Who Are We?

CAS Trips is an educational tour operator. We tackle the UN SDGs whilst engaging in volunteer projects inspired by the notions of Creativity, Activity and Service. Together with schools, we aim to make a genuine, sustainable impact by taking students on a customized school trip.

CAS stands for Creativity, Activity and Service and is derived from the IB curriculum. 5,000 students from over 70 schools from around the world have traveled with CAS Trips. Together we have completed over 25,000 service hours with local charities and NGOs in various destinations.

Mission Statement

CAS Trips’ principal aim is to Educate, Challenge and Inspire students to become global-minded, conscientious young adults by harnessing the excitement and power of travel to introduce, explore and engage with real global issues in real life situations.













Our Services

As educators and volunteer travel experts, we understand the stresses of organizing student travel for teachers and therefore cater directly to your needs. CAS Trips offers teachers free places on tours alongside planning and executing all-inclusive transport, accommodation, food and customized tours for your school trip. Simply put, we make travel with students easy and stress-free.


CAS Trips offer an all-inclusive travel service. For international transport, we offer group rates via our international travel partners, STA Education Travel. For day-to-day travel within destination cities, we utilize the public transport systems, with all travel passes included. Additionally, when necessary, we offer private transport for day trips and airport transfers.  


We offer two standards of accommodation: Budget or Comfort. The Budget accommodation option refers to high-end, centrally-located hostels with 8, 6 or 4-bed dorms for students and private rooms for accompanying adults. The slightly more expensive Comfort accommodation option refers to mid-range, centrally-located 3-4* hotels, with twin rooms for students and private rooms for accompanying adults.


When we say all-inclusive, we mean it! All breakfasts, lunches and evening meals are included, saving you time and money.


CAS Trips tours stay in the memory of students and teachers for a lifetime. Our highly competent team of university-educated, full-time professional guides all possess fluent or advanced level English, work permits and international police clearance checks.
