About this trail
Great Western Greenway — Trail Guide
The Great Western Greenway is a spectacular 42km traffic-free trail stretching from Westport to Achill Sound, following the former railway line through County Mayo's most stunning scenery. This primarily flat to gently rolling route features exceptional coastal and mountain views, particularly as you approach Achill with dramatic Croagh Patrick visible for much of the journey. The surface is a mix of tarmac and well-maintained gravel, making it ideal for all abilities. Gradients are minimal throughout, with the route gaining only modest elevation, making it perfect for long-distance riding. The trail passes through charming villages including Louisburgh and Clare Island views, with excellent signposting at regular intervals. Practical tip 1: Start early in summer months to avoid crowds and enjoy the best light for photography. Practical tip 2: Stock up on supplies in Westport before departing, as services become more limited after Louisburgh, though cafes are available in smaller villages along the way.
Ebike Suitability
The Great Western Greenway is absolutely perfect for ebikes due to its length, predominantly flat terrain, and family-friendly nature. Mid-range city or trekking ebikes with 250W motors are ideal, though cargo ebikes work well if you're carrying supplies. Battery capacity of 500-625Wh is sufficient for the full 42km, even with moderate pedal assist engaged throughout. E-assist proves invaluable for maintaining steady pace over the entire distance without fatigue, allowing riders to focus on the magnificent scenery rather than exertion. The consistent terrain means you'll enjoy smooth, predictable assistance with minimal power drain on climbs. Heavier riders or those carrying luggage benefit most from ebike motors on this route, as you can maintain higher speeds and complete the journey comfortably in a single day.
What Riders Say
Riders consistently praise the Great Western Greenway for its world-class scenery and impeccable maintenance. The dramatic backdrop of Croagh Patrick, combined with sweeping views of Clew Bay's island-studded waters, creates unforgettable riding experiences. Many highlight the excellent signposting and smooth, well-maintained surface that makes navigation effortless. Cyclists rave about the peaceful, car-free environment and the wonderful sense of progression from Westport's charming town centre to the wild beauty of Achill Head. Families particularly appreciate the gentle gradient and numerous rest points. Visitors frequently mention the magical experience of riding through changing landscapes, from pastoral farmland to coastal wilderness, and the surprise wildlife encounters including sea eagles and coastal birds. The investment in facilities like parking, cafes, and rest areas throughout the route receives consistent positive feedback.
