Visitors worry that London is an expensive city but there really are so many things to do for

free in London from museums and galleries to free music and walking tours.

Art Galleries

Tate Modern and Tate Britain are exceptional national art galleries housing some of the finest artworks in the world. Tate Modern focuses on contemporary art while Tate Britain displays British Art from the sixteenth century to the present day.

Museums

All of London's major museums are free, but most offer some special exhibitions for a fee. My favorite is the Museum of London where you can learn the history of London from Roman times to today. Other great major museums are the British Museum, the V&A, the Science Museum, and the      Natural History Museum. Oh, and I love the Geffrye Museum. And the. Now I can't decide which is the best!

Many of London's major art galleries and museums are open in the evening and often have special evening events. This can be a great way to relax at the end of a busy day seeing the sights. The main London galleries and museums are air-conditioned so it can be a wonderful way to cool down in the height of summer in the city. Galleries and museums are not open late every night so here is a handy list to help you plan your days and evenings.

Royal Parks

Many people say the Queen Mary's Rose Gardens in Regent's Park is their favorite spot in London, and who am I to argue? I would also recommend St. James's Park as it offers one of the best views of Buckingham Palace. Hyde Park is enormous and includes the ever popular Diana Memorial Fountain and the Peter Pan Statue.

There are often free talks and guided walks in the royal parks so do check the What's On section of the Royal Parks website.

Changing of the Guard

No visit to London is complete without seeing this military tradition. The Queen's Guard in London changes in the Forecourt inside the gates of Buckingham Palace at 11:30am every day in the summer and every other day in the winter. Get there early and view the spectacle from outside the front gates.
