A buddy of mine visited Iceland two years ago.
He loved the variety of outdoor attractions there.

He recommends the Skogafoss waterfalls, Black Sand beach, and of course a tour of the Northern Lights.
As for tourist landmarks, check out the Reyjavik Concert Hall and Conference Centre.
-quite a bit eye candy in Iceland too with the blondes there too.
