This route was planned by komoot.
The estimated duration for this mountain bike loop is around 3 hours and 51 minutes for an average rider. However, given its length of nearly 54 kilometers and over 720 meters of elevation gain, experienced riders should plan for up to 5 hours, especially if taking breaks to enjoy the scenery or navigate technical sections.
No, this route is classified as moderate and requires good fitness and advanced riding skills. Komoot's difficulty rating corresponds to STS S2, indicating that it's best suited for experienced mountain bikers due to varied terrain and significant elevation changes.
You'll encounter a diverse range of terrain as you follow the Shannon River. The route features a mix of lough shores, challenging climbs through hills and forests, rolling hills, lough-side paths, and forest tracks. Expect quiet country roads, valley landscapes, and riverside paths, traversing rugged uplands, lakes, and gently rolling drumlins.
The route offers extensive views, following the iconic Shannon River, Ireland's longest river, which originates nearby at the Shannon Pot. You'll also enjoy breathtaking views of Lough MacNean and Cuilcagh Mountain. The area is rich in natural heritage, located within the Marble Arch Caves Global Geopark, and passes by the Ballaghnabehy Bog and Sandstone Trail.
Yes, the route incorporates sections of several other trails. You'll find yourself on parts of the North West Trail, the Kingfisher Cycle Trail - Southern Loop (Ride 2), the Leitrim Way, the Cavan Way, and the Miners Way & Historical Trail, among others.
While specific parking areas aren't detailed, Blacklion village serves as the starting point for this loop. Look for public parking options within Blacklion, County Cavan, which is the most convenient access point for the route.
Generally, trails in this region, especially those on public roads or forest tracks, are dog-friendly. However, as parts of the route may pass through farmland or sensitive natural areas, it's always best to keep dogs on a leash and ensure you clean up after them. Check local signage for any specific restrictions.
The best time to ride is typically during the spring, summer, and early autumn months (April to October) when the weather is milder and daylight hours are longer. This allows for more comfortable riding conditions and better visibility of the scenic landscapes. Be prepared for changeable weather, as is common in Ireland.
There are no specific permits or entrance fees required to ride the Ballaghnabehy and Shannon River loop itself, as it primarily uses public roads and established trails. However, if you plan to visit specific attractions within the wider Cuilcagh Lakelands Global Geopark, such as the Marble Arch Caves or the Cuilcagh Boardwalk Trail, separate fees or booking might apply for those specific sites.
This loop is a top favourite among local mountain bikers, known for its rewarding challenge. Given its length and elevation, ensure you carry sufficient water and snacks. The proximity to the Shannon Pot, the source of Ireland's longest river, is a unique geographical feature worth noting. Consider starting early to make the most of the daylight and avoid peak times, especially on weekends.
The diverse landscapes of the Cuilcagh Lakelands Global Geopark, including riverbanks, bogs, and forests, support a variety of wildlife. You might spot various bird species, including waterfowl near Lough MacNean and the Shannon River. Keep an eye out for small mammals, and enjoy the rich flora of the area, particularly in the Ballaghnabehy Bog and Sandstone Trail sections.
