Mourne Mountains: Slieve Commedagh from Newcastle

County Down

Dog Friendly Rating:7/10A dog friendly big day in the Mournes climbing Slieve Commedagh from Newcastle via the Glen River.

Slieve Commedagh is the second highest peak in the Mournes at 765 metres, often climbed as a partner to Donard but a fine target in its own right. The dog friendly route from Donard Park rises through the Glen River forest before breaking onto the open fell and the Mourne Wall for the summit push.

Dogs must be on a lead at the base where sheep use the river corridor and again at the final summit approach where the exposed ground is dangerous for loose dogs. Expect a mix of stone stepped path, rough grass and granite boulders, with a total ascent around 760 metres. Parking is pay and display at Donard Park with toilets, cafes and shops a short walk along Newcastle promenade.

Frequently Asked Questions

  • Is Mourne Mountains: Slieve Commedagh from Newcastle dog friendly?

    Slieve Commedagh from Newcastle is a solid choice for dogs, earning a rating of 7.5 out of 10 on Wildpack Collective. The route via Donard Park and the Glen River offers a genuinely rewarding big day out in the Mournes, though there are a couple of sections where leads are required, so it suits dogs that are comfortable on varied mountain terrain.

  • Can dogs be off lead at Mourne Mountains: Slieve Commedagh from Newcastle?

    There are sections where leads are essential rather than optional. Dogs must be kept on a lead near the base where sheep graze along the river corridor, and again on the final approach to the summit where the exposed ground poses a real risk to loose dogs. In between, the open fell offers more freedom, but always use your judgement on a mountain route like this.

At 765 metres, Slieve Commedagh is a big day out, so plan ahead and check conditions before you set off.
