From sea to summit make big steps for little hearts as you conquer the highest mountain within the Mournes, Slieve Donard under the guidance of our fully qualified instructors. Whether you take on the challenge yourself or with friends and family, we encourage a real team atmosphere on the hill, walking together and providing encouragement to each other every step of the way. Every step you take will help us to continue to support children and young people diagnosed with heart disease, right here in Northern Ireland.
