What to do & see in Iceland

When I think of Iceland I think of lovely colorful houses, amazing northern lights, hot springs and whale watching. This beautiful island is full of natural wonders and for sure a great holiday destination (and not just for layovers when you crossing the ocean). Having been living in Europe all my love, I am more and more thinking that I should explore more of the closer place rather than far away lands. Iceland has been on my watchlist for a spring trip for a long time.
