Start the day with a trip to the Skogafoss waterfall – one of the biggest waterfalls in Iceland, Skogafoss is 25 m wide and drops 60 m. To get close, maybe climb the long, windy set of stairs up to the scenic viewpoint. On a sunny day, you should be able to spot a rainbow or two in the spray. Continue along Iceland's South Shore to take in more of the country’s renowned natural wonders. From the stepping-stone rock formations of Reynisdrangar, the promontory of Dyrholaey, and the night black sand beach of Reynisfjara, this is one of the country's most scenic regions. This afternoon, visit the famous Jokulsarlon Glacier Lagoon – a sea of floating icebergs whose blue contrast with the charcoal sands of the beach. Stop for the night at a farm stay on the South Coast. Weather permitting, there will be another opportunity to step outside and witness the natural wonders of the Northern Lights tonight.
