Overview
The Castlebar Greenway forms a key segment of the Great Western Greenway, a 45 km network that links the historic towns of Ballina, Castlebar and Westport across County Mayo. Starting in the heart of Castlebar, the trail follows the gentle course of the Castlebar River, runs parallel to the N5, and then meanders through riverside woodlands, open fields and a stretch of Lough Lannagh before reaching the tranquil Rehins Wood near Islandeady. The surface is solid – either tarred or compacted – making it suitable for walkers, joggers and cyclists of easy to moderate fitness.
History & Background
The Greenway was conceived as part of a wider initiative to create a safe, sustainable inter‑urban corridor linking Mayo’s three largest settlements. While the broader Ballina‑Castlebar‑Westport Interurban Greenway (BCWIG) project is still under study, the Castlebar‑to‑Turlough section is already open and fully way‑marked. The route’s development reflects Ireland’s national strategy to promote active travel, boost rural tourism and provide a commuter‑friendly alternative to the busy N5 road.
What to See & Do
Scenic Highlights
- Castlebar River – The trail hugs the river for several kilometres, offering reflective water views and opportunities to spot local wildlife.
- Lough Lannagh – A short detour brings you to the lake’s edge, where you can pause on the car‑park or holiday‑village facilities and enjoy the tranquil waters.
- Rehins Wood – A pocket of native woodland near Islandeady provides a shaded, leafy contrast to the open fields.
Cultural Stops
- National Museum of Ireland – Country Life (Turlough) – Located at the Turlough trailhead, the museum showcases rural Irish life through artefacts, photographs and interactive displays.
- Castlebar Town Centre – The urban section passes through Castlebar’s historic streets, allowing a quick coffee stop or a glimpse of the town’s Georgian architecture.
Activities
- Cycling – The solid surface and gentle gradient make the route perfect for hybrid or mountain bikes. Blue‑and‑white way‑marking keeps you on track.
- Walking & Jogging – With minimal ascent, the path is ideal for leisurely walks, family outings or a steady jog.
- Dog‑Friendly Strolls – Dogs are welcome on a lead, adding to the family‑friendly appeal.
Events & Seasonal Highlights
The greenway hosts occasional community runs and charity rides, particularly in the spring and summer months. Check the official Greenway website for the latest calendar of events.
Current Status & Closures
The greenway is generally open year‑round, but sections may be closed temporarily for maintenance. The most recent closure affected the stretch between Summerfield Estate in Castlebar and the RSC Fitness & Martial Arts site (formerly N5 Tyres). It was shut from 25 June 2025 until 9 July 2025 to allow asset renewal works and essential maintenance. Visitors should check the official website before planning a trip, especially during the summer months when such works are most likely.
Future Development
Mayo County Council, in partnership with Transport Infrastructure Ireland and the Department of Transport, is advancing the Ballina‑Castlebar‑Westport Interurban Greenway (BCWIG). Once completed, the network will provide a continuous, traffic‑free corridor of up to 60 km, linking the three largest towns in the county. The project aims to boost tourism, create commuter options and stimulate local businesses such as bike‑tour operators and cafés along the route.
Practical Information
The Castlebar Greenway is open year‑round and free to use. Trailheads are conveniently located at:
| Trailhead | Facilities |

Distance breakdown
- Total network length: 45 km
- Castlebar → National Museum at Turlough: 10 km
- Castlebar → Rehins Wood (Islandeady): 6 km
- Lough Lannagh loop: 16 km
- Islandeady → Westport (on‑road section): 13 km
The route is primarily traffic‑free, but a short on‑road segment connects Islandeady to the Westport Greenway. Cyclists should be familiar with Irish road rules, wear a helmet and use lights after dark. Visibility is enhanced by bright clothing and reflective strips, and a bell is recommended to alert pedestrians on the off‑road sections.
Recommended gear includes walking shoes, a waterproof jacket, a helmet, a hybrid or mountain bike, a mobile phone, and plenty of water and snacks. While the surface is solid, checking tyre pressure before setting off ensures a smooth ride.
Accessibility – The solid, compacted surface makes the trail wheelchair‑friendly in many sections, though some on‑road stretches may present a slight challenge for users with limited mobility.
Getting there – Castlebar is well‑served by bus and rail, with regular connections from Dublin, Galway and other Irish cities. From the town centre, follow the blue‑and‑white way‑marks that guide you onto the greenway. Parking is free at the Lough Lannagh and Rehins Wood carparks, and there are ample facilities at the National Museum site.
