Ice climb in London
The huge ice skating area at Somerset House has been drawing crowds each winter for years, but last November an ice wall was added for the first time, bringing even more danger and excitement. Standing more than 26 feet high is a long line of pure ice, featuring three climbing faces of varying difficulty using crampons (防滑鞋), ice picks and ropes. Using it costs about ￡40 (020 78454600; www.somersethouseicednk.org.uk). It is open from late November to the end of January.
