The Eden Project is a great place to visit. The main feature is the pair of biomes – one for a Mediterranean environment, one for rain forest. Even on a cold rainy day in Cornwall, you can wander around a warm, humid rain forest, and then pop through to the mediterranean for lunch in an ‘outdoor’ restaurant.
There are also numerous art installations around the site, which change fairly often.
