Samboja Lestari Orangutan Volunteer Project

From £795.00

Work on enrichment with captive orangutans and sun bears at the world renowned Samboja Lestari rescue centre.



Project Description

This project is located at the Samboja Lestari Orangutan Sanctuary in Borneo and it gives you the chance to work on enrichment ideas for some of the 200+ orangutans that reside at the project site.

The main aim of this project is to assist in orangutan rehabilitation. By helping with enrichment making, husbandry and small construction projects it means a lot of the staff can be used in areas such as forest school and nursery where they can help teach the young orangutans the skills they need to survive in the wild. This means that they can be released quicker and still have a good chance of survival in the wild.

This project has helped to release a large number of orangutans back into the wild and this is due to the success of the rehabilitation process that takes place at Samboja, and the release sites which are secured by BOSF Indonesia, the charity partner of the project.

This project is perfect for anyone who wants to completely understand orangutan conservation and work alongside people who manage every aspect of rescue, rehabilitation and release.

Why This Project Needs Volunteers

Volunteers on this project help to work towards the rehabilitation and eventual release of the Orangutans and Sun Bears living at the project site. As there are always new animals being bought into the site, it is crucial that there is a steady stream of volunteers to help with enrichment, husbandry, and general sanctuary upkeep.

Due to the volume of animals needing to be looked after at this site, and the limited space available, unfortunately a number of Samboja's animals have to be kept in cages. This is far from ideal, and the project continues to develop and build as many outdoor areas for the animals as possible, but this does require a lot of man power and funding – which is why your participation is so crucial!


Day 1 - The Adventure Begins:
You will arrive into Balikpapan Airport in Kalimantan, Indonesian Borneo. A lodge representative will meet you at the airport arrivals and will transfer you to the eco-lodge at Samboja Lestari. Once settled in you will be given a briefing by Kate your project facilitator.
Day 2 - Induction Day:
After a breakfast buffet at the lodge you will start your induction day which consists of a tour of the entirety of the facility site. Not only will you meet the resident orangutans, but you will also meet the facilities' sun bears and today is a great chance to get to know your fellow volunteers.
Day 3 - Orangutan Enrichment and Husbandry:
Today you will begin your project work at Samboja Lestari. The group is usually split in two with half spending a whole day working on creating enrichment items for the orangutans and assisting with husbandry and the other half doing the same for the sun bears.
Day 4 - Project Work with the Sun Bears:
After breakfast the group will reverse roles, with those who helped with the orangutans now working with the sun bears and vice versa. There is also the opportunity to help feed the orangutans on the islands for some, but please note that everyone will get this opportunity during the project.
Day 5 - Forest Walk:
For a change of pace and a chance to learn, this morning you will take part in a forest walk with members of the orangutan release team and a botanist. During this walk, you will learn about the flora and fauna resident here as well as the food that the orangutans like best. The afternoon is spent working on enrichment for the orangutans, and with over 200 at the centre, volunteer help is crucial when ensuring that each orangutan gets an enrichment item!
Day 6 - Orangutan Enrichment and the Night Market:
Today will be another orangutan day, but to ensure the great apes remain stimulated you’ll be making a different type of enrichment for them. You may also help with leaf collection as these are important in helping the orangutans make their nests. Tonight you will have the chance to visit the local night market and we recommend trying some of the amazing street food whilst there!
Day 7 - Morning to Relax & then a Boat Trip:
Today you will have a relaxed morning off – doing as you like (a lie-in may be needed)! In the afternoon, you will be able to go on a fantastic boat trip along the Black River. This boat trip is a fantastic chance to see the iconic proboscis monkey and a typical Indonesian fishing village, so make sure you bring your camera along with you.
Day 8 - Tour the City of Balikpapan:
Today you will be able to spend a full day in the city of Balikpapan. You will be able to visit the local craft market, have a delicious lunch and buy anything you want or need from the local shopping mall.
Day 9 - Another Orangutan Day:
After a short break from orangutan activities, today you will be back working with the apes. You’ll be assisting with making enrichment and leaf collection, and you may also be called upon to help with some construction tasks and site maintenance if it is required!
Day 10 - Canopy Walk in the Rainforest:
Today is your time for adventure by means of 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 native flora and fauna.
Day 11 - 12 - Project Work with the Orangutans:
Day 12 will be the final project day for 2-week volunteers, and the last chance to work alongside the orangutans assisting with anything that needs to be done. In the evening you will have time to speak to the facilitators, view a slide show from your stay and if you fancy, enjoy a few drinks as a group before transferring to the airport the next day.
Day 13 - Final day or continuing with Project Work:
This is departure day for those volunteers on the two-week project. After a fond farewell you will be transferred to Balikipapan Airport for your flight home or onward travel plans. If you are staying for a month you will be engaged in an afternoon activity before having the opportunity to once again visit the fantastic night market.
Day 14 - Project Work or rest:
All 4 week volunteers will either continue with project work at the centre or have a rest day.
Day 15 - 26 - Project Work and Final Day:
For those volunteers staying for a month, project activities will continue in the same style as above for the two-week itinerary with new volunteers arriving on day 15 to join you.
Day 27 - Final Day:
This will unfortunately be the final day for all volunteers, with transfers arranged to Balikpapan Airport for your onward travel plans.

What will I be doing?

Your main activities whilst volunteering with orangutans at Samboja include husbandry, enrichment, forest plantation, 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.



You’ll head over to the orangutan islands to observe these great apes and collect vital behavioural data on them whilst also monitoring their health and general well-being. You’ll do this by completing a circuit of the islands on a small boat, offering a great chance for some beautiful photographs. Just make sure you don’t drop your camera in the moat!



Whilst on the project you will have the chance to create enrichment to stimulate and benefit those orangutans resident within enclosures, whilst also helping to encourage natural behaviour. Creativity is encouraged here, so if you have an idea which you think the apes would enjoy please put it forward! You will also be preparing the food and delivering this to the orangutan islands.



Some of your time will be spent cleaning the orangutan cages and the fruit store where food for the orangutans and sun bears is prepared. You will also take part in leaf collection (for the orangutans to build their nests,) and this will involve regular treks out into the jungle - make sure you have packed your walking boots and are ready to really get stuck in!

Construction and Maintenance

Construction and Maintenance

You'll be helping with any construction or repair work which may need to be done depending on the needs of the sanctuary. Please note that maintenance and construction are on-going tasks at the centre, and always require volunteers to help out. You may be involved with the building/maintenance of orangutan cages, the maintenance of the rainforest environment and the upkeep of the sunbear enclosures. There is always work to be done!

Working with the Sun Bears

Working with the Sun Bears

You will also be able to work within the sunbear area during your time here, where around 50 sunbears reside. Helping with enrichment and general enclosure maintenance will be the main activities you will be involved with whilst working alongside these magnificent bears - one of the world's rarest bear species.

Canopy Walk

Canopy Walk

This is a very popular excursion from the centre! You will have the opportunity to walk high up in the forest canopy, keeping your eyes peeled for all kinds of fauna and flora. There may even be the chance to spot a pair of singing gibbons if you are lucky! This is a fantastic way to appreciate the diversity of the Bornean jungle, and something not to be missed.

River cruise

River cruise

A wonderfully relaxing afternoon is spent on the black river. You will board a local boat and travel along the winding river in search of the endangered proboscis monkey, famous for its oversized nose. During your journey you will travel through a local fishing village, which will offer you the chance to see how local people live, and then you'll travel briefly out to sea where you will watch the sunset.

Sebastien Durelli - 2017

The first time I look in the eyes of an orangutan it was a very emotional moment for me. I remember very well what was in my mind in that particular moment: orangutans are like us but pure. I was amazed by the people working there and the coordination of Kate together with Sam and Wik!

Holly Dibden - 2017

I will always remember going around the islands on the boat whilst enrichment was given out - seeing one of the female orangutans using the enrichment bamboo as a cup to drink from the moat, amazing!

Kerry Gourley - 2017

It was fantastic getting to see the individual personalities of all the orangutans. Loved every minute of it! We were also lucky enough to be there when 10 orangutans were heading off to a new forest school that would put them one step away from being released.

Sarah Gillett - 2017

I loved everything! I guess if I had to pick one moment it was being so close up to an orangutan for the first time, looking into his eyes and being overwhelmed by the wisdom he seemed to have. The project is one of the best things I've ever done in my life.

Sharon Lynne (Tevet) - 2017

Whatever task it was, I found myself being immersed by this tremendous urge to be involved with all my heart and soul. You can’t help that…. You hear the sounds of the orangs constantly calling out. You become part of this wondrous move to save the now critically endangered orangutan which I will always be involved with – I will go back again. I urge you to do the same. It’s life changing!

Marion Franke - 2017

It is hard to choose just one favourite moment as the whole stay was just a wonderful and enriching experience. Being able to spend so much time observing the orang-utans and helping to make their life at Samboja as natural as possible in a group of like-minded people has been one of the best experiences ever. I would like to give a big thank you to everyone at the Great Projects from the staff here in the UK and particularly to Kate and her team on location. Kate is an incredible person and plays a big role in making this such an amazing experience.

Simone Harris - 2017

The memory that will stay with me forever is connecting with a 4-year-old orangutan named Choccie. She had been rescued following a machete attack the previous year.

Katherine Spooner - 2017

Probably seeing the orangutans on the islands from the small boat, but everything was excellent. Also, the boat trip down the black river was brilliant! Kate Sam and Wiwik were excellent. they work so hard, are so motivational and great fun, always smiling!

Kelly Pring - 2017

The volunteer coordinator and all the others working on the project were amazing and do a fantastic job of making you feel welcome. Couldn't have asked for any more than they gave.
