We focus on something different that not only offers a conservation service and rehabilitation of wildlife but to work in coordination with communities originating in the area because they are carriers of ancient wisdom that remain unpolluted by the technology, consumerism, and materialism of Western society.



icone accommodation


Volunteer's accommodation is included in ONCA’s fee. Living conditions in the ONCA camp are quite rustic. We have 3 cabins (indigenous style). There is a dormitory with 6 bunk beds which can accommodate for 12 people, and also some private huts for people who are staying a longer amount of time or would like some more privacy such as couples etc. We provide sheets, pillows and mosquito nets but recommend bringing sleeping bags as it can get cold at night. 

icone meals


The food in ONCA is mostly vegetarian including breakfast, lunch, and dinner. All meals are provided for, breakfast is simple being 2 pieces of bread, butter, and jam, tea or coffee. If you need more for your diet we recommend buying anything extra you may need in town. We all take turns cooking lunch and dinner and we pride ourselves on our volunteers being extremely satisfied with the food. Don’t worry if you aren’t a good cook! We like to experiment.

icone schedule


As we are hard workers and appreciate when volunteers arrive ready and willing to work hard. We understand that it could become difficult for people not used to living in the environmental conditions of the Bolivian Amazon. Usually, volunteers work from Monday to Friday + Saturday or Sunday (six days a week). Everybody gets one day off a week, usually Saturday or Sunday. We are flexible and open in determining which day volunteers would prefer to have off.

icone fees


Because we do not receive any grants or help from the government, volunteers must only cover the cost of food, accommodation, and derivatives. Costs are $50Bs/night that makes up a common support fund. The Approximate exchange rates are $1 USD = $6,80Bs or 1€ = $7,90Bs. You also will be asked to pay a My Proext's administration fee when you are doing your application.




field volunteering

The activities you will develop as an ONCA’s field volunteer can vary depending on how long you will stay here with us:


If you stay for one week you will mainly be doing general construction and maintenance. Support in the construction, simple labor and transport materials. Making of trails and taking care of trails, care of boundaries and support in the garden, among other work. You may be permitted to work in the quarantine if we have animals that have just arrived.


If you stay for 2 weeks you will have the opportunity to work with the spider monkeys and the coatis, taking them for walks through the jungle on trails, preparing meals and feeding them. You will make enrichment tools and devices for the animals, clean maintenance areas and work in the quarantine area. Also, people with knowledge in bio gardens are helpful, as we want to be able to produce as much organic food to feed our animals and people as possible. The people of the indigenous community may ask us for help in any number of activities such as helping in construction, harvesting fruits or plants, clearing trails, or helping in the school. 


If you stay for 3 weeks or more you will be trained as a caretaker. The volunteer, after training, will have the opportunity to support the general work and care of wildlife of the Spider monkeys, Coatis, Night monkey, Squirrel monkeys and Capuchin monkeys. That is, depending on the time spent, cleaning areas of management, food preparation for animals, observation, behavioral studies, making enrichment to keep the animals interested and make them search for their food. Help to socialize the monkeys to create a strong group.


If you are a veterinarian and wants to work with it, the minimum stay is 5 weeks. It is preferable that the vet has experience with wildlife (primates). The vets will need to have an interview (via email or WhatsApp). After a trial week of the normal 50Bs daily contribution paid by the vet, if the trial is going well, the organization will cover the costs of the veterinarian (meals and accommodation) for the rest of their stay.
