There are lots of ice skating rinks around London this year. A few years back it seemed there were just a few, but there are now now fewer than 11 in or around London!

The rinks this year are the Broadgate Ice Rink, which actually is around for 6 months or more, the Natural History Museum rink, Canary Wharf, Somerset House, Tower of London, Kew Gardens, Royal Windsor Hampton Court Palace, Greenwich, Hampstead Heath, and Forty Hall.
They are listed in full here at visitlondon.com. Costs range between about £5 to £12.50. Just be careful not to break anything!
