We camped for two nights in þingvellir national park, just beside the lake.  This turned out to be one of our favorite campsites throughout the trip.  Waking up early in the mornings we'd catch a glimpse at those who got up early to fish, all the while sipping hot tea, eating warm cereal with cranberries, cinnamon and peanut butter. Trying to savor the last few pages of "Sputnik Sweetheart" by Haruki Murakami. 

This place became home instantly.
