"Sister Ethel Normoyle is the founder and director and she has received many accolades for her incredible work - she was visited by Mother Theresa, Queen Elizabeth and many other famous people, which speaks to the impact of the centre and her leadership ability."
Ms van Deventer said the trip "is the perfect way for the special values students are taught at Rathkeale and St Matt's to be reinforced in a way that they will remember for the rest of their lives.
"I think when they are exposed to such a different culture, physical environment and social dynamic, it will change the way they look at the world."
Natalie Finnigan, marketing and communications manager for the Trinity Schools Trust Board, said the group of senior college students would spend 18 days in South Africa, visiting sites with geographical significance and spending time at the care centre with the staff and members of the wider community.
Trip highlights included a tour of Robben Island, where Nelson Mandela was imprisoned for 27 years, visits to wildlife and game parks, as well as hikes to waterfalls, canyons and caves to study geological formations, Ms Finnigan said.
