National Botanical Garden of Wales - Llanarthne, Camarthen, South Wales
I think that the large greenhouse in this garden is as good as or even better than the more famous Eden Project in Cornwall. The garden is built in a valley in South Wales and is beautifully designed and set out. The temperate greenhouse shown above has one of the largest single span glass roofs in the world and has a large collection of South African, Californian, Mediterranean and other temperate plants. The are also lots of good educational exibits in the greenhouse and around the garden making this garden a very good day out for both adults and children.
