With multicoloured lights gently glowing from a translucent ceiling, a stream rippling through rocks beneath and a bright light in the distance, this tunnel looks like a passage to fairytale world.
But this breathtaking photograph was taken in cave carved out of the living rock and ice of this world - albeit on a remote fringe little visited by outsiders.
These incredible pictures show ice caves carved by volcano-fed hot springs through the glaciers of Kamchatka.
They were captured by local guide and photographer DenisBudkov, Natalia Balentsova, a photographer from Chelyabinsk, and others on the peninsula on the eastern edge of Russia's vast Siberian land mass.
The intrepid snappers came across the magical caves by chance while on expedition near the Mutnovsky volcano, some
45 miles south of the regional
capital of Petropavlovsk-Kamchatsky.
