Program overview

In the heart of Costa Rica’s Caribbean coast, teens aged 15 to 17 come together for an unforgettable experience. With its lush jungle and stunning beaches, Gandoca sets the stage for an adventure like no other. Our focus is on making a real impact – whether it’s preserving sea turtles, cleaning up coastlines or supporting sustainable farming. Come join our Gandoca crew and contribute to meaningful change!

Teens on this program actively participate in sea turtle nesting projects and contribute to beach cleanups, sustainable farming initiatives and recycling projects.

Throughout this program, teens will receive training, guidance and support from world-class leaders in the field, carefully chosen for their expertise and ability to inspire and mentor young people. This hands-on experience will help participants develop valuable skills such as intercultural competency, teamwork, resilience, self-awareness, and leadership – essential qualities for their future college applications and employability.

In July and August, be ready for long, sunny days. You might encounter some local wildlife like insects and bats, but it’s all part of the adventure. Mosquito repellent will come in handy. Keep in mind, sometimes luxuries like warm water and electricity might be unavailable, but it’s all part of the authentic experience of living in this beautiful place!

GVI has been running ethical and responsible programs for under 18s since 2012. We prioritise health and safety, going the extra mile for our younger participants. We’re proud to meet British Standards 8848. With over a decade’s experience in Costa Rica, we’re dedicated to locally-led projects that prioritise community needs, long-term involvement and local capacity-building.

Upon arrival at their destination, all teen participants are met by a GVI staff member. They offer continuous support throughout their program, ensuring their safety and well-being every step of the way.

Our aim is to educate you on local and global issues, so that you continue to be an active global citizen after your program, helping to fulfil our mission of building a global network of people united by their passion to make a difference.

Kekoldi Indigenous Reserve is a key area for many interlinked conservation efforts as it is home to several species including:


  • Jungle cats like pumas and ocelots. 
  • Peregrine falcons and plumbeous kites Kekoldi is the third most concentrated area for migratory raptors in the world.
  • Thousands of tropical bird, reptile and amphibian species.
  • Species like sloths, tamanduas and kinkajou.


Rainforest biodiversity surveys

We assist the Kekoldi Reserve science team with biological assessment surveys of the three major habitat and forest types in the reserve. We note a wide range of species on our surveys, including the rain frog, red-eyed treefrog, three species of toucan, spider monkey, mantled howler monkey, white-lipped peccary, eyelash palm pit viper and Baird’s tapir (although these are very elusive, so no promises!) Staff and participants walk marked paths in the forest, noting sightings, tracks and vocalisations. Only species identified with 100% certainty can be recorded. The data is shared with KIR, who uses a standardised methodology to monitor the condition of each trail over time. This helps them to understand the health of the local environment and whether their current conservation efforts are working.

Sea Turtle Research

We assist Turtle Rescue Cahuita (TRC) with sea turtle research and protection by patrolling the beach and assisting in hatchery opportunities – using internationally recognised protocols – during turtle nesting and hatching season. The prime time for turtle sightings, including green, hawksbill and leatherbacks, is April/May. For observing adult turtles, March to May is ideal, while May to August offers the best chance to see eggs and hatchlings.

To participate in the turtle project, you’ll need a good pair of rubber boots, thick socks and dark-coloured, long-sleeved, lightweight clothing.

From March to August a team walks the beach each night looking for nesting sea turtles. Depending on the time of year, you might not see a single turtle, or you might see multiple turtles in one night. When a turtle is encountered, different kinds of research activities might be carried out, depending on what stage of the nesting process she is in emerging from the sea, selecting a nest site, digging a body pit, digging her egg chamber to lay her eggs, covering her egg chamber, disguising her nest, or returning to sea. This might include checking for distinctive markings to see if she’s been to the beach before and making a note for future researchers if she returns, tagging her flippers, measuring her carapace, counting her eggs, marking her nest, or checking for abnormalities in the mother turtle or eggs. You might also determine whether any eggs have hatched, been eroded by the sea, been attacked by predators (like raccoons, white-nosed coatis or ghost crabs), or been poached by humans. This information is used to investigate whether any areas of the beach are more susceptible to nest loss. 

Hatched nests are excavated to determine hatchling success and survival rates, the reason for losses in egg development, and the actual status of the nests, including whether or not they were partially or fully poached.

Wild Cat Population And Predation Research

Kekoldi is home to several endangered or vulnerable wild jungle cat species – including ocelot, margay, puma and jaguarundi.

Our research assists reserve authorities and conservation teams to determine the population sizes of each cat species, map out the territoriality of individual cats within each of those species, and identify the availability of prey species in the area and the subsequent effect on feeding behaviour. Direct observations of these elusive animals can be difficult, but the use of remote observation techniques like camera trapping has proven very successful in surveying and monitoring wild cats across large areas of forest.

Bird Research

Kekoldi boasts the world’s third-largest concentration of migratory raptors, with 4.6 million counted from a single point. Notably, it’s a key migration spot for peregrine falcons and plumbeous kites.

We partner with Kekoldi Hawkwatch, studying raptors and predation in the reserve. Monitoring predator health yields crucial data on ecosystem vitality, environmental shifts and guides conservation efforts. Situated within the Talamanca-Caribbean Biological Corridor, the Hawkwatch site offers panoramic views of the biodiverse surroundings, including 59 mammal species, 43 amphibians and over 400 bird species. They’re the second-largest Hawkwatch in the Americas, dedicated to preserving their 6,000 ha sanctuary and educating visitors on conservation importance.

Our work with Kekoldi Hawkwatch takes place during migration season (approx. mid-Feb to mid-May and early Sep to end-Nov) for conducting migration counts.    

Project objectives


GVI Kekoldi’s Long-term Objectives:

1. Increase scientific knowledge of Kekoldi Indigenous Reserve.

2. Increase awareness of the ecological value of the Kekoldi Indigenous Reserve.

3. Build local capacity to support long-term conservation of biodiversity and sustainable community development in Costa Rica.

4. Minimise our environmental impact on Kekoldi Indigenous Reserve and raise awareness of environmental issues amongst participants and visitors.


The best decisions in international development and conservation cannot be made without accurate and up-to-date data or informed research. Our many field teams around the world collaborate with local and international partners to analyse data and draw conclusions. In addition, many of our participants have used research they have collected on their various GVI projects to complete their Masters, Doctorate, or postdoctoral studies. We also run a fellowship program which connects postdoctoral researchers at globally-respected universities with our many sustainable development programs around the world to support their research and ensure continuous improvement of our best practices on base.
