WINDOW
OF THE WORLD
Most people travel to see the beautiful sights that the
world has to offer. 1 Thankfully now, you don't
have to choose. In Shenzhen in China, you can see all
of the world's most amazing sights - at the same time!
Window of the World is a theme park with a difference.
2 There's the Taj Mahal, the Eiffel Tower and
even the pyramids of Egypt! It's like travelling around
the world in a single day!
As well as the miniature models, the park also offers
fun activities for the whole family. There is an amazing
climbing area as well as a large indoor snow dome.
3 Then, to end their day, they can enjoy a
beautiful fireworks display in the evening.
A visit to Window of the World costs £17 for adults,
with half-price tickets for children. 4
quite a bargain for a round-the-world trip!
