Biological Research Volunteer Programs in South America

This experience changed me in ways I never expected. From the moment I arrived, I knew it would be life-changing, but looking back, I can say it was the best experience of my life, and I'm only 22. The local team was truly incredible. They supported me 24/7, and whenever I struggled or faced a difficulty, they were 100% there to help. I couldn't have asked for better people to work with, and I'm so glad to have met them and built real friendships along the way. The same goes for the other volunteers. Living and sharing spaces with them made the experience special and unforgettable, and I came away with countless memories and a lot of laughs. The accommodation was very different from what I'm used to in Western culture, and sharing space means giving up some privacy, but that was part of the charm and I wouldn't change it. The children and the locals touched my heart so deeply that, after my volunteering hours ended, I decided to sponsor some of the children I spent time with from a distance. This experience opened my eyes to how much exists beyond my own borders, both the beautiful and the difficult. The people I met taught me how to smile, how to truly live, and above all, how to be grateful for what I have. Thanks to them, I now know what I want to devote my life to: helping others and making people feel seen and valued. Before leaving, I was nervous about being in a foreign country, far from home, surrounded by people I didn't know, and I worried about whether I would be able to adjust. But that fear faded far more quickly than I imagined. The people I once considered strangers became an essential part of my journey and, most importantly, became my friends.

From the beginning the whole process was seamless and very supportive. Airport pickup, transportation, accommodation, staff, food were first class. They couldn’t have been more helpful. I participated in a teaching program in Kandy, also turtle conservation. Both programs far exceeded my expectations and I left feeling that I had made a difference. Wonderful connections and friendships made with fellow volunteers from all over the world. Life changing in many ways.

I spent six weeks in Ecuador this summer through Beyond Travels, including four weeks living with the Yumbo family near Tena in the Amazon. I still talk about this experience all the time. It continues to shape how I think about food, medicine, land, and community, but what stays with me most is the relationships I developed. Clemente and Elena welcomed me with open arms into their family. I developed relationships with their children and grandchildren, and over time, I felt increasingly part of the family’s everyday life. Being included and cared for in that way meant so much to me. When I think back on Ecuador, I think about the people I miss just as much as everything I learned. My time at Pakarina was also an important part of those six weeks and something I would love to share more about. I arrived with an interest in medicinal plants, agriculture, and community health, and living with the family gave those interests a much deeper meaning. Walking through the chacra with Clemente, I would ask about the fruits, roots, and plants around us, and he would explain what they were, how they were used, and where they grew. Harvesting hearts of palm together made me appreciate the knowledge and work behind a food I had previously encountered without understanding its origins. Some of the conversations that stayed with me most were about Kichwa and the knowledge held within the language. Hearing concerns about younger generations speaking less Kichwa made me think about how plant knowledge is passed down through words, stories, and shared practices. These are questions I’ve continued exploring since returning home. The experience also required patience, flexibility, and a willingness to be uncomfortable sometimes. I had to slow down, listen, and recognize how much I still had to learn. Four weeks offers only a small glimpse into a family’s life, but the relationships we built during that time were meaningful to me. I’m deeply grateful to Clemente, Elena, and their family for welcoming me so fully and sharing their time and knowledge. I returned home with people I hope to stay connected with and experiences that continue to influence my studies and my interest in medicinal plants and healing spaces. For someone willing to participate in everyday life, ask thoughtful questions, and remain open to unfamiliar ways of learning, this experience has so much to offer.

The pre-departure support given was very adequate and I felt very reassured despite me traveling by myself for the first time. Sign up was easy and I definitely recommend volunteering with IVHQ. Staff were very helpful too.

I did an animal care project in Portugal with IVHQ and I'm glad to say it was smooth from start to finish. The application was simple and the team always answered any questions I had about the placement itself or any issues I had with documents etc. Before I left there was a group call with my coordinator and other volunteers I'd be working with which made leaving home alone for the first time less daunting. At the placement I would feed the dogs, clean cages and have loads of cuddles and play time with them! The local team were very friendly and easy to approach as well. I had a great time and really felt like I actually made an impact. I would recommend IVHQ to anyone who would like to volunteer abroad

Participating in ASA's volunteer program was an experience I will cherish for the rest of my life. The jungle at Finca Las Piedras is stunning, and I saw so much wildlife. The trail system is well-maintained and beautiful to explore. The staff is extremely knowledgeable and supportive. While the accommodations are basic, they are clean and safe. I loved waking up every morning to the sounds of the jungle. Supporting the protection of this important ecosystem while learning about the region’s unique wildlife was a life-changing experience. I would highly recommend this volunteer program to anyone considering it.

My time volunteer teaching in Zambia was unbelievably fantastic. I met such lovely fellow volunteers, staff at my volunteer house, teachers and of course kids at my school. The program was really well organised from pre departure to arrival home with plenty of time for sight seeing. I felt so safe in Zambia and received a warm welcome. I felt relaxed at all times and really did not want to come back. I plan to do it all again next year and hopefully catch up with the children a year on in their studies. I'm missing everyone in Zambia!

I Took my first trip alone with IVHQ as a 17 year old last month. It was an amazing first trip where I was supported the whole way and made many friends from all over the world. I loved the volunteering and I learnt so much about the culture. I am already planning my next trip!

Volunteering in Zanzibar was an amazing and unforgettable experience. I had the opportunity to meet wonderful people from different countries, discover the local culture, and take part in meaningful activities that made every day special. The staff and coordinators were always welcoming, supportive, and friendly, which made me feel comfortable from the beginning. I also created strong friendships with the other volunteers and shared many great moments with them. This experience taught me a lot, both personally and culturally, and helped me grow as a person. I would definitely recommend it to anyone looking for a unique, rewarding, and meaningful experience abroad.

My time in Brazil was honestly one of the best experiences I’ve ever had. Living and working alongside the other volunteers made it so much more than just a trip. We spent so much time together, from working in the rainforest during the day to hanging out and getting to know each other in the evenings. I met some genuinely great people who I’ll remember for a long time. A big part of what made the experience so special was Imran. He is a genuinely great guy who made everyone feel welcome and looked after us throughout our time there. His passion for the work and the people around him really stood out, and he helped make the whole experience feel like a community rather than just a volunteer program. I loved being out in the Amazon, learning about the environment and getting involved in biodiversity research, species identification and restoration work. I came away with a much greater appreciation for the rainforest, but also some great memories and friendships that I’ll take with me. I would honestly recommend the experience to anyone who wants to do something completely different and genuinely memorable.

My volunteering experience in Sri Lanka with International Volunteer was truly one of the most rewarding and enriching experiences of my life. From the very first moment I expressed interest in the program, the organization supported me step by step until my departure, making the entire process smooth, clear, and stress-free. The team was always available to answer my questions, provide guidance, and ensure that I felt fully prepared for my journey. Their professionalism, dedication, and genuine care gave me confidence and peace of mind throughout the whole preparation phase. The teaching project I participated in was absolutely wonderful. It was an incredible opportunity to work with enthusiastic students, immerse myself in the local culture, and make a meaningful contribution to the community. Every day was filled with learning, personal growth, and unforgettable moments. I am extremely grateful to International Volunteer for creating such a well-organized and impactful experience. I highly recommend this organization to anyone looking for a volunteer program abroad. Their support, commitment, and the quality of the projects they offer make them an outstanding choice for volunteers. Thank you, International Volunteer, for helping me live such an amazing adventure and for making a real difference in the lives of others while also changing my own life for the better.

I had an amazing experience with IVHQ during the Coastal and Marine Conservation programme in Zanzibar. From the application process to the end of my stay, everything was well organised and I always felt supported. The application process was simple and straightforward, and the IVHQ team provided all the information I needed before travelling. Communication was clear and any questions I had were answered quickly. The pre-departure information was especially useful because it helped me understand what to expect and prepare properly for the experience. Once I arrived in Zanzibar, the local team was welcoming, friendly and helpful. The orientation was well organised and gave me a good introduction to the local culture, the area and the programme. I always felt that there was someone I could rely on if I needed help. The Coastal and Marine Conservation project was definitely the highlight of my experience. I had the opportunity to take part in activities focused on marine conservation and learn more about the importance of protecting Zanzibar’s coastal ecosystems. It was very rewarding to see how our activities could contribute, even in a small way, to the local environment. The experience was not only educational but also practical, allowing me to get involved rather than simply learning about conservation from a theoretical perspective. The accommodation was comfortable and suitable for a volunteer programme. Living together with other international volunteers was also a great part of the experience. I met people from different countries and backgrounds, and many of them became good friends. Sharing everyday life, activities and free time with other volunteers made the experience even more memorable. The meals were another positive aspect. The food was generally tasty, fresh and varied, with a good opportunity to experience local flavours and dishes. The staff were also very attentive and accommodating. I also really appreciated the opportunity to experience Zanzibar beyond the project itself. The island has incredible beaches, landscapes and a unique culture, and having the opportunity to interact with local people made the experience much more meaningful. Overall, I would absolutely recommend IVHQ and the Coastal and Marine Conservation programme in Zanzibar. It is a great opportunity for anyone who wants to combine travelling, meeting people from all over the world and doing something meaningful for the environment. I came home with new knowledge, unforgettable memories and a much greater appreciation for marine conservation. Thank you to the entire IVHQ team and the local staff in Zanzibar for making this such a special experience. I would definitely consider doing another IVHQ programme in the future!

I didn't expect this program would positively impact me so much. My first 2 days were tough, had no internet connection (no idea what's happening to my family), high humidity, mosquitoes, muddy. However, once I got myself "dirty", I started to see the good sides of it. I slept well every night (beds were equipped with mosquito net) and woke up with birds chirping. I learnt how the forest relies on each other and how flood, predators (such as caiman, anaconda) and swamp are benefiting the forest through the explanation of the researchers who worked there. Things that were seemed dangerous or gross turned out to have positive impact to other animals or plants. Activities there were fun though exhausting sometimes. I remember holding a snake and a small caiman for my first time during our night walk! I also remember walking few hours to collect seed. Also, we played volleyball on the last day! It's definitely an eye opener trip for me.

I had the time of my life. At first i was a really scared kid, afraid to even speak and then one night i sat with Sarah, my Coordinator and she let me feel that talking with other people is not that scary even if u have a thick accent. And i’ll never forget that night because it gave me the push to talk with people. Everybody were heartwarming, always listening. The day care was amazing, i cried so hard when i had to leave the school and also when i needed to leave the house it self. Best weeks of my life.

Throughout my placement in Croatia, IVHQ provided me with the relevant help and support needed to make my stay as stress free as possible. I would highly recommend this company and encourage anyone contemplating a placement.

Overall I had an amazing time at the jungle project from the people to the activities itself I have no bad words to say. Emily, Cristobal and Aldho were amazing and made the experience super enjoyable.

My internship at the Salesian Institute Youth Projects pushed me far beyond what I expected, taking me from supporting program logistics to independently running counseling sessions and managing my own client caseload within just a few months. I was trusted with real responsibility early on, from leading a group of 45 adult learners on my own to adapting a therapeutic intervention on short notice for an urgent client referral, and that trust taught me more about clinical work and resilience than I could have learned in a classroom. This experience confirmed that clinical psychology, particularly cross-cultural and community-based care, is exactly the path I want to pursue.

Connect-123 made my experience in Ireland truly incredible. From the beginning, they did an amazing job matching me with a company that fit my personality, interests, and career goals. I couldn’t have asked for a better internship experience. They also did a great job planning weekend trips around Ireland, giving me the opportunity to explore different parts of the country and make unforgettable memories along the way. Overall, Connect-123 made my time in Ireland an amazing experience both professionally and personally.

I was, probably like some of you, a bit sceptical when initially applying due to the low price compared to other organisations. However, the experience I had was absolutely amazing and I have learnt so much about not only myself, but about different cultures and etiquettes. My program manager, Marissa, was absolutely fantastic at answer all of my questions and adjusting any mistakes I submitted onto my application such as flight number and pick-up time. Despite the huge time difference between Marissa and myself, she was able to reply to my email promptly and with extreme care - I was really at ease throughout the whole process and that made the experience a bunch better. Everything on my volunteering was as described on the program guide and there were no surprises when I landed, everything that happened during my week I was prepared for. I would really recommend this company and I want to thank them once more for the fantastic and truly life-changing experience they provided for me.

I had such a wonderful experience in Split! I met so many amazing people from different countries and made memories that I will definitely never forget. The Youth Support program gave me the opportunity to connect with the local community, experience a different culture and grow personally at the same time. The local team was very welcoming and supportive and I always felt comfortable asking questions or getting help when needed. I especially loved the international atmosphere and meeting people with completely different backgrounds and stories.besides volunteering, I had enough time to explore Split, enjoy the beautiful beaches and nature and experience Croatian culture. This experience helped me step outside my comfort zone, become more independent and see things from new perspectives. I’m really grateful for all the people I met and everything I experienced during my time here. I would definitely recommend this program to anyone who wants to travel, volunteer, meet new people and create unforgettable memories abroad. ❤️
