A Guide To Each Stage Of The Great Western Greenway Cycle (AKA The Mayo Greenway)

A Guide To Each Stage Of The Great Western Greenway Cycle (AKA The Mayo Greenway)

The Great Western Greenway (aka the Mayo Greenway and the Westport Greenway) is one of the best things to do in Mayo if you like to get active.

The Mayo Greenway (Westport to Achill) is officially Ireland’s longest greenway, stretching for an impressive 40km along Ireland’s stunning west coast. 

In the guide below, you’ll discover everything you need to know about tackling the Great Western Greenway, from each stage of the cycle to what to see on the way.

Some quick need-to-knows about the Great Western Greenway

As is the case with the Blessington Greenway and the brilliant Waterford Greenway, the Mayo Greenway is nicely laid-out and reasonably straightforward.

However, there are a handful of need-to-knows that’ll make your visit that bit more enjoyable.

1. Where it starts and ends

The Mayo greenway begins in Westport Town (hence why some call it the Westport Greenway) and ends on Achill Island. It uses the old rail route crossing the stunning countryside of the west coast.

2. How long it takes to cycle

The full length of the Westport greenway is 43.5km long. Depending on your speed, it takes around 5 hours to cycle one way.

3. Bike hire

If you need to hire a bike you don’t have to worry, there’s plenty of bike hire spots. Clew Bay Bike Hire has bases in each town along the route so you can hire in one place and drop it off at another town. There’s also Westport Bike Hire or Paddy and Nelly to check out as well.

While the Great Western Greenway is usually described as running from Westport to Achill, you can really start and finish at either end of the trail depending on where you’re based or arriving from.

There are obviously no hard and fast rules about completing the Mayo Greenway, so you can do it in stages as well with a few entry points along the way. 

Stage 1: Westport to Newport

From Westport to Newport, it follows mostly an off-road trail taking in some incredible Atlantic coast scenery.

The official access point and end of this section in Newport is to the left of the N59 around 2km from the town centre.

  • Distance: 12.5km
  • Cycle time (estimate): 1-1.5 hours
  • Walking time (estimate): 3-3.5 hours
  • Difficulty: Easy

Starting at the end of stage one just off the N59 outside of Newport, this section continues onto Mulranny.

The trail offers impressive views over Clew Bay and the rugged Nephin Beg mountain range in the distance.

One of the highlights of this 18km section is the Mulranny causeway which crosses Trawoughter Bay and links the village to Mulranny’s blue flag beach (arguably one of the best beaches in mayo).

  • Distance: 18km
  • Cycle time (estimate): 2-2.5 hours
  • Walking time (estimate): 5-5.5 hours
  • Difficulty: Moderate

Stage 3: Mulranny to Achill


There are two access points in Mulranny, either just off the N59 travelling to Bangor or to the rear of the Mulranny Park Hotel (one of the best hotels in Mayo).

As you head towards Achill Island, you can enjoy some truly spectacular views of the dramatic coastline with soaring cliffs and island views.

The greenway concludes in Achill Sound, the first village you come to on the island and is a great spot for a rewarding coffee or pint. 

  • Distance: 13km
  • Cycle time (estimate): 1-1.5 hours
  • Walking time (estimate): 4-4.5 hours

Right on the shores of Clew Bay, Newport is a small, picturesque town. It has the Black Oak River flowing through the centre and is a much quieter and more relaxed alternative to Westport. 

It’s a great choice for a coastal retreat, being in a nice spot along the greenway route. It’s much more limited though when it comes to accommodation choices with mostly B&Bs available.

Can you bike the Greenway one way to a certain point and then stop? We would like to start in Westport and go until Mulranny, but do not want to bike the return to Westport. Will bike rental places come get you and the bikes for a return to Westport? Thank you.
