You can’t get much further away from it all than the literal ends of the Earth. True, the Arctic and Antarctic are cold, barren places. But they’re positively teeming with life, natural beauty and adventure opportunity. Whether you’re exploring the desolate white-and-aquamarine landscapes of Antarctica while communing with penguins or tracking seals and prowling polar bears in the Arctic, polar adventures are always well worth braving the cold. Travel tip: Pack extra mittens.
