World's Most Secret Hotels

We uncover more unique and unusual hotels in Jordan, England, Sweden and Ecuador, including the Bubble Wadi Rum Luxotel resort that resembles a colony on Mars and a converted plane.

More hidden hotels are revealed in Uruguay, Sweden, Scotland, Oman and The Netherlands - from a camouflaged resort perched on the edge of a mountain, to mainland Britains most isolated hotel.

We uncover some truly remarkable and hidden retreats in Canada, Iceland, Sweden and the UK - from underwater sunken hotels to remote retreats surrounded by lava fields.
