Located within the grounds of the Pavel Šafarik University, Košice’s Botanical Garden is an oasis of verdant fauna that is home to thousands of plants, animals, flowers and the rest. Of particular interest is the vast collection of cactuses (or cacti? We never knew), with over a thousand of the spiky pests lurking in this expansive garden. There is also the opportunity to spend some time in a greenhouse and see if you could deal with the intensely muggy conditions of a rainforest, so consider that an ideal practice before you go off to live in the Amazon.
