Orangutan + sun bear sanctuaries
Samboja Lestari Orangutan Sanctuary is one of Indonesia’s most prestigious and renowned orangutan rehabilitation and rescue centres. The emphasis is on the rehabilitation and release of orangutans, many of whom were rescued from atrocious situations. Our Sanctuary also includes a 58 hectare area for over 70 resident sun bears which have all been rescued from the illegal pet trade or areas of major deforestation.


“I loved walking through the forest, the variety of plants, flowers, trees and animals. There was so much to discover. It was so peaceful and quiet – and still you could always hear different animal noises.”
“The yoga was wonderful and to be starting my day with those views across the rainforest, the sound of the rain coming down and Rebeca’s calming but challenging yoga was the perfect start to each adventure.”
“TThanks to the organizers of the program! What you and BOS achieve in general is unimaginable and to see it upclose is wonderful. I would also like to commend the staff at Samboja Lodge. Everyone is very friendly, motivated and seems very happy.”
