Visit a research station in Antarctica

Fly or ice-break to the Snow Hill or Gould Bay colonies to stand among thousands of the largest penguins on Earth.

Sail past icebergs, glaciers and penguin colonies.

Stand at the bottom of the world.

Paddle silent bays beside sculpted icebergs while penguins porpoise alongside and seals watch from the floes.

Hotel rebuilt from Torne river ice every winter, art suites and all.

Sail through a narrow gap into the flooded caldera of an active volcano, past a ruined whaling station and beaches warm enough to dig a hot bath.

Experience complete silence in an anechoic chamber, a room designed to absorb all sound reflections. Visit Orfield Laboratories in Minneapolis (holds a Guinness World Record for the quietest place on Earth at -24.9 dB(A)) or the anechoic chamber at Microsoft's Building 87 (known for testing audio equipment). The extreme silence can be disorienting, and visitors often hear their own heartbeat and internal bodily sounds.

The world's oldest and largest spaceport.
