There's so much to see, with butterflies of every colour perching on every branch. If you're lucky, you might even have one land on your shoulder.
If you've brought a camera, you might have problems with the lens steaming up to begin with. However, after about 15 minutes the camera should get used to the tropical temperature, and you'll be free to get some great photos.
It's not just about butterflies. They also have one of the largest insect collections in the UK and a selection of reptiles. Two free-ranging iguanas also live here, so keep an eye on the treetops and you may spot one.
