Cresting the hill in Queen Elizabeth Park, this triodetic domed conservatory – an ideal indoor warm-up spot on a rainy day – is the area's green-fingered centerpiece. It has three climate-controlled zones with 400 plant species, dozens of koi carp and many free-flying tropical birds, including parrots and macaws: ask for a free brochure to help you identify the exotic flora and fauna. At the time of writing, the conservatory was under threat of closure due to funding issues so call first before you head over.
