For a hike in Mourne Mountains, bring proper safety and navigation equipment even on short walks (unexpected mist can lower visibility), and don’t rely on mobile phone signals to work all over the mountains. Bring a rainproof jacket, warm layers, and proper hiking boots, plus water and food. There are no shops in the mountains, and streams and rivers may not be reliable for drinking water. The landscape can be boggy in places, and paths can become waterlogged during heavy rainfall. Check walking trails and terrain considerations at local tourist information centres.
