After the Golden Circle tour, drive about two hours south to see Black Sand Beach and Skogafoss waterfall(about 20 mins from each other). Both are completely magical places. These basalt beams I’m standing on were formed after a volcano erupted and cooled to form cracked columns through a process known as columnar jointing. Reynisfjara, or Black Sand Beach, is a truly special place! Parking is free but get there early to avoid crowds or bad weather.
