Not far from Richmond and still in the same area is Kew Gardens. You can easily spend a few hours walking around the gardens and many buildings that make up Kew Gardens- London’s largest UNESCO Site.
The Glasshouse is one of the main features of the gardens, it’s a grade 1 listed building home to rare and threatened plants. The Hive is also a must see and one of my favourites which highlights the extraordinary life of bees.
In addition to this there is a treetop walkway which is really unique and fun for children and adults. You can walk 18 meters above the woodland below and take in views of the gardens and the nearby areas.
