"First time in 9 years coming back to the Mourne Mountains and summitting Slieve Donard again with 4 new peaks to my collection
Overall it was an easy hike so we made a technical decent back to the bloody bridge car park
Also accompanied by my friend attempting this challenge with me " — Tom/Guardian • Dec 19, 2025

"Very windy but fair May weather. Starting in Newcastle, I approached Slieve Donard directly from North via a footpath which can be traced but you have to be careful and always compare with the GPS. After Donard I visited Slieve Beg and began a long but steady descent back to Newcastle." — markorothe • May 3, 2025
"Best weather day in Ireland - sunny and slightly breezy. Trail is well marked, and easier than the other peaks we've hit. We didn't have time to hit Slieve Commodagh, wish we did. " — colleenmarie512 • Sep 7, 2019
"The first time I did Slieve Donard was in July 2018. The plan was to do the entire Mourne wall that day but we didn't quite manage that. The walk was over 30 km though with 1600 metres of ascent so we got a good bit done on that hot day." — hannahaapio • Jul 14, 2018
