Thrill-seekers can get the chance to sleep in a snow hole in the middle of the Scottish mountains overnight in a unique holiday experience.
Adventure holiday company Scot Mountain Holidays allows people to construct a communal bunker deep in the Cairngorms national park before spending the night lit only by candle light.
Billed as "not for the faint hearted", a video clip shows campers in sleeping bags in the snow hole that they helped build.
