The National Gallery is open after hours until 9pm on Fridays.

2. Get lost at the British Museum

One of the top attractions in London is the British Museum. It's bursting at the seams with fascinating artifacts from all over the world, from Egyptian mummies to samurai armor. Only 1% of the eight million objects in the museum are on display at any one time.

3. Tate Modern provides food for thought

Tate Modern is one of the most popular attractions in the city. You can enjoy the permanent collection for free. Winter is a good time to visit museums and galleries in London.

If you want to hop between Tate Modern and Tate Britain, you can take the RB2 boat from Bankside Pier to Millbank Pier.

4. Picnic at Greenwich Park

You can get a great view of the city from the top of the hill in the middle of the park. It is a great place for a picnic in the capital.

5. Snap a picture of the Houses of Parliament

The Houses of Parliament, also known as Big Ben, is a neo-Gothic wonder built in the 19th century. UK residents can get a free guided tour of the UK parliament, while the rest of us can pay for one online.

Visitors are encouraged to attend debates when Parliament is in session. The Prime Minister's Question Time is the busiest time of the day and only available to UK residents. Anyone can attend other debates without paying a fee.

6. Explore East London's incredible street art

It's hard to say where you'll find a specific display at any one time. Some areas of East London are known for their graffiti. Some decent artwork can be found on the side streets around brick lane.

7. Nab the free samples at Borough Market

It is fair to say that Borough Market is one of London's more well known spots. Located under a maze of Victorian railway arches and open on Mondays to Saturdays, the market is filled with lovely food and food lovers, featuring cuisine from all corners of the world. It's a great place for a grab-and-go breakfast or lunch, but also a great place for a stroll.

If you want to avoid the weekend crowds, go on a weekday. It's open all the time except Sunday.

8. Go to the Museum of London to understand the city better

One of the city's great attractions is the Museum of London, which provides a walk through London's various versions, from the geological history of the Thames Valley to the Anglo-Saxon inhabitants.

9. Kensington Gardens is full of delights

When you are done with the sights, you can take a stroll along the tree lined paths. Regent's Park is one of the Royal Parks that are free to enter.

If you're visiting between May and September, it's a good idea to bring a bathing suit.

10. Witness the Changing of the Guard

Every Monday, Wednesday, Friday and Sunday at 11am, there is a ceremony outside Buckingham Palace. The King's Guard will stomp around in time to music as they switch responsibilities with one another.

Windsor Castle has its own Changing of the Guard if you miss the Buckingham Palace ceremony.

11. Go face-to-face with National Portrait Gallery

The National Portrait Gallery has closed due to essential building works, but the British came to put a face to the names of famous historical figures from the country's past. The subjects of the paintings are more important than the artists. There are portraits of Shakespeare and Queen Elizabeth II.

12. Natural History Museum will surprise and delight

The Victorians were fond of collecting and cataloging. One of the most compelling results is that the Natural History Museum has an outrageously large collection of all things nature in a beautiful Gothic Revival building. There is a large blue whale skeleton in the main hall.

13. Appreciate the beauty within the Victoria & Albert Museum

The V&A has been open since 1852 and contains 4.5 million items. There are Asian swords, ancient Chinese ceramics, and plaster casts made from Michelangelo's David on the first floor of the museum. The oldest carpet in the world is from Iran in the 1500s.

15. Find out why St Paul's Church is called the Actor's Church

Not to be confused with St Paul's Cathedral, the church on the western flank of Covent Garden Piazza is also known as the actor's church. The first Punch and Judy show was held here in 1662.

16. Browse the stalls at Portobello Road Market

Portobello Road Market is located in the heart of one of London's best neighborhoods, and it sells everything from vintage clothes to antiques. There is always something going on on Saturdays and Sundays.

This enormous, ancient parkland is one of the best places to escape the city and catch a great view of it: the vista from Parliament Hill is so impressive it is actually protected by law. There is a zoo, three swimming ponds, and plenty of quiet places to picnic in the park.

In the winter, the pond is usually open from 7am to 2:30pm, while in the summer it is open until 8:45pm. In the winter, the pond closes.
