Program overview

Based in the beautiful town of Argostoli, Kefalonia – the largest of the Ionian Islands – you’ll contribute to the protection of loggerhead turtle nesting areas and green turtle foraging areas in Greece. Working in collaboration with local partner organisations on the ground, our role involves assisting with monitoring and protection initiatives for the loggerhead sea turtles and green turtles of Kefalonia.

You’ll have the opportunity to actively contribute to the preservation of turtle habitats, including monitoring the behaviour of adult sea turtles, assessing injuries, protecting turtle nests and ensuring the safe passage of hatchlings to the water if necessary. 

In the mornings, you’ll be out finding turtle nests, surveying sea grass, or checking on turtle behaviour. Afternoons are for beach cleanups and snorkel surveys. Evenings might involve checking on nests, excavations or helping out with hatchlings. When you’re not working, you can chill out on the nearby beaches or hang at the campsite.

Highlights of the program include the chance to contribute to sea turtle conservation by witnessing the entire nesting process, potential hatchings and engaging in sea turtle research. Please note that this program is observation only; participants won’t touch or handle turtles.

You’ll also get the chance to experience the local culture by:

  • Sampling delicious Greek cuisine with regular opportunities to try local dishes.
  • Diving into Greek nights packed with traditional food, music, and maybe even some dancing!
  • Venturing out on guided hikes to discover the island’s fascinating history and breathtaking landscapes. 

It’s an awesome way to soak up the vibe of Kefalonia!

We’ll provide you with all the necessary training to make a meaningful impact and achieve the project’s objectives. And when you’re not busy with conservation efforts, explore the breathtaking sights of the surrounding area.

GVI has successfully been operating ethical and responsible programs for under 18s since 2012. Treating health and safety as a number one priority, GVI takes extra measures for its under 18 programs. As such, it is also a British Standards 8848 compliant provider. This project has been specially designed for those between 15 and 17 years who are looking to volunteer. Throughout the project, volunteers receive guidance and training from leaders who are experts in their field. These leaders have been carefully selected for their extensive experience and their exceptional ability to mentor and inspire young adults.

Speak to alumni

If you’d like to find out what the experience of joining a GVI project is really like, simply contact us and we’ll put you in touch with one of our many Alumni.

We’ll try to match you to an Alum based on your location, nationality, age, stage of academic career, gender, and program interests. This allows you to gain insights into the experience that is most relevant to you.

Depending on your location you might be able to speak to an Alum over the phone or online, or meet up with them face-to-face at a coffee shop nearby. We also run a series of small events around the world where you can speak to GVI Alumni, Ambassadors and staff members.

Get a first-hand perspective

Meet us


We meet you at the airport.

When it comes to support, we ensure that each participant is provided with unparalleled, 360 degree support, from your initial contact with the GVI Family, all the way through your program, and even after, as you become part of the GVI Alumni Team.

As part of this promise, we will ensure, whenever possible, that one of our dedicated staff will be available to meet you at the airport. In most locations, we also set up a Whatsapp group to help with managing airport arrivals.

We will arrange with you prior to your departure that, should you arrive in the agreed upon pick up window, a member of our staff will be there to welcome you, easily identifiable in a GVI t-shirt or holding a GVI sign and wearing a friendly smile.

This means there will be someone there to greet you as you land, and from there you will be transported to your GVI base to start your adventure and meet the rest of your team.

Your Impact

All of our programs have short-, mid- and long-term objectives that align with the United Nations Sustainable Development Goals (UN SDGs). This enables us to report on our collaborative impact across the world in a streamlined manner, measuring which UN SDGs we are making a substantial contribution to. Furthermore, this will help our local partners and communities measure and visualise their contribution to the UN SDGs.

Prior to your arrival on base, you will be educated about the UN SDGs. Then once you arrive on base, you’ll learn about the specific goals we have in this particular location, our various objectives, and also clarification of how your personal, shorter-term involvement contributes to these.

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.

Our sea turtle and marine conservation program in Argostoli focuses on science-based research and conservation efforts in collaboration with local and national authorities on the island.

We work to safeguard the loggerhead sea turtles and their breeding sites and green turtles and their foraging sites along the coast of Greece. This is done by protecting nests, monitoring turtle activity, collecting data, excavating nests and monitoring seagrass and surveying to record changes. During these activities, you’ll have the opportunity to share your knowledge with international tourists and members of the local community – assisting with developing the awareness of sea turtles.

We assist in the conservation of endangered sea turtles and address many of the UN Sustainable Development Goals, such as Goal 11: Sustainable Cities and Communities, Goal 13: Climate Action, Goal 14: Life Below Water and Goal 15: Life on Land.

Project objectives

Our Ethics

Below is a list of core ethics and best practices we believe are essential to the operation of high quality, ethical volunteer and sustainable development programs. We believe that all responsible volunteer and sustainable development operations should focus upon these principles. If you are considering volunteering, these are some of the key considerations you should question, to ensure that your time and money contributes towards positive change.


We want to constantly develop our own understanding of ethical best practice. In so doing, we aim to provide an exemplary industry standard for other education institutions, international development organisations, and social enterprises. Our Badge of Ethics stands for the drive to always do good, better. Find out more, click on the Badge below.

Our 10 ethical commitments


Locally Driven, Collaborative Projects

We aim to design all our projects in collaboration with local organizations and communities and ensure that they are locally driven.


Clear Objectives & Sustainable Outcomes

We aim to clearly define short-, mid-, and long-term objectives with sustainable outcomes for all our projects.


Impact Reporting

We aim to track, record, and publish the impact of each of our projects.


Working Against Dependency

We aim to build in-country capacity by assisting local organizations in becoming self-sustaining.


Responsible Exit Strategies

For each local organization we work with, we aim to have a plan in place for withdrawing support responsibly.


Clear Roles & Specialized Training

We aim to ensure that every participant is assigned a clear role and that they are fully trained and supported to carry out their work by specialized staff.


Respect for all

In all our actions we aim to respect the skills and efforts of all and seek to protect the rights, culture and dignity of everyone who engages with GVI.


Local Ownership

We work to ensure that credit for the results of any project, along with any data collected, research conducted, or Intellectual Property developed, remains the property of local organizations.


Transitioning from the Orphanage Model

We do not condone and aim to withdraw support of orphanages and residential care centers.


Child and Vulnerable adult policies

We will live by our Child Protection and Vulnerable Adult policies.

Continual Development

As an organization, GVI is committed to striving toward best practice, and to educating both our potential participants, our partners, and the world at large about them. Both the volunteering and sustainable development sectors are increasingly, and rightly, under scrutiny. Many recent local and global articles highlight poor practices and questionable ethics. GVI is widely recognized for striving to apply global best practice in the volunteering, education and sustainable development sectors throughout our operations by reputable organizations such as ChildSafe.

However, global best practice is always evolving and we dedicate both time and resources to engage with internationally respected experts and learn from the latest research to ensure our programs both fulfil their potential to create maximum positive impact, and minimise their potential to create unintentional negative impact. Along with and as part of the sustainable development and volunteering community, we are constantly learning and applying this learning to practice. We do not always get everything right, but we seek feedback from our community members, partners, participants and our staff, and react accordingly. We know are already doing a great job, and feedback we have received confirms this, but we aim to do even better and are continuously refining our operations to improve upon our already excellent reputation.

Program ethics

No orphanage programs

We don’t support or allow participants to work in institutional residential care facilities, also known as orphanages. We partner with ReThink Orphanages and Freedom United.

Learn more
Child and vulnerable adult protection policy

Our Child and Vulnerable Adult Protection Policy requires all our staff and participants to complete a criminal background check and to learn why you shouldn’t reveal a child’s identifying factors in photographs. We support the ChildSafe Movement.

Learn more
No medical volunteering

We don’t offer any programs where our participants engage in medical treatment. This is because our participants aren’t typically qualified to do this work and would therefore not be able to do this work in their home country. Our participants only assist with public health programs.

Learn more
No disability support programs

We don’t offer any programs where our participants work directly with people with disabilities. This is because our participants aren’t typically qualified to do this work and would therefore not be able to do this work in their home country.

Learn more
Aligned to local objectives

Each one of our initiatives is aligned to objectives set by a local organisation or professional. Our staff and participants work to support these local actors in achieving their specific goals.

Local employees remain employed

Our participants don’t replace the staff employed by local organisations. Rather, they support currently employed staff with achieving their objectives. Our goal is always to increase local capacity to address local problems.

Local employees remain focused

Participants require training and support to ensure that they carry out tasks correctly. Our staff provide this training and support so that local staff can focus on what is truly important to their organisation at the time.

No entertainment-based activities

We don’t support the use of wild animals for entertainment purposes. This includes riding animals, having them perform tricks, feeding or bathing them or getting close to them to take photos

No orphaned animal sanctuaries

We don’t encourage, support or allow the rearing of “orphaned” wild baby animals kept at a “sanctuary”. The conservation value of these types of programs is negligent and would only ethically be used in extremely rare cases

Guidelines for touching or movement restriction

When wild animals are restricted for conservation purposes we follow the guidelines of Fair Trade in Tourism South Africa (FTTSA), approved by the Global Sustainable Tourism Council.

Animal welfare guidelines

We ensure that the Five Freedoms of Animal Welfare are followed. These include the freedom to express normal behaviour and freedom from distress, discomfort, hunger, thirst, fear, pain, injury or disease.

Local community empowerment

We ensure that conservation efforts are also always locally led, that community needs are front-and centre of any conservation effort and that our participants, projects and partners work to increase local community engagement in local conservation efforts.

Learn more
No veterinary programs

We don’t offer any veterinary programs or animal rescue and rehabilitation programs. We don’t allow participants to do any work they would not be able to do in their home country.

Parent Info

‘If only every student could do this. It changes your life in all the right ways,’ says Chris Heritage, parent of Luke Heritage, one of our teen volunteers who has participated on two GVI programs, one in Costa Rica and another in South Africa.

We are a parent-run organisation that is incredibly serious about health and safety, and increasing the impact, as well as the long-term career benefits of our programs. Our programs help young people develop the skills to select a career path that is personally fulfilling, and live a life aligned to the well-being of our planet and the global community.

GVI is a proud member of the Gap Year Association.

Ken and Linda Jeffrey, whose son Sam volunteered with GVI in Thailand, talk about how the experience affected Sam. He also went on to volunteer with GVI again in South Africa. ‘I know it sounds like a cliche but in a sense, he did go away as a boy and he came back as a young man. Both of us could recommend GVI without any hesitation to any other parent thinking about exploring an opportunity for their children to explore the world and to see different parts of it.’

Support & Safety

We won’t sugarcoat it — traveling abroad is usually a complex process that carries an element of risk. But this is exactly why we’re passionate about providing extensive support throughout the process as well as the highest safety standards during the in-country phase. We believe that volunteering abroad should not only be impactful, but an enjoyable experience that carries as little risk as possible. This is exactly how we’ve been able to maintain our reputation as the most highly respected volunteering organisations in the sector over the past two decades.
