In August, Africa plays backdrop to one of the great wildlife spectacles: the annual migration of over two million wildebeest from the Serengeti plains to the grasslands of the Masai Mara. In Colombia, the start of August heralds the annual flower festival in Medellin. It attracts visitors worldwide with more flowers than you’d imagine possible, fireworks and live music. Or travel to Kandy in Sri Lanka at the time of the Parahera Festival held at the Temple of the Tooth, where Buddha's tooth is said to rest. Get swept up in dancing and parades by torchlight.
