Cycling Ireland in Spring: Routes for March to May

Introduction

March to May gives you 12 to 16 hours of daylight, temperatures between 8 and 15 °C, and far fewer people on the popular routes than you will meet in July. It also gives you showers. The rivers run high with the last of the winter rain, the hedgerows come in quickly, and accommodation is still on off-peak rates.

Cycling Ireland reports that recreational participation rose by over 35 % between 2020 and 2024, with more than 400 000 people cycling weekly. Greenway building has kept pace with it, which is mostly why the traffic-free mileage below exists at all.

Why Spring Is the Ideal Time to Cycle Ireland

Factor	Spring (March-May)	Summer (June-August)
Daylight	12–16 h, sunrise ~7 am, sunset ~8 pm	16–18 h, very long days
Weather	Mild (8-15 °C), occasional showers, less heat	Warm (15-22 °C), occasional heatwaves
Crowds	Fewer tourists on popular routes	Peak tourist season, busier roads
Scenery	Wildflowers, fresh green, blooming hedgerows	Full-summer foliage, but less colour contrast
Prices	Off-peak accommodation and bike rentals	Higher rates, especially in coastal towns

The practical upshot is that you can ride longer without cooking. Hawthorn is out by May. The roads are quiet enough that you can stop where you like rather than where there is a lay-by.

Top Spring Cycling Routes

1. Great Western Greenway: Mayo (42 km)

• Start/Finish: Westport → Achill Island (via Newport & Mulranny)
• Surface: Compact crushed stone, fully traffic-free
• Spring Highlights:
  • Clew Bay sparkles with early-season sunlight.
  • Wildflowers such as bluebells and primroses line the towpath.
  • Croagh Patrick is often shrouded in mist, adding a mystical backdrop.

Tips: Rent a hybrid or e-bike in Westport and take a short break at Mulranny to sample local seafood. It is flat and it is crushed stone the whole way, so narrow road tyres are the wrong tool here.

2. Waterford Greenway: Waterford to Dungarvan (46 km)

• Surface: Smooth tarmac, perfect for road bikes and families.
• Key Features: Durrow railway tunnel, Kilmacthomas viaduct, scenic riverside sections.
• Spring Highlights:
  • Apple blossoms along the River Suir create a fragrant ride.
  • The Waterford Greenway generated €14 million in tourism revenue in 2023, proving its popularity and quality of facilities.

Tips: Pack a picnic for the Dungarvan Harbour. Bike-repair stations are located at both ends and at Kilmeaden.

3. Ring of Kerry: County Kerry (175 km)

• Surface: Mix of paved roads and narrow rural lanes.
• Difficulty: Challenging; best tackled over 2-3 days.
• Spring Highlights:
  • Moll’s Gap and Ladies View burst with heather and early-season lupins.
  • Fewer tourist buses mean quieter climbs and clearer vistas of the Iveragh Peninsula.

Tips: Start early (around 6 am) to avoid the occasional bus convoy. Break the loop at Waterville or Cahersiveen rather than attempting the full 175 km in a day.

4. Royal Canal Greenway: Maynooth to Cloondara (130 km)

• Surface: Flat, well-maintained towpath suitable for all abilities.
• Spring Highlights:
  • Willow and ash trees along the canal turn a fresh green, perfect for photography.
  • Rural villages such as Enfield and Mullingar showcase traditional pubs with spring-time live music.

Tips: Break the journey into two sections: Maynooth-Enfield (≈45 km) and Enfield-Cloondara (≈85 km). Local cafés provide hearty Irish breakfasts to refuel.

5. Bear a Peninsula Loop: Cork/Kerry (138 km)

• Surface: Predominantly paved, some narrow, winding sections.
• Spring Highlights:
  • Healy Pass offers dramatic early-season cloud formations over the Atlantic.
  • Dursey Island cable car (bike-free) provides a unique side-trip for a short rest.

Tips: The loop is best ridden in late May when the weather is stable but the crowds are still thin. Carry a waterproof jacket, Irish spring showers are common but brief.

Quieter Trails Worth Knowing About

Trail	Location	Length	Best For
Old Rail Trail Greenway	Athlone → Mullingar	30 km	Easy family rides
Phoenix Park Loop	Dublin	7 km	Urban cycling, wildlife spotting (deer)
Limerick Greenway	Rathkeale → Abbeyfeale	40 km	Castles, viaducts, short day rides
Clifden Sky Road	Connemara	25 km (loop)	Coastal climbs, sunsets
Ballyhoura MTB Trails	Limerick/Cork border	20 km of purpose-built tracks	Mountain biking, adrenaline seekers

None of these get the coach traffic. Ballyhoura is the odd one out: purpose-built mountain-bike tracks rather than a greenway, so check what you are bringing before you drive there.

Practical Spring Cycling Tips

1. Dress for Changeable Weather

   • Layer a breathable base, a wind-proof jacket, and waterproof shell.
   • Pack a compact poncho or light raincoat, rain showers can appear suddenly, even in May.

2. Bike Rental & E-Bike Options

   • Major towns (Westport, Waterford, Killarney, Dublin) have e-bike fleets.
   • Booking ahead secures the best models and often includes a helmet and lock.

3. Navigation

   • Download offline maps via Komoot, RideWithGPS, or Strava.
   • Many greenways have signposted route markers (green leaf symbols).

4. Safety

   • Wear high-visibility clothing, especially on shared roads.
   • Helmets are not legally required in Ireland but are strongly recommended.
   • Carry a basic repair kit (spare tube, tire levers, pump).

5. Charging & Amenities

   • Greenways such as the Waterford and Great Western now feature e-bike charging stations at major stops.
   • Rest points often have cafés, toilets, and bike-repair stands.

6. Public Transport

   • Iarnród Éireann (Irish Rail) allows bikes on most services (reserve space for larger bikes).
   • Dublin’s Luas and DART permit bikes outside peak commuter hours (7-9 am & 4-6 pm).
   • Bus Éireann accepts foldable bikes on most routes.

FAQs About Cycling in Ireland

Is Ireland safe for cyclists?
Yes. Dedicated greenways are completely traffic-free. Rural roads are generally low-traffic, but always wear a high-visibility vest and use a front light after dusk.

When is the best time to cycle in Ireland?
Late April to early June offers the longest daylight, mild temperatures, and blooming scenery without the summer crowds.

Can I bring my bike on public transport?

• Trains: Allowed on all services (reserve space for larger bikes).
• Luasa/DART: Allowed outside peak hours.
• Bus Éireann: Foldable bikes only; larger bikes need a reservation on specific services.

Are e-bike rentals widely available?
Yes. Greenways such as the Great Western, Waterford, and Royal Canal have e-bike hire points, often with charging stations at the start and end of the route.

Do I need a helmet?
While helmets are not mandatory under Irish law, they are strongly advised for safety and are required by most rental companies.

Conclusion

Spring buys you the greenways before the summer crowds arrive and at off-peak rates. It costs you the weather. That is the trade, and most riders take it.

Start on a greenway if you have not toured before. The Waterford and Great Western surfaces are easy and there is no traffic to think about. Leave the harder loops of Kerry or Bear a until you know what you can comfortably cover in a day.

Take a waterproof jacket you actually trust, and book the bike hire ahead of the weekend.
