Great Western Greenway
Overview
Mayo’s Great Western Greenway is a 49-kilometre route stretching from Westport to Cashel on Achill Island, taking in Newport and Mulranny along the way. You couldn’t ask for a more picturesque setting, as you drift from the bustling town of Westport along to the pretty village of Newport before you move on along the coast to Mulranny and finally out to the gorgeous island of Achill.
Offering mild gradients courtesy of its initial beginning as a railway line and with magnificent landscape backdrops such as Clew Bay, Clare Island, the mythical holy mountain Croagh Patrick and the Nephin Beg Mountains which forms Part of Wild Nephin National Park, this route can be used by walkers and cyclists of all levels. This was Ireland’s first greenway with the first section opening in 2011. Since then, this route has won multiple awards and has drawn international acclaim, bringing significant tourism and economic benefits to the region.
Westport – Newport
Starting in the vibrant town of Westport, an official access point is located to the right just off the N59 travelling in the direction of Westport. You can also start from the centre of the town with greenway signage directing you via quiet residential streets to the route or alternatively from the east side of the town with the greenway looping to the west side.
As you leave Westport behind, you will travel adjacent to the N59 with a verge and a barrier providing separation from passing vehicles. You will encounter the first of the distinctive red gates which are a feature of the entire greenway – these are copies of the original gates used on the railway line.
The route merges with the main road into Newport. Cyclists can opt to dismount to travel through the village or may feel comfortable travelling on the hard shoulder for a short distance. This is a scenic village with features includes the distinctive Newport Viaduct (a reminder of the railway heritage of this greenway route) and a 19th-century church with Harry Clarke-stained glass. There is plenty of seating at the picturesque harbour with cafes in the village.

Clew Bay is a designated special area of conservation with a wide variety of marine and terrestrial habitats including tidal mudflats and sandflats, saltmarshes, marram dunes and old oak woodlands. The bay is home to a wide range of species including otters, common seals and a diversity of wintering waterfowl. The diverse range of ground flora include red fescue, ribwort plantain, field gentian, yellow iris, bog orchid, water mint as well as bluebell and wood-sorrel with woodlands populated by downy birch, hazel, hawthorn and the occasion sessile oak. Much of the greenway route passes through environmentally sensitive areas.
The Great Western Greenway exemplifies sustainable infrastructure by repurposing a disused railway corridor with minimal environmental disruption. The route includes Ireland’s widest boardwalk, constructed over undisturbed bogland, preserving sensitive habitats and supporting biodiversity. Environmental sustainability is embedded in its design and management with initiatives including tree, hedgerow, and wildflower planting to enhance biodiversity and create wildlife corridors. Community involvement is central to its success. Local schools and volunteers participate in biodiversity surveys and habitat monitoring, fostering environmental awareness and stewardship.
Environmental innovation is central to the initiative, with features such as solar-powered compactor bins, refill water stations, e-bike charging stations, and public furniture crafted from repurposed wind turbine blades—demonstrating circular economy principles in action. The Greenway also promotes responsible outdoor recreation through the Leave No Trace principles. Visitors can experience this rich biodiversity from the route itself. Respecting signage and keeping to the trail are essential, especially in environmentally sensitive places.
