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.

Beautiful views of Furnace Lough here from the road appropriately called Furnace. There is a lovely bench here wrapped around a tree where you could rest. It's also worth remembering that the large Loch Feeagh is a very short walk to the north from here - like, under 5 minutes. A rather lovely little stream called Outflow connects the two loughs.

Be sure to use the Greenway instead of the N59 expressway on this section! This is a beautiful stretch through forests and meadows.

The beautiful seven arched Burrishoole Bridge was erected in the 18th century when the road between Newport and Mulranny was built to allow people to cross the Burrishoole Channel. It perfectly blends in with the romantic landscape and it is one of the most peculiar bridges in Mayo.
