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.

Five rescued orangutans are about to return to the wild in Borneo after years of rehabilitation and preparation. Discover their incredible journeys and what it takes to survive in the rainforest once again.
UPDATE | May 2026
Over the past few weeks, volunteers have worked incredibly hard to construct and install two handmade hammocks per enclosure, and their efforts are already making a real difference. To further enhance these spaces for unreleasable orangutans, additional enrichment items have been purchased with the support of our volunteers and will soon be installed to encourage climbing, nesting, and natural behaviours!
This was an extraordinary opportunity to delve into the amazing world of Orangutans, not as a mere tourist but as an active partner. Stef and Mel did a wonderful job of including volunteers in the hands-on activities so I felt an important part of the team. The highlights are many including learning about, making and especially giving the enrichment creations to the Orangutans and watching them figure them out, each in their own unique way. Learning how to safely use a machete to harvest leaves for the Orangutans to make their evening beds was empowering. Contributing to the future sanctuary islands by planting saplings felt impactful. I loved being able to watch the Orangutans in the forests on their pre-release islands in the relaxed atmosphere from the boats. By far the most unique and my absolute favorite experience was observing the special comraderie and playful shenanigans of the young Orangutans in Jungle School. This is unique to Nyaru Menteng and was a part of the reason I chose this project. Visiting with the veterinarians , the technicia, the baby sitters to the orphans and other Nyaru Menteng and Borneo Orangutan Survival Foundation (BOSF) staff reinforced that we can make a...

It was a privilege to work alongside so many dedicated individuals and I look forward to a return visit!! Practical issues: Food was delicious: lunch and dinner were prepared for us by a wonderful local cook with good variety and great flavor. My favorite was ayam serundeng lengkuas chicken! There were many breakfast options to make yourself. Warm to cool showers were wonderful to combat the hot days. Sleeping arrangements were comfortable with mosquito netting available. Mosquito prevention is a must. (Show More)
Where to start? What a fantastic experience from start to finish (from first making the booking through to leaving the project at Nyaru Menteng). The time spent watching, supporting and engaging with these magnificent animals was humbling-I laughed and cried multiple times! As a solo traveller, heading off on my first long haul flight, Mags and the team were really helpful and supportive-suggesting flights routes, helping with blood tests/vaccine information and answering any queries really promptly. We were met at the airport by a very cheerful, welcoming Melda (part of BOS) who wasn't really sure what to expect (due to travel disruptions caused by the USA/Iran war which had just started). She took us to the sanctuary where we were met by Stafano (The Great Projects) who took over the reins and got us settled in. He was superb and really went beyond, to make sure everyone got the best out of their stay. From there on in we were really well looked after. It was busy with a cleverly arranged, varied programme which got you actively engaged from the get go. From handling power tools and machetes; preparing enrichment activities; meeting the long-term orangutan residents; boat trips to visit... Where to start?

Hot and sweaty but great fun and incredibly uplifting-with delicious meals provided twice a day, courtesy of Mama Mona! Yes it is incredibly sad that there is the need for such facilities but what is being done is remarkable. All the staff were totally dedicated, knowledgeable and committed to giving these orphaned (or infirm) orangutans the very best of care and the chance of a full and natural life. I would absolutely recommend it to anyone who is toying with the idea. The whole process was so much easier than I expected and the experience much more than I could have hoped. From thinking that I wouldn't go back (often its not good to revisit something!), the longer that I am home the more I think that I will return. Simply-I miss it!!! Thank you, GP, for the opportunity! (Show More)
Going on this trip had been a dream for me for twenty years and to be able to visit Nyaru Menteng was the icing on the cake! I had to postpone my trip twice before I finally got there and Mags was wonderful in managing all the uncertainty. Stefano, Melda, Mama Mona and all the staff were wonderful. We were looked after so so well. Top tip (that I didn't do!) is to make sure you're relatively fit and strong - the heat and humidity take their toll. But Stef was super kind and understanding, and went above and beyond to ensure we all worked at our own pace and that we all had a super time. PS, watch out for ant nests when leaf collecting!
