42 kilometers of smooth cycling through County Mayo. Detailed section-by-section breakdown, best stopping points, and what to expect on the full route.
The Complete 42km Journey
The Great Western Greenway isn't just another cycling route — it's a beautifully restored railway line that's been transformed into one of Ireland's most accessible cycling paths. We've cycled it dozens of times and want to share exactly what you'll encounter along the way.
This guide breaks down each section, tells you where the best stops are, and gives you realistic expectations about what you're cycling into. Whether you're planning a leisurely day ride or tackling the full 42 kilometers, you'll find the information you need here.

Starting from Westport: The First 12km
You'll start in Westport town center, and the greenway entrance is clearly marked near the main street. The path is paved and smooth from the very beginning — no gravel sections to worry about.
The opening stretch runs alongside the Carrowbeg River. You're cycling gently downhill (honestly, barely noticeable) as the landscape opens up. Around the 5km mark, you'll pass through some tree cover that provides nice shade on sunny days. By 8km, you've entered agricultural land with open views across fields toward Croagh Patrick mountain.
There's a proper rest area at Magheroe (around 10km) with benches and bins. It's a good spot to pause, stretch your legs, and hydrate. Most cyclists stop here for 10-15 minutes before continuing.
The Middle Section: Mulranny to Achill Road
Between kilometers 12 and 28, you're cycling through genuinely beautiful terrain. The path widens in places and you'll notice the original railway embankments on either side — it's a nice reminder you're following a historic route.
Mulranny village (around 18km) is worth stopping for. There's a café right by the greenway, proper toilets, and it's the kind of place where you can grab a sandwich or coffee without rushing. We usually spend 20-30 minutes here on longer rides.
The section from Mulranny onward gets quieter and more scenic. You're cycling past small farms, woodland patches, and occasionally you'll spot locals on the path too. Between 22-25km, there's a particularly nice stretch with mature trees providing shade. It's cooler here and feels like you've entered a different landscape entirely.
Planning Your Route
This guide is based on current conditions as of June 2026. Weather, seasonal changes, and maintenance work can affect cycling conditions. Always check local weather forecasts before heading out, wear appropriate safety gear including a helmet, and bring water and snacks. If you're new to cycling or have health concerns, it's worth discussing your plans with your GP first.
Final Push: Achill Road to Newport
The last 14 kilometers take you through more open countryside. This section tends to be windier — you're more exposed to Atlantic winds — but the views are worth it. On clear days, you can see across to Clare Island.
Around 35km, there's another proper rest area with facilities. Don't skip this one if you need it. The final 7km into Newport are straightforward cycling, and you'll know you're approaching town when you see the industrial estates on either side of the path.
Newport endpoint has good facilities — parking, a café, and clean toilets. If you've cycled the full 42km, you'll absolutely deserve a proper break here. Most cyclists spend at least 30-45 minutes in Newport before heading back or arranging transport.
What to Know Before You Go
Here's what we've learned from countless rides on this route:
Bike Type Matters
Any bike works here — hybrid, road, or mountain. The surface is tarmac throughout, so you don't need off-road tires. Wider tires (around 45mm) feel more comfortable than thin road bike tires on longer rides.
Bring Water
Don't rely on finding water en route. Bring at least 1.5 liters if you're doing the full ride. The rest areas have benches but not all have water fountains. Westport and Mulranny have shops, but don't assume everywhere does.
Weather Can Change
You're cycling exposed terrain for much of the route. Wind can pick up in the afternoon. We'd recommend starting early (before 10am) to avoid afternoon Atlantic winds and to have plenty of daylight for the ride back or journey home.
Distance Flexibility
You don't have to do the full 42km. Westport to Mulranny is 18km (90 minutes) and absolutely doable as a half-day ride. Many cyclists do this section and call it a day — it's genuinely satisfying without being exhausting.
Mobile Signal
Signal is spotty on the greenway itself, especially in rural sections between Mulranny and Achill Road. Download offline maps on your phone before starting. You won't need GPS constantly, but it's helpful for navigation at rest stops.
Safety Basics
Wear a helmet — it's not optional. The greenway is shared with pedestrians and other cyclists, so keep to the right and call out when passing. Lights aren't essential in daylight but we'd recommend rear lights if you're riding into evening.

Plan Your Great Western Greenway Adventure
The Great Western Greenway isn't just a cycling route — it's a chance to experience some of Ireland's most beautiful countryside at your own pace. Whether you're doing the full 42km or breaking it into smaller sections, you'll understand why this route has become so popular with cyclists of all ages and abilities.
Start early, bring water, and don't rush. The best part of cycling a greenway is the journey itself — the landscape gradually changing, the rhythm of your pedaling, and the satisfaction of knowing you're moving through the world under your own power. That's what makes the Great Western Greenway special.
