Cycle 42 km of the Great Western Greenway from Westport to Achill: a mostly flat, traffic-free route that traces the old railway and serves sweeping views of Clew Bay, Croagh Patrick and the Wild Atlantic Way. Ideal for riders with basic bike-handling skills who want a full-day coastal adventure.
More ways to explore the area's outdoor wonders
A damp dawn lifts off Clew Bay as cyclists push pedals out of Westport, tyres whispering on the traffic-free surface that follows the old Westport–Achill railway. Islands in the bay sit like stepped stones, and Croagh Patrick keeps a watchful, conical profile to the south as the path threads low farmland, salt-stiff air and short, breezy climbs.
