Overview

The Great Western Greenway is Ireland’s original and best-known rail-trail, a 42km route that follows the former Midland Great Western Railway from Westport to Achill Sound. Opened in phases from 2010 and completed in 2011, it became the blueprint for greenway development across Ireland. The Greenway traverses a breathtaking Atlantic landscape, running parallel to Clew Bay and framed by the Nephin Beg Mountains and Croagh Patrick. It links the towns of Westport, Newport, Mulranny and Achill, each offering services, accommodation and cultural attractions.

The route is traffic-free, well surfaced and designed for walkers and cyclists of all levels. Highlights include sweeping sea views, stone viaducts, old station houses and boardwalk-like causeways across saltmarsh fringes. The Great Western Greenway has won multiple awards and has drawn international acclaim, bringing significant tourism and economic benefits to the region. Whether you ride the full distance or enjoy a short family outing, the Greenway provides an unforgettable encounter with Mayo’s dramatic coastline, its heritage towns and its living landscapes. It is a flagship for sustainable tourism and a shining example of how disused railways can be reimagined as world-class visitor experiences.

Westport – Newport

Biodiversity

The Great Western Greenway passes through and overlooks the Clew Bay Complex Special Area of Conservation (SAC) and Special Protection Area (SPA). This designation reflects the ecological importance of its saltmarshes, lagoons, reefs and tidal flats. These habitats support migratory and wintering bird species, including curlew, redshank, oystercatcher and brent goose. The saltmarsh fringes are rich in plant life, including glasswort, thrift and sea aster, which flower in summer and attract pollinators.

The wetlands support invertebrates that in turn sustain wader populations. Inland, the hedgerows and moorland provide habitats for stonechat, meadow pipit and kestrel. The waterways near Newport also support otters, salmon and lamprey. Amphibians like the common frog breed in small ponds and drains, while dragonflies and damselflies are abundant in summer. The diverse landscape makes the Greenway both a corridor for human recreation and a living ecological system. Visitors are asked to remain on the surfaced path, particularly in saltmarsh areas, and to avoid disturbing birdlife. This ensures that the Greenway continues to provide a safe refuge for wildlife while also allowing people to enjoy the extraordinary biodiversity of Mayo’s coast.
