The south coast is the most scenery you can pack into one day out of Reykjavik. A single road runs east past a string of the island's most photographed places: Seljalandsfoss, the waterfall you can walk behind; Skogafoss, sixty metres of falling water you feel before you reach it; the black sand, basalt columns and heavy surf at Reynisfjara; and the small village of Vik beneath its sea cliffs. The longer trips push on to the glacier tongues, and the full days reach the ice itself. Below are the most popular south coast tours, with what each one actually reaches, how long it runs and what it costs.
