Speak To A Travel Expert
Activities
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.
Itinerary
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.
Day 1 - The Adventure Begins:
Upon arrival into Balikpapan Airport, you will be met by a member of the team and transferred to the project site at Samboja Lestari. After settling in, and perhaps having your first glimpse of the centre's orangutans, you will enjoy dinner and have a chance to relax before getting a good night's sleep ahead of tomorrow's activities.
Day 2 - Induction Day:
After breakfast at the lodge, you will have an orientation from Kate, the volunteer coordinator, before climbing the on-site fire tower, where you will enjoy an incredible view and see all areas of the centre. In the afternoon you will take a trip to head office to meet the staff, before enjoying dinner in the evening and learning all about the history of Samboja Lestari.
Day 3 - Orangutan Enrichment & Husbandry:
Today you will begin your project work by creating enrichment for some of the 112 resident orangutans and collecting leaves and branches for them so they can build their nests. If there's time, you may also get involved in food preparation for the animals.
Day 4 - Project Work with the Sun Bears:
After breakfast, you will walk to the sun bear enclosures as you prepare for a day working with these incredible animals. You will spend today feeding the bears, cleaning their enclosures and creating enrichment for them. In the afternoon your construction skills may also be tested!
Day 5 - City Visit to Balikpapan:
Today you will be able to spend a full day in the city of Balikpapan. You can visit the local craft market, try some local food or simply buy anything you may need for the week ahead from the local shopping mall. You will also enjoy a nice lunch as a group with the volunteer coordinators.
Day 6 - Orangutan Enrichment & the Night Market:
Today will be another orangutan day, and to ensure the great apes remain stimulated you’ll be making a different type of enrichment for them. Afterwards, you will be able to give the enrichment items to the orangutans and see what they make of your work! Tonight you will visit the local night market and we recommend trying some of the amazing street food whilst there!
Day 7 - Enrichment & Branch Collecting:
This morning you'll be helping with any current construction projects, such as building platforms on the orangutan islands. Then, in the afternoon, you will be creating enrichment for the orangutans in an area which overlooks the orangutan islands, offering another great opportunity to observe them.
Day 8 - Morning to Relax & a Boat Trip:
Today you will have a relaxed morning off which you can spend as you like (a lie-in may be needed)! In the afternoon, you will go on a fantastic boat trip along the Black River. This is a great opportunity to see the iconic proboscis monkey, so make sure you bring your camera along with you!
Day 9 - Reforestation & Project Work:
This morning, the focus will be on reforesting an area of degraded land, bringing life back to the area to create a future thriving habitat. In the afternoon, you may help gather branches for nest-making and take part in a construction activity if the project requires it.
Day 10 - Canopy Walk in the Rainforest:
You'll begin your day either working on enrichment for the orangutans or on a small construction project. In the afternoon, you'll be off on an adventure as you go on a canopy walk in the rainforest! You will have the opportunity to walk high up in the forest canopy, keeping your eyes peeled for gibbons and learning about the native flora and fauna from the project staff.
Day 11 - 12 - Project Work with the Orangutans:
These will be your final full days at Samboja Lestari, and you will spend your remaining time working alongside the orangutans. You will continue to create enrichment for them and, if you have not yet had the opportunity, you will take a small boat around the islands to distribute food or enrichment items. This is a great opportunity to see the orangutans up-close and to take some amazing photos! Your final evening will be spent with your group and the project coordinators, as you enjoy your final dinner and a few drinks if you wish.
Day 13 - Final day:
Sadly, today will be your final day and after saying goodbye to the rest of your group and the project staff, you will take a transfer back to Balikpapan Airport in time for your flight home or to continue with your travels.
Durations & Prices
Accommodation
Volunteer Accommodation

Each room comes equipped with fully working air conditioning, mosquito nets and an en-suite bathroom, with hot water and a western-style toilet.
Meals & Beverages
You will have three meals per day provided for you while on this project. Breakfast is a variety of cereals, eggs, rice/noodle dishes, fruit, and fresh fruit juice.

Tofu and Soybean dishes are also provided for vegetarians, and each meal is served as a buffet. (Please contact us before booking if you have a severe nut allergy.)
Project Details
When is the best time to volunteer?
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.
Getting There
You will need to fly into Balikpapan Airport on your project start date, arriving between 7am-5pm, with most international flight routes going via Jakarta International Airport (Soekarno-Hatta International Airport). Upon arrival into 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 will be able to arrange your transfer to Samboja Lodge from there. Please let us know if you would like any suggestions.
Visa Requirements
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.
Fitness & Skills
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!
Vaccinations & Medical Requirements
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.
No Contact Policy
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.

Reviews
Volunteering at Samboja Lestari with The Great Projects is one of the most rewarding experiences I’ve ever had. Supporting the incredible work of the Borneo Orangutan Survival Foundation feels meaningful on every level – you know your effort directly contributes to the care and rehabilitation of orangutans and sun bears who have already endured so much in their lives. Be prepared: the work is hot, humid, and tougher than anything I’ve done before. But every drop of sweat is worth it when you see the animals benefiting from your contribution, or when you catch a quiet moment watching orangutans move through the trees or interact with the enrichment you've made. The sense of giving back is something that stays with you long after you leave. The accommodation at Samboja Lodge is out of this world – beautiful, comfortable, and set in such a special environment. The food is another highlight: three home-cooked meals a day packed with delicious Indonesian flavours. After a day of hard work, sitting down to meals like these feels like a real treat. What truly makes this project stand out, though, is Kate, the volunteer coordinator. She goes above and beyond to make sure every volunteer...

What truly makes this project stand out, though, is Kate, the volunteer coordinator. She goes above and beyond to make sure every volunteer feels comfortable, included, and part of the team. Nothing is too much trouble – even taking requests for a longer walk back just so we could spend more time observing orangutans on the islands. Her energy and warmth tie the whole experience together. This was my second time at Samboja, and I know it won’t be my last. I will return again and again – because once you’ve been part of this project, it stays in your heart. (Show More)
We had a fantastic trip to Samboja. Our volunteer coordinator Kate was amazing, she was very knowledgeable and full of enthusiasm. we did lots of activities from filling in a huge hole on a pre release island for orangutans to making food platforms, cutting down ginger leaves in the forest and making enrichments for the orangutans that were unable to be released due to lack of survival skills as lots were taken from their mothers for the pet trade. The technicians at the lodge that worked alongside us were friendly and encouraging a real team ethos. The trips that Kate organised for the group ranged from a local night market to a forest hike and a river cruise to Proboscis monkeys. I cannot recommend her or this experience highly enough.
I thoroughly enjoyed my fortnight at Samboja. Everybody was very friendly. Kate and the team looked after us really well. The lodge was comfortable and the food was good. Working with the Orangutans and Sun Bears was a real privilege. I ended each day tried but with a real sense of achievement. We did a variety of tasks, from filling sand bags to reinforce a river bank to making jam sandwiches with leaves as part of enrichment. We also got to see a little of the local area visiting the Black River and a night market. It was a great way to see a little of Borneo and do some good. My only regret is that I only went for 2 weeks rather than 4.
