Venture into the jungle at Gunung Leuser National Park. The trees grow so close to each other that you can hardly see the path.
You can trust your guide. He will take you safely to where you will meet the orangutans. You will be moved to see these large red-haired creatures swinging on the trees, feeding, carrying their babies. Or just looking at you with wise and innocent eyes.
Hike on. Keep your eyes open, because there are many animals here besides the orangutans. Take a bath in the waterfall, spot orchids, and close your adventure by tube-rafting down Bohorok River.
