Hundreds of people have attended the funeral mass of Colm Ennis, 37, who died on a climbing expedition on Mont Blanc last weekend.
Mr Ennis was from Waterford city and worked as an human resources manager with Amazon in Cork.
His friend Peter Britton, 55, from Co Tipperary was also killed instantly when both men fell in the Dent du Géant or "Giant's Tooth" sector of the Alps mountain range.
Colm had received a Gold Merit medal for bravery after saving the life of his brother Aidan in the Dolomites in Italy three years ago.
Aidan delivered a poignant message about his sibling's courage and humanity at Lisduggan in Lismore Park, Waterford.
Colm was buried at Kilbarry cemetery, after a Guard of Honour with up to 100 Scouts from Waterford and beyond.
The De La Salle Pipe Band led the cortege to Colm's resting place.
St Paul's Parish Priest Fr Pat Fitzgerald yesterday said: "How much our hearts are with Colm's family. He was full of dreams, schemes and projects."
"He was made for life, said Fr Fitzgerald, explaining how Colm lived more than most do "in two lifetimes".
"We pray he has now reached the ultimate summit."
Colm is survived by his parents, Michael and Susan, along with brother Aidan and sisters, Michelle, Linda and Sarah.
Michelle, along with her daughter Ciara, Colm's niece and god daughter, brought up the Gifts of the Eucharist.
