Orangutan Volunteer Program


Spend two weeks in beautiful Borneo at Samboja Lestari, a sanctuary that cares for approx. 125 orangutans and 72 sun bears. If you are passionate about protecting orangutans and want to make a practical difference, this program is for you. 


Situated within the Bornean tropical rainforest, Samboja Lestari remains one of the best and most accessible places in the world to see orangutans, whilst respecting the fact they are wild animals. Apart from orangutans, our centre is home to an array of other enchanting species like sun bears, binturongs and macaques.

As an Orangutan Program Volunteer, you will be a key part of our enrichment and welfare program. Enrichment programs are vital for captive orangutans, teaching them how to forage for food, build, modify and use tools, increase agility, and develop skills to survive in the wild. Take this opportunity to leave a long-lasting impact on Indonesia’s wildlife, working hard to provide a meaningful future not only for animals at the centre but also for the region’s wildlife for many years to come.

Our programs start on Sundays, and you can join us for two weeks or more between October and March each year:

Available start dates:  6th October, 20th October, 3rd November, 17th November, 1st December 2024;

How Can You Help

There are lots of ways you can support orangutans and help ensure the survival of this precious ape.

Adopt an Orangutan

Adopt an Orangutan

Orangutans are endangered and at risk of extinction. Habitat destruction results in hundreds of orphaned orangutans, who rely on our care every year. You can help by adopting one. Their dedicated ‘nannies’ teach them everything they need to know for when it’s time to release them back to the wild. You can follow their progress through Forest School.
