This is Reynisfjall, a cliff face with famous basalt caves named Hálsanefshellir.
The beach is Reynisfjara, one of the loveliest but most dangerous black beaches of #Iceland.
To get this shot, I had to get as far away as I could, turning my back to the sea. I was with my partner and he was watching the waves. I took the photo as quickly as I could, and we moved back to a safe distance from the sea.
