Family Day Out For £40

Morning: Explore London's Parks

Start your day with some fresh air in Kensington Gardens and Hyde Park.

Visit the popular Diana, Princess of Wales' Memorial Playground, where kids can climb the giant wooden pirate ship and explore the sensory trail, beach and teepees.

Take your rollerblades and join skaters of all ages on the nearby Broadwalk.

Wander across Kensington Gardens to Hyde Park and the magnificent Serpentine lake.

The Serpentine is home to a large number of birds, many of which are winter visitors to the park. You're likely to see ducks, geese and more exotic looking species like Great Crested Grebes.

Lunch in London for Less

Take a packed lunch and eat it in the park, or head to the Science Museum's indoor picnic area.

Afternoon: Enjoy London's Free Museums

Walk down Exhibition Road to South Kensington's brilliant child-friendly museums.

The Science Museum and Natural History Museum both offer free entry (apart from some temporary exhibitions).

Science Museum

The Science Museum is packed full of fun family activities.

The Garden, aimed at three to six year olds, is a multi-sensory area where children can explore floating and sinking, shadows and reflections, sound and giant building blocks.

The Launchpad gallery is great for older kids, with more than 50 interactive exhibits, plus electrifying shows and demos, all based on the wonderful world of physics.

Natural History Museum

Next door at the Natural History Museum, get up close to a terrifying T-Rex and find out how baby dinosaurs were born.

Visit Investigate, the hands-on science centre for seven to 14 year olds, and get your hands on geological specimens in the Earth Lab.

Under-sevens will love the free Explorer Backpacks, which contain an explorer hat, binoculars and drawing materials.

Catch the Tube to Covent Garden to watch the colourful street performers.

Mime artists, acrobats and bicycle stunt performers are among the regular acts that appear in the Covent Garden piazza.
