The Paralympic flame created on Britain's highest peak will be used to light a ceremonial cauldron in Edinburgh later as part of a festival celebrating the Games.
'Splinters' of the fire which was made by scouts on the summit of Ben Nevis on Wednesday will then be taken to other events in the capital, Glasgow and Greenock.
The flame will visit the Tramway in Glasgow, Edinburgh Sick Children's Hospital and Meadowbank Sports Centre before a "Flame Festival" featuring a torch procession.
Scouts lit four flames on top of the UK's highest peaks to spark the Paralympic torch relay this week.
The cauldron will be ignited on the Mound beside a giant symbol of the Paralympic Games, known as Agitos, at 8am.
Locog chair Lord Coe said: "Created at the summit of Ben Nevis, the Scottish Flame represents an achievement of human endeavour, which is something that every Paralympian represents."
After the celebrations in the capital the flame will be taken to the home of the Paralympic movement, Stoke Mandeville, before it is joined with the others created around the UK and carried in a 24-hour relay to London for the opening ceremony.
But the relay has been overshadowed by a row over alleged discrimination against disabled Games fans by organisers.
Those trying to book wheelchair tickets or check their availability can only do so by calling an 0844 number costing up to 41p a minute, while able-bodied people can buy their tickets online from organiser Locog without incurring extra costs.
The arrangements have caused outrage among some disabled people who say they have been kept on hold for long periods of time running up large bills before being told there are no seats available.
Wheelchair user Sarah Bard, 32, said: "It is discriminatory towards the disabled. My able-bodied friends can go online and check availability, see when the latest seats become available and buy them with no added charges.
"Wheelchair users, meanwhile, get left with only one option and that costs us extra money."
An online petition has been set up calling for the rules to be changed and has attracted nearly 40,000 signatures.
On its website, Locog says it has created a ticketing process which is "inclusive and accessible".
"It is important to us that people of all abilities can purchase tickets easily," it adds.
