Sinharaja Rainforest: Sri Lanka’s Lush Biodiversity Hotspot

Sinharaja—literally meaning "Lion Kingdom"—is Sri Lanka's last major undisturbed stretch of primary tropical rainforest. It spans over 11,000 hectares of dense, green wilderness and is home to over 50% of the country’s endemic species of mammals, butterflies, reptiles, and plants.

This forest is a treasure trove of biodiversity:

• Over 140 bird species, including the Sri Lanka blue magpie, red-faced malkoha, and green-billed coucal.

• Rare mammals like the purple-faced langur, leopard, and giant squirrel.

• An astonishing variety of flora, much of which is found nowhere else on Earth.

 Travelers here access the rainforest via Deniyaya (east entrance) or Kudawa (north entrance). Trails vary from short, easy walks to more strenuous hikes for serious explorers.

You’ll be accompanied by mandatory local guides—not just for safety, but to unlock the secrets of the forest. These guides know every call, footprint, and leaf.

Things you might experience:

• Birdwatching tours starting early in the morning

• Natural pools and waterfalls tucked into the forest interior

• Medicinal plants and centuries-old trees

• Sudden encounters with monkeys, reptiles, and butterflies
