Is Key

Dress for the Mountain, Not the Car Park

The Mourne Mountains create their own weather. It can be sunny at the trailhead and sleeting on the summit an hour later. The right gear is the difference between a magical day and a miserable one. Whatever the season, waterproofs and layers are non-negotiable.

The Golden Rules

No matter when you visit, these principles apply every single day in the mountains.

“If you're heading into the mountains, pack for winter even in summer. Summits are 10°C colder than valleys.”

Cotton kills. Wear moisture-wicking fabrics, not cotton t-shirts that hold water.

Break in your boots before you come. New boots + mountain = blisters.

Irish weather is unpredictable. Layers you can add and remove beat one big coat.

Leave an itinerary with someone. Tell them where you’re going and when you’ll be back.

You've got the gear sorted. Now plan your route to the Mournes and find a trail that suits you.
