The waterfall of Skógafoss (Iceland) topples over a rocky cliff at the western edge of Skógar in dramatic style. Climb the steep staircase alongside for giddying views downwards, or walk to the foot of the falls, shrouded in sheets of mist and rainbows.
This geothermal spa is one of the biggest attractions in Iceland for good reason: The water is warm enough to swim in even when it's freezing outside, and it's also rich in minerals like silica and algae that give it its bright blue color.
I always arrive in Jökulsárlón at night so I can make the most of the first light of day when there's nobody else around. At midnight in June, the colors of the sky, the water, and the earth have the good taste to be perfectly complementary (pink/cyan). The birds seem to appreciate it as much as I do.
