Help to rehabilitate the largest number of rescued orangutans in the world by volunteering at this orangutan sanctuary – made famous by the TV show Orangutan Jungle School!
Below is an example of a typical two-week itinerary. Please note that some activities may be subject to change during your stay, as they are dependent on weather conditions and the requirements of the project at the time.
You will stay in either an authentic longhouse or one of two houses situated opposite in the jungle surroundings of the sanctuary's grounds. Rooms are based on a twin-share, same-sex basis with 1 double room available for couples at request. Each room comes complete with bed linen, a fan, and mosquito nets. All rooms have their own en-suite bathrooms, complete with a western toilet, shower, sink and mirror. There is a kitchen and communal area in the longhouse, which is free for all volunteers to use, and has free Wi-Fi available, but please bear in mind that the signal can be intermittent. There is a free, regular cleaning service if you wish for your room to be cleaned and there are also laundry services available, though this come at a small fee.
Volunteers enjoy three meals per day at the project, with all meals and drinking water included in the project fee. Your lunches and dinners will be prepared for you and will consist of typical Indonesian food, such as rice, noodles, and fried vegetables. Breakfast, however, is prepared by volunteers, but the food, such as cereal, yoghurt, bread and eggs is supplied. Vegetarians can be catered for but please let us know in advance so the appropriate food can be purchased. (If you have any severe nut allergies, please contact us prior to booking.)
Alcohol is permitted and beer can be purchased at the sanctuary but may only be consumed at the volunteer accommodation. Snacks are not currently available onsite, but they can be purchased from a small local store which is a 15 minutes walk from the accommodation.
This project is based at a rehabilitation sanctuary, and there are orangutans here year-round, meaning there is no real preferred time to volunteer regarding the animals.
The weather is also quite constant throughout, and whilst it can rain at any time of the year due to the rainforest climate, you can expect mostly dry weather with temperatures averaging 32°C (90°F) in the daytime and 23°C (73°F) at night.

You will need to fly into Palangkaraya Airport on your project start date, arriving between 8am-5pm, with most international flight routes going via Jakarta International Airport (Soekarno-Hatta International Airport). Upon arrival into Palangkaraya Airport, you will be met by a project representative in the arrivals hall who will then transfer you to the Nyaru Menteng Orangutan Sanctuary. This transfer takes approximately 40 minutes.
If you arrive a day early and stay in a hotel close to Palangkaraya Airport, we will be able to arrange your transfer to Nyaru Menteng from there.
To join this project, you will need a Social Visa (C6), which you must obtain prior to arrival in Indonesia. This visa permits a stay of up to 60 days and can be applied for with ‘My Visa Indonesia’. We will provide all the necessary documentation you require and the cost of this visa is approximately $250.
Please note, your passport must be valid for a minimum of 6 months from your date of entry into Indonesia.
There is a moderate level of fitness required to take part in this project. There may be small construction tasks that will take place in humid conditions, as well as short walks which involve walking uphill. The other tasks are not too physically strenuous, but for the reasons mentioned above, we advise that you ensure you can cope with the few physically demanding tasks involved. There are no specific skill sets or experience that are required to join this project, but volunteers must always be willing to work as part of a team.
To volunteer on this project, you must provide negative test results to show you do not have HIV or Hepatitis B or C prior to arrival. A chest x-ray or QuantiFERON blood test to show you do not have Tuberculosis is also required. These are ESSENTIAL, as without them, you will be unable to join the project.
Due to Covid-19, additional safety measures have also been introduced to ensure the safety of all volunteers, staff members and the orangutans. These can be viewed by clicking here and may change at any time.
We are often asked whether or not volunteers will have the chance to touch or play with the orangutans whilst on this project. Our answer to this question is, and always will be no, and this is for good reason.
Orangutans are highly susceptible to human diseases, many of which are far more dangerous to an orangutan than they are to us. Also, an environment of constant change, with new volunteers going to the project every two or four weeks and being in contact with the orangutans would be very detrimental to the orangutans' well-being. With no consistency in their lives, behavioural problems arise. They also have a tendency to begin to trust humans which is damaging should they be released back into the wild, as they will become easy targets for poachers. Finally, an orangutan is around 7 times stronger than an adult male human so a no-contact policy is just as crucial for your safety as theirs.
That is not to say that you will have no interaction with the orangutans, it simply means that you will have no direct contact with them. You will still observe them on a daily basis and see how your contribution to their husbandry and enrichment makes a real difference to the lives of these apes. For more information, please view our article on hands-on contact with orangutans.

Otan once stole the spotlight on Channel 4’s Orangutan Jungle School during a lesson on snakes. Now 12 years old, he has finally found his true home in the wild of Bukit Baka Bukit Raya National Park. Released just last month, he stands as a shining example of BOSF’s successful rehabilitation work!

Thinking of volunteering? Leela’s story offers an honest and uplifting look at daily life at Nyaru Menteng, and why she’s already planning to return!
This trip was hard work in places but so, so rewarding! The activities are varied, interesting and really benefit the Orangutans which you get to see on an almost daily basis after day 5 when you have your second Covid test. Really well organised from start to finish and the BOSF staff are very welcoming and friendly and everything is explained in great detail. Support from The Great Projects team before I left was superb! You will get the chance for some awesome photos too which will remind you of your great trip. I cannot recommend this trip highly enough, so if you want to do something absolutely amazing then book this volunteer holiday soon.
It was a pleasure to work alongside the members of the BOS team to support the orangutans. The program was well-balanced and organised to provide an excellent range of activities and experiences. Having Niamh and Matt to provide information and support was an added bonus.
An Unforgettable Experience at Nyaru Menteng Orangutan Sanctuary Volunteering at Nyaru Menteng was truly an amazing and life-changing experience. The work was hard at times, but incredibly rewarding – every effort felt meaningful and impactful. The volunteer coordinators, Matt and Niamh, were exceptional hosts: patient, encouraging, and fully committed to giving the orangutans the best possible life. Their passion and dedication were inspiring. Accommodation was clean and comfortable, and we were very well looked after with plenty of good food. It was wonderful to spend time with other like-minded people, all working together on a project that clearly benefits the orangutans. I’m so glad I booked for a full month – two weeks would never have been enough. The four weeks flew by! Highlights of the trip included visiting the pre-release islands and observing the “toddlers” at Forest School – unforgettable moments that really show the importance of this work. Everyone involved in the project was welcoming and lovely, creating a warm and supportive environment. I would absolutely recommend this experience over any other orangutan programme in Borneo – this is the real deal. I’m already planning to return, as the help of volunteers will be needed for many years...

Best of all was spending time with these beautiful, gentle primates who deserve every chance to live the best life possible, whether through full rehabilitation and release into the wild or lifelong care by the amazing team of vets and technicians at BOS Nyaru Menteng. If you’re considering volunteering, don’t hesitate – it’s an experience you’ll treasure forever. (Show More)
