Slieve Donard

A compact range, they include Northern Ireland's highest peak, Slieve Donard, and a dozen or so other major summits.

Similar walks are also taking place on the UK’s other highest peaks – Scafell Pike, Ben Nevis and Slieve Donard.

A veterans’ charity will also light one at the top of Slieve Donard to coincide with commemorations at the UK’s other highest peaks.

Organizers hoped flames would be visible on the four highest peaks in the United Kingdom, as climbers with gas-fueled braziers ascended to the top of Ben Nevis in Scotland, Scafell Pike in England, Mount Snowdon in Wales and Slieve Donard in Northern Ireland.

Wounded servicemen and women will climb Slieve Donard to light a beacon at the top of Northern Ireland's highest mountain.
