4. Get trapped in the Princess of Wales Conservatory

These high-tech modern glasshouses display 10 different climatic zones,from dry desert to wet tropics. Orchids are flamboyantly showcased in one section. The giant water lilies the size of cartwheels are marvellous,and the “corpse flower” or giant titan arum,is as stinky as its reputation. But don’t miss the small and seemingly modest carnivorous plants,which include Venus flytraps,pitcher plants,and other ingenious flora adept at swallowing up unwary insects.

5. Spot the dragons at the Great Pagoda

Chinoiserie was all the rage in 1762 when this pagoda was built by a Scottish-Swedish architect. There isn’t much that is truly Chinese about it apart from its suggestive shape,but who doesn’t like a good folly? The pagoda rears 10 storeys high and is decorated with 80 wooden dragons painted green with gold wings. You can clamber up the pagoda (book a time slot) for a view all the way to central London.

6. Ascend the Treetop Walkway for a bird’s eye view

Pant up 118 steps to this metal walkway in the arboretum for a good outlook over the gardens as you zigzag between a canopy of chestnut,beech and oak trees,which are an especial delight in autumn. You’ll hear the dainty cheeping of British birds,and might spot squirrels. The walkway is 18 metres above ground,and those with no head for heights might be unnerved at its mesh floor and shivering movement on a windy day.

7. Learn about Georgian-era food in Kew Palace

One of London’s least known royal palaces was built in 1631 and became the summer family retreat of King George III. Entry is included in the gardens ticket,which makes this a good retreat if it rains. The interior’s relative simplicity and Georgian elegance is a pleasing contrast to the baroque bling of other palaces,but the most interesting part is the kitchens,where you can learn about life below stairs.
