Reynisfjara Beach

On the Ringroad towards Vik, this is a black sand beach on Iceland's southern coast. Three jutting rocks offshore are known as the Troll Rocks. There's also a cliff of hexagonal basalt columns that you can climb. A neat stop if you're in the area and have the time, but nothing you have to see.

Grjótagjá Cave

A beautiful cave near Myvatn containing a hot spring. You can't swim in the water, but the cobalt pool is picturesque, and a scene from Game of Thrones was filmed here if you're a fan.
