Stunning photos from inside the glistening underground spaces show a warm orange glow spreading out across the horizon of Iceland's Vatnajokull glacier. The bright sunlight streaming in bounces off the deep blue of the caves walls, warming its icy inside.

This beautiful sunrise is enough to warm the chilliest of places – including ice caves!
The pictures were taken on January 2 at Icelands Vatnajokull glacier, fully reflecting the countrys reputation as the Land of Ice and Fire.

Photographer Sigurdur William Brynjarsson even managed to silhouette himself in the caves entrance for one of the most striking shots. These ice caves are created by water that trickles down through the glacier and then drains out at its base and although the caves are flooded in the summer, in winter it freezes and the caves drain out.

Sigurður, owner of Artic Shots, said: "My favourite shot is the selfie I took where I'm standing in the entrance to an ice cave called the Crystal Cave.
"The day in general was phenomenal. We woke up early that morning and headed out to drive to the Glacier Lagoon.
"In a truck with man-sized tires we made our way towards the glacier and its magical ice caves.

He added "The ice at the base is called blue ice and due to the weight of the glacier having squeezed all oxygen out of the ice, it turns incredibly blue.
"We came to the glacier ahead of the crowds and got to enjoy and photograph the fiery sunrise in peace.
