The jungles of Sumatra are defined by many ‘superlatives’. The three national parks of Bukit Barisan – Gunung Leuser, Kerinci Seblat and Bukit Barisan Selatan – are home to the last surviving Sumatran Tiger, Leopard, Rhino and Elephant, the largest flower on Earth, the highest volcano in Indonesia, the highest lake in Southeast Asia, and some of the most significant ethnic minorities on Earth – the Minangkabau tribes.
