The orchidarium is housed in a glass-domed contemporary building and surrounded by lush landscaping. There are 1500 species of orchids here, the largest collection in Europe, as well as 5000 subtropical plants, flowers and trees. A meandering path takes you through the exhibition space and past a dramatic 17m-high waterfall; the sound of water acts as a soothing backdrop to your visit. Note that an entry charge may be introduced in due course.
