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. For more information, please view our article on hands-on contact with orangutans.

UPDATE | Sep 2026
The island orangutans got a new enrichment challenge this week. Volunteers filled natural reed bags with leaf parcels, fruit and treats, then watched as the orangutans quickly worked out how to get inside. Three days later, some were still carrying their bags around, dunking them in the water, using them to carry food and even wearing them on their heads!

Gabriella shares her experience volunteering with orangutans at Samboja Lestari in Borneo, from sun bear care and enrichment to daily orangutan conservation work!
UPDATE | Aug 2026
Kikan and Papa have returned to the islands together. So far, Kikan seems a little curious about her new companion, as Papa is already being his usual grumpy, dominant self, breaking branches and making his mark. The pair have already been putting the new platform to the test, too. Built by our volunteers last month, it looks like it’s already received the orangutan seal of approval!
Volunteering at Samboja Lestari was incredible - it is much more than just a holiday. We did lots of hard but manageable work and grew together as a group quickly! The food was really yummy and Kate was very kind, funny and good at instructing us and keeping us motivated. The accommodation is basically a hotel and very clean and comfy. There’s even massages available.
Oh my gosh I have no words. I have only been back home from this wonderful experience for over a week now, and let me tell you - it was truly- life changing. Everything about this experience was a highlight, from simply being on the planet with these amazing animals. Having an Orangutan look directly into your eyes, and you into theirs is simply something i cannot describe. It was amazing as a human, to feel like somehow I was able contribute, even in a small way, to the wellbeing of these majestic animals. The leaders Kate, Wik and Aril, were beyond anything I could have wished for. Their knowledge, kindness, patience, wisdom and generosity in allowing us into their world and sharing this experience with us was something I will never forget. Forging beautiful friendships with a group of people that I had just met . I came home with a full heart of gratitude, a deeper connection to mother earth and these incredible animals, and an experience that will stay with me forever :)
We had a fantastic experience, Kate was our project coordinator and her and her team were so well organised. Every evening she would run through the itinerary for the following day, including how the group were to be split up for different tasks etc. During the 12 nights we had really varied activities, from collecting leaves for enrichment, preparing different enrichments, building a feeding platform, helping to lay a concrete path to removing silt from the river bed to increase the depth of the water. We initially worked with the sun bears until our second covid tests proved negative whereby we were able then to work with the adult orangutans living in the sanctuary. Kate and her team were really supportive, given guidance and had lots of knowledge about the sun bears and the orangutans. The group we were with, were really great, everyone worked well together and we had lots of fun whilst feeling really thankful for being able to give some care to the sun bears and orangutans to help make their lives better. The lodge was very comfortable and we had superb food, best food we have had on any of the other volunteers experiences we have...

We did feel part of a large family of like minded people. One of the best volunteer projects we have been on. Highly recommend this - Kate is definitely the best project coordinator we have had.
