The onyx black sand of Reynisfjara is formed from volcanic activity in Iceland: when lava collides with the ocean, it rapidly cools and shatters into small fragments of basalt. With its enormous basalt stacks (features in Game of Thrones and once believed to be petrified trolls), roaring Atlantic waves and stunning vistas, Reynisfjara is widely considered to be the most beautiful example of Iceland’s black sand beaches. The sea stacks along the shore are home to thousands of nesting seabirds like puffins, fulmars and guillemots — a must-see for birdwatchers. A visit to Reynisfjara is included in most tours of southern Iceland. Driving here is a good option, too, since it's only about 180 km from Reykjavík.

In the year 64 AD, Emperor Nero built a palace almost one mile long — stretching from Palatine Hill all the way to Oppio Hill. Some parts were covered in gold, precious stones and featured splendid decor. After Nero’s death, it was filled in with earth to obliterate the tyrant’s memory. It was accidentally rediscovered in the 15th century, and today, you can walk through 30 of Nero’s 150 underground rooms.
