WHAT TO DO IN LONDON...
1 WHEN IT'S VERY COLD Go ice skating at Somerset House, Somerset House is a beautiful 18th century building on the river Thames. In the winter, the area in front of the house is made into an ice-skating rink. There is a skating school, where you can have lessons, and there are also late-night sessions and DJ nights. In November and December there is an enormous Christmas tree, and the café serves special Christmas food 2 WHEN IT'S RAINING Go to South Kensington, and visit three wonderful museums. You can walk from one to the other because they are all very near. The Science Museum is very popular with adults and children, and also the Natural History Museum, which has life-size robotic dinosaurs and other fascinating exhibits. The third museum, the Victoria and Albert Museum, is full of art and design from all over the world. It has an amazing collection of fashion from the 17th century to the present day. And if the sun comes out, cross the road into Kensington Gardens, one of London's many parks, and visit the famous statue of Peter Pan.
3 WHEN THE SUN IS SHINING Go to Hampstead Heath, London's biggest park. From the top of Parliament Hill, in the south part of the Heath, you can see many of London's famous monuments, including St Paul's Cathedral and the London Eye. Have a picnic, and then, if it's hot, walk to the open-air swimming pool, where you can swim with plants and trees all round you. It is a magical place, and you can't believe that you are in the middle of a capital city.
