Inspired by the International Baccalaureate’s Creativity, Activity, and Service program, CAS Trips aims to make a genuine, sustainable impact through transformative cross-cultural experiences.

We recognize our responsibility as educators and seek to harness the power of experiential learning to inspire students while bringing long-term benefits to the communities and environments in which we operate.

Destination Development

CAS Trips comprehensively research each destination, identifying key Sustainable Development Goals (SDGs) that communities are striving to achieve.


We contact and nurture links with grassroots charities and Non-Governmental Organizations (NGOs) who are working to tackle specific goals.

Activity Development

CAS Trips work closely with charities to create impactful Service Challenges that will give students an exciting hands-on experience, but crucially also fulfills a genuine need.

Sustainability means many things to us at CAS Trips – which is why we use the 17 UN SDGs to  inspire and guide the actions we focus on in our programs. The SDGs are also used as a lense to challenge students to translate their on-trip experiences by developing long-term project ideas during our CAS Project Challenge.

Everywhere CAS Trips goes, we aim to ensure that we are creating a greater global impact through local actions. From our work preserving cultures and supporting local economies to striving to become carbon neutral, we are taking our sustainability seriously. 

Here are some experiences students can expect when embarking on a CAS Trip:

Don Carlos’ Organic Farm

Through long-term partnerships with local non-profits located in the Carmen de Viboral, Colombia, CAS Trips enables students to partake in service-learning impact projects alongside the local communities. Students learn about the challenges of organic farming by taking part in daily tasks while preparing for a cooking challenge, leaving them with both special memories and new perspectives.

Homeless Service Challenges
Czech Republic

In collaboration with Pragulic, students take a walking tour led by a recovering homeless guide before being challenged to plan, cook, and deliver a fresh meal to a local shelter. They then have a challenging fundraising opportunity, which has resulted in over €3.000 donated towards health insurance, rehabilitation treatment, and English classes for the local homeless population in Prague.

Compassion Projects

Student groups who visit Bhutan opt to fundraise before their trips and have the opportunity to meet the communities and contribute towards the projects they are supporting. Most recently a group of students stayed with locals in Mendegang village and raised funds for the building of a much-needed toilet block for the local school. Read more details in this project report.

We travelled very Close To Home; to Samso Island. Approximately 4 hours sailing, and we took a train – it’s amazing because you don’t have to travel that far, you don’t have to use a lot of fuel on airplanes. You don’t have to do all that, because what is really important is that we are all together. 

We are dealing with various interesting CAS Projects. And in the end what I see is a crowd of very happy students who are discussing things that are meaningful, and that’s what matters.

We acknowledge that we must urgently respond to the climate crisis which is why we declared a climate emergency with Tourism Declares in April 2021. Later that year we – alongside many other travel organizations became a launch signatory of the Glasgow Declaration: A commitment to a decade of climate action agreeing to these five commitments:


Measure and disclose all travel and tourism-related emissions.


Set and deliver science-based targets to accelerate tourism’s decarbonization.


Restore and protect ecosystems, supporting nature’s ability to draw down carbon.


Share evidence of risks and solutions with all stakeholders and our guests.


Ensure organizational resources and capacity are sufficient to meet objectives set out in climate plans.
