Historical version 6 of Kew Gardens (view current version)
Royal Botanic Gardens
Possibly one of the most special parks in the world because Kew Gardens has possibly the widest variety of plants collected from all around the world, certainly the largest collection of botanical species in one place in the UK. As well as the outside park there are also several greenhouses including a high tech green house containing a large number of habitats.
If you are interested in gardens and plants, Kew is definitely worth visiting.
There is a fee to get in of several pounds (I think under 10) which is unusual for Parks in London.
Kew Gardens is run by the Royal Horticultural Society. Membership of the RHS gives you free admission to the gardens for yourself, and a number of guest tickets per year.
