This project offers you the chance to work on enrichment with captive orangutans and sun bears at the world-renowned Samboja Lestari Rescue Centre.
Your main activities whilst volunteering with orangutans at Samboja Lestari include husbandry, enrichment, reforestation, maintenance and construction work for both the orangutans and the sun bears resident here. You will be treated as pseudo-staff whilst on the project, meaning full participation in all of the centre's work.
Below is an example of a typical two-week itinerary. Please note, however, some activities may be subject to change during the time of your stay as they are dependent on weather conditions and the requirements of the project at the time.
You will be accommodated at the stunning Samboja Ecolodge during your time on the project, all built with recycled materials! Each room comes equipped with air conditioning, mosquito nets, an en-suite bathroom with hot water, and a Western-style toilet. Rooms are allocated on a twin-share, same-sex basis (unless travelling as a couple, in which case you will be accommodated together), and there is the option to pay a single supplement ($540 for a 12-night stay or $1,148 for a 26-night stay) to have a private room.
Within the lodge, there’s a relaxed social area where you and your team can switch off after a busy day. With a pool table and an on-site bar, it’s an easy place to unwind and spend time together.
You’ll be fuelled with three hearty meals a day while on the project, all served buffet-style in the lodge dining area. Breakfast includes a varied spread of cereals, eggs, rice or noodle dishes, fresh fruit, and fruit juice. Lunches and dinners typically feature rice with chicken, seafood, mutton or beef, alongside vegetables, with noodles often on the menu. Vegetarian options include tofu and soybean dishes, ensuring everyone is well catered for. (Please contact us before booking if you have a severe nut allergy.)
This project is based at a rehabilitation sanctuary, and there are orangutans and sun bears 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 29-31°C (84-88°F) in the daytime and 24°C (75°F) at night.

You will need to fly into Balikpapan Airport on your project start date, arriving between 7am-6:15pm, with most international flight routes going via Jakarta International Airport (Soekarno-Hatta International Airport) or Singapore. Upon arrival at Balikpapan Airport, you will be met by a project representative in the arrivals hall who will then transfer you to Samboja Lodge. This transfer takes approximately one hour.
If you arrive a day early and stay in a hotel close to Balikpapan Airport, we can arrange your transfer to Samboja Lodge from there.
To join this project, you will need a tourist visa which you can get on arrival in Indonesia. The cost of this visa is approximately US$35.
If you plan to stay in Indonesia for longer than 30 days, you can get a 30-day tourist visa on arrival and then extend this visa for a further 30 days by going to the immigration office in Balikpapan (which we can arrange for you).
We advise that you speak to the embassy in your country to see if there are any requirements for travel. Please note that your passport must be valid for a minimum of six months from your date of entry into Indonesia.
The work undertaken on this project can be quite physical, often in humid conditions, so a moderate level of fitness is required. No skills or experience are required; all that we ask is that you arrive with a commitment to the project and its aims, a passion for wildlife conservation, and the willingness to work alongside your 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 the Covid-19 pandemic, 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.

UPDATE | May 2026
Samboja was full of activity this May, with volunteers helping with enrichment, building new sun bear resting platforms, and a brand-new pathway around the orangutan socialisation cages, giving the technicians better access to deliver food and leaves! Volunteers also saw some orangutan island moves, with Jujun and Androw settling into island 6.

It was amazing, the organization... the logistics, the way each volunteer was taking care of since the first moment of signing up. Kate was an excellent coordinator, she really took the time to explain everything in detail- the good, the bad, and the uncomfortable truths about working with animals and the reasoning they are in these situations. I originally had the expectation to be working hands on with the animals, but she very quickly explain why and the background of the cases. It made much more sense to me. The lodge is lovely, comfortable and the staff and very very friendly. I would suggest other day trips or excursions, I know we are there for work but would also love to explore outside of Samboja. The boat and the canopy walks were nice, but it seemed a little staged. I would love to have a day trip to another city, another local town, just to explore more of Borneo while we are there. The project itself felt meaningful and like we were actually able to contribute to something.
My experience with the Samboja Lestari Orangutan Volunteer Project was fantastic. The organisation from Kate and The Great Projects from before the trip right through to the last day was exceptional, making sure we got everything out of every activity we undertook. As the Coordinator, Kate was amazing with so much experience, knowledge and care to offer, creating an unforgettable adventure for us individually as well as some unforgettable memories as a group. Wiwik and Aril were incredible, guiding us through our activities to support the Orangutans and Sun Bears and sharing their time with us throughout the entire experience. Having the opportunity to observe, learn about and provide support for both the Orangutans and Sun Bears with such an amazing group of leaders, technicians and volunteers is something I will cherish forever and never forget.
I have recently returned from the Samboja Lestari orangutan project with my grandson. We had the most amazing experience! I loved the fact that the days were varied. It was hard work but each day was fun. Our group of 12 volunteers were awesome, we all connected and worked together as a team. My grandson who is 19 enjoyed every single moment, taking away life time skills and new experiences. I live in the U.K, my grandson in Australia. This was a very special time for us, making fantastic memories! I would highly recommend this project to anyone of any age. If you are thinking about doing this project, then go!!
