church, and the cemetery, which contains the grave of the famous explorer Ernest Shackleton.
There is a small gift shop in the museum that sells books of local interest, posters, and sundry other souvenirs. British pounds, Falklands pounds, Euros, and American dollars will all be accepted, as will Visa and Mastercard (but not AMEX). The Post Office is open upon request 1km away at King Edward Point and may be brought on board larger ships. The Post Office has a range of postcards, stamps, first day covers, South Georgia coins and a few South Georgia Government publications for sale.
You will need to bring your own food, unless you can catch penguins.
