These are not just clusters of trees, but living archives, ecosystems that have survived ice ages, tectonic shifts and the rise and fall of empires. Across continents, a handful of ancient forests still stand, offering travellers a rare chance to walk through deep time.1. Daintree RainforestEstimated to be around 180 million years old, this is the oldest tropical rainforest on Earth. Its biodiversity is staggering, with primitive plant species that trace back to the age of dinosaurs.2. Borneo Lowland RainforestDating back roughly 130 million years, this forest spans Malaysia, Indonesia and Brunei. It’s one of the richest ecosystems globally, home to orangutans and pygmy elephants.3. Taman NegaraOften cited among the world’s oldest rainforests, it is over 130 million years old. Visitors can explore canopy walks and dense jungle trails in this pristine ecosystem. A farm on an island in the ganges delta, Sunderban are)a (Photo: Freepik4.
