Orangutan And Sun Bear Conservation

Orangutan And Sun Bear Conservation

Orangutans And Sun Bears in the heart of Borneo's rainforest

Situated with the Borneo tropical rainforest, this is one of the best volunteer placements in the world to see orangutans. The centre is home to 150 orangutans, 72 sun bears and other rescued animals..

As an Orangutan Program Volunteer, you are a key part of our enrichment and welfare program. Enrichment programs are vital for captive orangutans, teaching them how to forage for food, build, modify and use tools, increase agility, and develop skills to survive in the wild. Take this opportunity to leave a long-lasting impact on Indonesia’s wildlife, working hard to provide a meaningful future, not only for animals at the centre but also for the region’s wildlife for many years to come.

“An unforgettable experience. The enrichment work opened my eyes to how much thought and care goes into preparing these animals for release.”
— O2E Volunteer, Samboja Lestari

Volunteers support the daily care and wellbeing of rescued orangutans and sun bears at the centre. Many of these animals have come into care due to injury, illness, habitat loss or conflict with humans, and your role helps create a safer, more enriching environment for them.

Your days may include preparing food, cleaning enclosures, creating and providing enrichment, and recording animal observations for the local team. These practical tasks may seem simple, but they form an important part of each animal’s routine, comfort and behavioural wellbeing.

By contributing your time and care, you help improve the daily lives of these remarkable animals while supporting the long-term work of an experienced conservation team.

This is an ethical, non-contact program. Volunteers do not handle infant orangutans or enter quarantine areas. All activities are guided by BOSF’s strict animal welfare and safety protocols.

olunteer activities vary from day to day, depending on the needs of the animals and the priorities of the local team. Flexibility is important, as planned tasks may change at short notice to support the wellbeing of the orangutans and sun bears in care.

Your activities may include:

  • Creating enrichment for sick, non-releasable and rehabilitating orangutans and sun bears
  • Observing orangutan and sun bear behaviour
  • Assisting technicians with cleaning outdoor yards and care areas
  • Helping to build feeding platforms or repair animal habitats
  • Foraging and cutting leaves, browse and food for the animals
  • Travelling by boat to orangutan island to observe feeding
  • Assisting carers with cleaning the orangutan islands
  • Joining night-time spotlight walks, where available

Volunteers have one day off each week to rest and explore the local area. Optional activities may include the canopy walk, traditional markets or a Black River proboscis monkey cruise.

Mornings at the centre often begin with the sounds of the rainforest — orangutans calling, birds moving through the trees and local wildlife waking around the lodge. Volunteers usually start the day with a fresh, locally prepared breakfast before heading out to begin work at around 8:00 am.

The first work session is often focused on the more physical tasks, such as cleaning, maintenance, building or habitat repairs. These activities are usually completed earlier in the day to avoid the strongest heat.

Depending on the needs of the animals and the local team, you may also head out with carers to assist with morning food supplements for orangutans on the islands. This can provide a valuable opportunity to observe their behaviour at close range, always under staff guidance and without direct contact.

After a two to three-hour work block, volunteers return to the lodge for lunch, usually featuring local Indonesian dishes. There is time after lunch to rest, cool down and enjoy the quiet of the surrounding forest before the afternoon session begins.

Afternoon activities often start between 2:00 and 3:00 pm and may include foraging in the rainforest for leaves and nesting materials, preparing enrichment for the following day, or helping provide enrichment to non-releasable orangutans and sun bears. These tasks support the animals’ daily stimulation, comfort and natural behaviours.

Work usually finishes between 4:00 and 5:00 pm, giving you time to wash off the dirt and sweat of the day, read, relax or take in the view from the observation deck. In the late afternoon, you may see monkeys moving through the trees and hear the orangutans calling as the forest settles.

Evenings are shared at the lodge, with dinner, conversation and time to unwind. Some nights may include games, a movie or a relaxed game of pool with other volunteers and local staff.

As with all conservation work, each day can change. The schedule depends on animal welfare priorities, weather, staff needs and what will be most useful at the centre.

Volunteers need to be flexible, full of enthusiasm and like a good day’s work!

It is important that volunteers are adaptable in terms of what work. they are involved in and the centre will do their best to ensure you are involved in the projects you are most interested in.

Proof of COVID and tetanus vaccination, blood test results for HIV, HEPB, HEPC and TB Test*.
Note: If you are coming from a Yellow Fever endemic country, you’ll need Yellow Fever Vaccine as well.

The work takes place in hot and humid conditions and can be physically demanding. Volunteers should be prepared for practical, hands-on tasks such as cleaning, maintenance, food preparation and enrichment support. It can be tiring, sweaty work, but it is also deeply meaningful when you understand how each task contributes to the animals’ daily care and welfare.

This is a strict hands-off program. Orangutans and sun bears at the centre are protected from unnecessary human contact to reduce stress, prevent injury and support natural behaviours wherever possible.

Volunteers must not touch, handle, feed or attempt to interact directly with the animals unless specifically instructed by authorised staff. This includes avoiding human-like communication, gestures or behaviours that could encourage dependency or disrupt their rehabilitation.

Respecting this boundary is one of the most important ways you can help. Your role is not to form a personal bond with the animals, but to support the conditions they need to live safely, naturally and with dignity.

This program runs seasonally between October and March, with a break during the middle of the year.

Programs begin on Sundays and finish on Fridays. You can choose from 2-week or 4-week placements, with set start dates available throughout the operating season.

Because this is a seasonal program with fixed arrival and departure days, availability can vary. We recommend choosing your preferred month first, then checking which 2-week or 4-week placement best suits your travel plans.

Not sure which dates are right for you? Email us any time at team@oceans2earth.org and we’ll help you find the best fit.

You can choose from 2-week or 4-week placements, with set start dates available throughout the operating season.

8am – 4pm, 6 days a week.

Volunteers have one day off each week to rest and explore the local area. Depending on the weekly schedule and local conditions, included experiences may include a canopy walk, a visit to traditional markets and a Black River proboscis monkey cruise.

During program days, volunteers may also have the opportunity to join night-time spotlight walks or travel by boat to the orangutan islands to observe feeding and animal behaviour, under the guidance of the local team.

The on-site accommodation is in a lodge with stunning views of the rainforest. Two volunteers of the same sex will usually share a self contained room with their own small bathroom (toilet and hot shower), however we offer individual accommodation where possible. You can enquire by email for accommodation upgrades.

Communal areas include a pool table, lounge chairs and a viewing deck.

There is free (but unreliable) Wi-Fi.

Meals at the lodge are simple, generous and locally prepared. Most meals include steamed rice with a choice of Indonesian dishes, giving volunteers a chance to enjoy the flavours of the region throughout their stay.

Dietary requirements can usually be accommodated with advance notice. Please let us know about any dietary needs when you apply so the local team can prepare as best they can.

Fresh filtered water, tea and coffee are provided. Additional snacks are available to purchase at the lodge and can be helpful between meals, especially after a physical day in the heat.

The lodge bar also offers beer, juices, soft drinks and a small selection of snacks at an extra cost. At the end of the day, you can settle in with a cool drink and watch the sun drop behind the jungle hills.

I just returned from two weeks of volunteering with the orangutans at Samboja Lestari. As a huge orangutan enthusiast, this was definitely the best experience of my life, and I can’t wait to repeat it! Hard work, touching moments, exciting explorations, great fun, and laughter. I traveled solo, but I found a fantastic group and new friends from all over the world. I would recommend this experience to everyone, of all ages: everyone can contribute according to their own energy!
