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.

I could not recommend this experience highly enough...5 stars do not seem enough. The organisation and communication from The Great Projects was excellent getting us there. Samboja Lodge, the staff, the accommodation was second to none. A huge shout out to Wiwik and Aril as the link technicians with our group and there are no words to describe how brilliant the Volunteer Coordinator Kate is: thoughtful, knowledgeable, kind and funny come close to summing her up, but not really strong enough. And finally, the privilege of working near the sun bears and the orangutans was just awesome, and the best thing I have ever done. If you are on the fence about going, just book it. The best thing I have ever done
I had a wonderful time, a wonderful experience!!! I then realized how much work goes into this project—relentless, tiring, and financially significant. So many men put their heart and soul into it. An example for all humanity!
What a wonderful experience! I feel so lucky to have played a small part in the work at Samboja. The dedication of everyone involved in the project at BOS is so inspiring: real hands-on involvement to make a difference and really help the orangutans and sun bears. Be prepared to roll up your sleeves and sweat.....you will be rewarded by meeting some of the wonderful creatures being looked after by the BOS team. Bravo and thank you - with a special mention to Kate, not only for her outstanding leadership but also companionship (and endless patience).... Kate kept us all going, was always there to guide us, teach us - and also amuse us. Terima kasih, Kate! I really hope to return to catch up on progress in years to come with some of my family.
