In the far south, there are several abandoned British research stations. We visited one at Horseshoe Island and saw another from the ship at Stonington Island.
These stations are nicely kept and form a sort of time capsule of how life was on Antarctica in the 1950’s. You are allowed to visit them, as long as you don’t touch anything and clean up after you leave. For many of us one of the highlights of our trip to the deep south.
