Cycling the Great Western Greenway: Westport to Achill
42 km of traffic-free trail from Westport to Achill Sound, broken into four stages. Shuttles and bike hire are easy to arrange at either end.
Introduction
The Great Western Greenway runs from Westport out to Achill Island. Much of it sits on the bed of a disused railway, and railway engineers disliked gradients, which is why the trail stays gentle for almost its entire length. At 43.5 km (≈ 27 mi) it is the longest off-road greenway in the Republic, running on former railway lines, quiet country lanes and purpose-built cycle paths.
Most of it is genuinely traffic-free. The exception is Newport, where the route puts you on the main road through the town centre with no cycle lane at all. That is the section that catches people out.

2. Planning Your Ride
2.1 When to Go
- Spring (April-May): Wildflowers bloom, temperatures 10-15 °C, fewer tourists.
- Summer (June-August): Long daylight (up to 16 h), but expect higher temperatures and occasional rain showers.
- Autumn (September-October): Golden foliage, milder crowds, still plenty of daylight.
Avoid the mid-winter months when sections can become muddy, and daylight is limited.

3. Stage-by-Stage Breakdown
Stage 1: Westport to Newport (≈ 12 km)

Stage 2: Newport to Mulranny (≈ 18 km)
- Terrain: Mix of paved sections through Newport town and off-road track along the coast.
- Challenges: The Newport town centre can be busy; there is no dedicated cycle lane on the main road. Use the pedestrian crossing at the Seven-Arches Bridge and stay on the right side.

4. Practical Tips for a Smooth Experience
| Tip | Why it matters |
|---|---|
| Check the weather before you set off, use Met Éireann or a reliable app. | Irish weather can shift from sunshine to rain in minutes. |
| Carry cash as some small cafés may not accept cards. | Rural towns often rely on cash for small transactions. |
| Mind the tide at coastal sections near Mulranny, the path can be damp after high tide. | Wet surfaces become slippery, especially on sand-packed sections. |
| Use the official greenway signs (blue-green circles) and avoid shortcuts on busy roads. | Signage is generally good, but a few sections (Newport) require extra vigilance. |
| Leave no trace, pack out any litter and respect private farmland. | The trail passes through grazing land; preserving it keeps the greenway open. |
| Plan breaks, each town offers a rest stop with toilets and refreshments. | Regular stops help maintain energy levels and avoid dehydration. |
| Bike storage, lock your bike at designated racks if you plan to explore a town on foot. | Secure racks are available in Westport, Newport, Mulranny and Achill. |
5. Where to Stay: Accommodation Options
| Town | Recommended stay | Type | Approx. price per night |
|---|---|---|---|
| Westport | The Mariner (central, good value) | Guesthouse/Hotel | €90-€120 |
| Newport | Walsh’s Bridge Inn (family-run, cosy) | B&B | €80-€110 |
| Mulranny | Nevins Newfield Inn (village centre) | B&B | €85-€115 |
| Achill | Greenway Lodge B&B (steps from trailhead) | B&B | €70-€95 |
| Achill (luxury) | Keel House Hotel (sea-view) | Hotel | €130-€170 |
Most establishments provide bike rack space and can arrange bike hire return if needed.
6. Nearby Attractions Worth Adding to Your Itinerary
- Croagh Patrick: Ireland’s holy mountain; a short drive from Westport for a hike.

Combining the greenway with any of these sights turns a single-day ride into a mini-vacation.
7. Frequently Asked Questions
Q: Can I ride the Greenway in one direction and have the bike collected at the other end?
A: Yes. Most hire shops (Paddy & Nelly, Clew Bay Bike, Achill Bike Hire) offer a drop-off service for a small fee (≈ €5-€10). Arrange it when you pick up the bike.
Q: Is the trail suitable for road-only bikes?
A: While a road bike will manage most of the route, the gravel sections and occasional sand-packed track can be uncomfortable and increase puncture risk. A hybrid or gravel bike with wider tyres is recommended.
Q: Are dogs allowed on the Greenway?
A: Yes, dogs are permitted but must be on a lead where the path passes near livestock or busy roads.
Q: What are the opening hours?
A: The Greenway is open 24 hours year-round. However, some facilities (toilets, water points) close at night, so plan to finish before dusk.
Q: Is there mobile coverage along the route?
A: Coverage is generally good in towns, but can be spotty on the open coastal sections. It’s wise to download offline maps and inform someone of your itinerary.
Conclusion
Half a day of riding, four towns with cafés and toilets along the way, and one short stretch of real road at Newport. That is the whole of it. It works as a day out from Westport, as a family ride split over two days, or as one leg of a longer trip west.
Arrange the bike drop-off when you collect the bike rather than afterwards. Check Met Éireann the night before. And carry some cash, because not every café out there takes a card.
