Mountain to Climb Hiking Challenge

Join us as we come together to take on two inspiring routes – Fairy Castle & Three Rock in the Dublin Mountains and Claragh Loop in Cork – all to raise funds to help us support families affected by childhood cancer every step of the way.

Every hill we climb represents the strength, determination and courage shown by children facing cancer and the families who walk beside them.

This event is about challenge, connection and community –  pushing ourselves physically while standing in solidarity with those who face far greater climbs and raising vital funds.

From the sweeping views over Dublin City, Dublin Bay and the Wicklow Mountains to the woodland trails and open countryside of north Cork, both routes offer a rewarding challenge and a powerful sense of achievement.

Climb for Childhood Cancer.

Fairy Castle and Three Rock
This rewarding loop from The Gap climbs steadily onto the open slopes of the Dublin Mountains, linking the iconic granite tors of Three Rock with the summit of Fairy Castle, the highest point in the range. The route combines forest tracks, open mountain trails and wide panoramic views over Dublin City, Dublin Bay and the Wicklow Mountains, making it one of the most popular upland walks close to the city.
