If you are down the bottom of Chile, you could do worse than to take a run across to MPN. The Falklands are a stunning place to visit. Check out the mine fields and how the sand dunes around Stanley are in great shape where there are mines, but somewhat degraded in the cleared areas (because of human access).
There are the war cemetaries (Goose Green), offshore islands (eg Sea Lion Island) and flights on FIGAS.
In Stanley on the weekend, be very careful of meal times at the club - they close very early (like 6pm).
