Top Tips for cycling the Western Greenway

  • Be realistic: If 42km seems a little too ambitious, then you can opt to take on a more manageable section of the route. Covering the section from Mulranny to Achill (or vice versa) is particularly lovely.
  • Packing: Some essentials to pack are a helmet (if you are bringing your own bike), water, snacks, fully charged phone, a light backpack, rain jacket, layers, sunscreen, sunglasses and padded shorts if you are doing the full route.
  • Be safe: Adhere to the rules of the road even though you are off road; cycle on the left, pass on the right and use your bell.
  • Beware: At Newport town users of the Greenway share the street with live traffic for a distance of 1.5km.


You have your pick of great accommodation along the Western Greenway. For hotels, we recommend the Mulranny Park Hotel or Newport House Hotel, but there are plenty more options available here. If you want to camp, there is also a ton of options. In Westport, there’s Westport House and Adventure Park. As for Achill, there’s Keel Sandybanks Caravan & Camping Park. There’s also several airbnb options in both Westport and Achill as well as hostels, our favourite being the Pure Magic Lodge.
