Sri Lanka may be a small tropical island, but it holds one of the richest biodiversity landscapes in the world. Recognized as a global biodiversity hotspot, this island nation boasts a remarkable variety of wildlife, plants, and ecosystems — from misty cloud forests and dry plains to coastal wetlands and coral reefs.
For travelers seeking wildlife tours in Sri Lanka, this is a paradise where every corner of the island reveals a new discovery — whether it’s an elephant roaming the jungle, a brilliantly colored endemic bird, or a rare orchid deep in the rainforest.
