This route was planned by komoot.
This specific komoot touring bicycle route, despite its name, is indeed located in the Mourne Mountains, starting from Newcastle, County Down, Northern Ireland. Slievenamon Mountain is actually in County Tipperary, Republic of Ireland. This route offers a challenging ride through the Mournes, not around Slievenamon.
This route is quite substantial, covering approximately 55.3 kilometers (34.4 miles). On average, cyclists can expect to spend around 3 hours and 43 minutes in the saddle to complete it, depending on their pace and stops.
The route starts from Newcastle in the Mourne Mountains. While specific parking details aren't provided, Newcastle is a well-known tourist town with various public parking options available. It's advisable to check local parking facilities in Newcastle before your visit.
Expect a demanding and rewarding experience. The terrain is generally hilly, featuring coastal roads, significant climbs, and long descents. You'll encounter strenuous sections, including iconic climbs, and some moorland areas can be quite windy. Good fitness is essential for this route.
You'll be treated to spectacular coastal and mountain views throughout. Highlights include a View of Castlewellan Castle, the challenging Slievenaman Climb, and a stunning View of the Mourne Coast at Bloody Bridge. The route also passes through picturesque areas like Tollymore Forest Park and offers vistas of Dundrum Bay and Slieve Donard.
Given its 'difficult' rating, significant elevation gain of over 700 meters, and hilly terrain, this route is not recommended for beginners. It requires good fitness and experience with sustained climbs and steep sections. Novice cyclists might find parts of it too strenuous.
Yes, this touring cycle route incorporates sections of several other official trails. Notably, it uses parts of Route 1 - The Newcastle / Lough Island Reavy Route, the Newcastle Way, and Route 6 - The Head Road Route.
The Mourne Mountains offer stunning scenery, but weather can be unpredictable. Spring and autumn often provide pleasant temperatures and fewer crowds. However, be prepared for potentially windy conditions, especially in moorland sections. Always check the local forecast before you go.
Generally, there are no specific permits or entrance fees required to cycle this public route through the Mourne Mountains. As part of the Mourne Gullion Strangford UNESCO Global Geopark, the area is managed for conservation and public enjoyment. However, always respect local signage and regulations, especially if passing through private land or specific attractions like Tollymore Forest Park, which may have their own entry fees or parking charges. You can find more information on local regulations at visitmournegullionstrangford.com.
This route is designed for touring bicycles, and while dogs are generally welcome in many outdoor areas of the Mournes, bringing a dog on a bicycle can be challenging, especially on a difficult route with significant climbs and descents. If you plan to bring a dog, ensure they are safely secured in a bike trailer or basket and that you adhere to all local leash laws and clean-up regulations, particularly when passing through populated areas or nature reserves.
Starting and ending in Newcastle, you'll find a good selection of cafes, pubs, and restaurants to refuel before or after your ride. Along the route, particularly through villages like Castlewellan, you may also find options for refreshments, but it's always wise to carry enough water and snacks, especially on longer, more remote sections.
