Amazing Hotels: Life Beyond The Lobby

BBC2, 8pm

Giles Coren and Monica Galetti (above) return with a new series, donning their thermals at the ION Adventure Hotel in Iceland. This building extends out from a dormant volcano and visitors can expect the adventure of a lifetime. The duo go snorkelling in icy water between rock chasms and learn how to keep people safe on an erupting volcano. ★★★☆☆
