From South Georgia Website
All travel has inherent risks, but travel to South Georgia carries a greater level of risk then to many, more traditional, destinations.
There are no medical facilities for visitors. In an emergency, there is a possibility of accessing the support offered to visiting fishing vessels at King Edward Point. But this is not available elsewhere on the Island.
There is no search and rescue, or other emergency service on the Island.
There is no independent transport from South Georgia to the Falkland Islands or to South America, which are at least three or five days sail away respectively.
Visitors should be aware of the above when considering going to South Georgia. Although the Government requires all visitors (other than authorised Government researchers) to ensure they have vessel-based support throughout their time in South Georgia before issuing visit permits, the grant of a permit does not imply that the Government accepts responsibility for providing any additional support.
South Georgia by Sea
South Georgia is only accessible by sea.
Most people visit by cruise ship. You should check before booking what your ship's South Georgia itinerary will be as this will vary. Vessels which as members of IAATO have greater access to landing sites.
