    Route Description for Slieve Donard Trail

    The Slieve Donard Trail is a beautiful, and at times challenging, adventure that will lead you up to the summit of Northern Ireland’s highest peak. This inevitably makes it a popular route for a wide range of walkers, so be sure to arrive early. Even though there is a stone footpath leading up to the summit, you will need to wear proper walking boots with good support and make sure that your level of physical fitness is up to par.

    Although it may be steep in certain areas, this is an exceptional walking route that you will need to try if you find yourself in the Mourne Mountains. Stunning panoramic views overlooking the rugged terrain of Northern Ireland and the blue expanse of the Irish Sea await on this breathtaking adventure to the highest point in the country.

    Setting out from the car park, you will make your way to the southwest and follow along the banks of the Glen River for 0.4 km, turning left to cross over the water. Shortly after passing over the river, you will pick up a footpath on the right that will continue to lead you in a southwestern direction. After walking through the serene forest of another 0.4 km, you will turn right and once again cross the river, before turning left at the first junction.

    Continuing on to the southwest, you will follow along the banks of the Glen River as they eventually break free from the tree cover and begin to climb up the mountainside towards Slieve Donard. Using the river and stone pathway as your guides, you will follow this riverside path for the next 1.87mi, working your way uphill into the rugged expanse of the Mourne Mountains.

    After arriving at a junction, you will turn to the left and make the steep final ascent of Slieve Donard, where you will enjoy stunning views of the surrounding landscape and Irish Sea from the summit of the mountain. After taking in the views, carefully make your way down the mountainside along the same route to eventually return to the car park where you began your adventure along the SLieve Donard Trail.
