Mate, been a few years since I was last there and they were still doing work to enlarge it. Basically 2/3 huge glass domes with flora and fauna from around the globe that we are trying to keep from extinction. i really cannot remember a huge amount. But if you are in and around that area visit Bodmin moor, Port Issac, Mevagissey, Pentewan harbour, the wee pub next to it is superb. That whole area of the country has something different around every corner. Enjoy.
