The giant biomes of the Eden Project - the largest greenhouses in the world - have become one of Cornwall's most celebrated landmarks. Tropical, temperate and desert environments have been recreated inside the biomes, so a single visit can carry you from the steaming rainforests of South America to the dry deserts of Northern Africa.

There's an education centre, constructed according to the Fibonacci sequence, one of nature's most fundamental building blocks.

In summer the biomes become a spectacular backdrop to a series of gigs known as the Eden Sessions (artists have included José Gonzalez, Goldfrapp and The Magic Numbers) and from November to February Eden transforms itself into a winter wonderland for the Time of Gifts festival, complete with a full-size ice-rink. Those of you arriving by bicycle can enjoy discounted admission.
