The best running trails in Mayo

Between Newport and Mulranny, the Greenway follows the old railway line through a varied landscape of reed fields, tidal water, peat bogs, and low hills. The path is wide, quiet, and gently sloping, with regular beautiful views of Clew Bay and the islands. Old bridges, stone walls, and quiet river arms give this part of the route a distinctly rural and almost timeless atmosphere.

Lough Fadda (The Long Lake): Situated directly on the south side of the Great Western Greenway, this narrow lake forms a distinctive natural border on the stage between Newport and Mulranny. "Lough Fadda" (Irish for Loch Fada) stretches for almost a kilometer parallel to the cycle path and is a typical example of a peat lake, characterized by its deep, dark water and surrounding marsh vegetation. From this point, you have a spectacular contrasting view: on one side, the serene shores of the lake, and on the other, the rugged, open vistas across the inlets of Clew Bay.

This characteristic stone bridge forms a crucial junction on the 18 km stage between Newport and Mulranny. The bridge spans the Burrishoole River at the point where the fresh water from Lough Feeagh mixes with the salty tidal waters of Clew Bay. From the Greenway, you have an unobstructed panoramic view here of the nearby 15th-century abbey ruins and the fish traps that have been used for centuries to catch wild salmon and eel, against the backdrop of the rugged Nephin Beg Mountains.

(Heritage Town & Greenway Hub) This picturesque town, also known as Ballyveaghan, forms the geographical heart of the Great Western Greenway and is the ancestral home of Princess Grace of Monaco. Newport (approx. 600 inhabitants) is located on the northeastern corner of Clew Bay, where the Black Oak River meets the sea, and is known for its rich maritime history and fishing. For cyclists on the Wild Atlantic Way, it is a crucial stop with essential amenities such as supermarkets (e.g. Centra), cozy pubs, and a unique atmosphere where the rugged Nephin Beg Mountains and the 365 islands of the bay converge.

Seven Arches Viaduct (Historic Landmark): This impressive 1892 red sandstone railway bridge spans the Black Oak River in the heart of Newport and is one of the most photographed points on the Great Western Greenway. The viaduct consists of seven arches with a total length of approximately 70 metres and served as a crucial part of the railway link between Westport and Achill Island until 1937. From the top, you have panoramic views over the tidal river and the nearby St. Patrick's Church, which is renowned for its rare stained-glass windows by Harry Clarke. (note: this is the 2nd bridge, railway)

From the central bridge over the Carrowbeg River, experience the unique elegance of Westport. Looking along the tree-lined avenues of The Mall, you'll see how the 18th-century architecture and the babbling waterfalls merge into a harmonious whole. With colourful facades reflecting in the water and stately stone walls on either side, this is the perfect spot to park your bike for a moment and capture the "Venice of the West" on film.

Mother nature at her best.

Beautiful trail run. Currently (Aug 2025) the path along the lake is not possible due to felled trees.
