Elliot Peacock, 14, was killed while on a trip to the Italian Alps.
The teenager, from Newton Mearns, East Renfrewshire, was one of 40 Eastwood District Scouts enjoying a nine-day break when tragedy struck.
On Friday relatives and friends will gather to celebrate his life at a thanksgiving service at Newton Mearns Baptist Church.
The service starts at 2.30pm and everyone who knew the youngster, who attended Eastwood High School, is welcome to attend.
Elliot's parents Colette and Scott paid tribute to their only child, calling him the "loveliest son we could possibly have wished for".
They said his "joyful presence will be missed so very much".
Elliot died on Sunday June 29 after he jumped into a pool at the Lillaz Falls, about 5000ft above sea level, in the Gran Paradiso National Park.
As the Herald previously reported, tributes have flooded in to the teenager.
His friend James Hay, 14, said: "He was a really funny guy and he made everyone around him happy."
Facebook users are continuing to leave messages on a specially dedicated page of the social networking site, entitled 'Elliot Peacock will always be remembered'.
