The Sky Lagoon is Iceland’s newest thermal pool. The pool is pretty unique. Because of its position above the ocean, it almost appears to drop over the edge of a cliff into the sea.

Perlan collects the best of Iceland and places it in a large domed building on a hill overlooking the city. You can see exhibits on all sorts of things here. From the glaciers and how they’re retreating, to the wildlife in the oceans, the volcanic activity, and the elusive northern lights.
