The best time to walk the Wicklow Way is May to mid-June or September: 14–17 hours of daylight, drier trails over the 630 m high point, and beds available without a fight. The route is open all year, and because it sits in Ireland's drier east, even March and October are realistic for experienced walkers.
Unlike Ireland's west-coast trails, the Wicklow Way gives you a long usable season. Its 129 km run from Marlay Park in Dublin to Clonegal crosses upland that catches 900–1,200 mm of rain a year — wet by most standards, but a full 20–30% less than Kerry — and no stage strays more than a couple of hours from a road. Here is how the year breaks down.
Spring (March–May): the underrated window
From late March the days stretch past 13 hours and the upland bog starts to firm up after winter. April brings lambing season in the southern farmland stages and gorse in full yellow bloom; May is statistically among the driest months in the east, per Met Éireann climate normals, with daytime temperatures of 13–16°C — close to perfect walking weather. May is our pick for the best month on this trail. The one caveat: spring forestry operations sometimes divert the route through Coillte plantations, so check for diversion notices before you set out.
Summer (June–August): long days, busy honeypots
June gives you 17 hours of daylight — enough to walk the whole Way in four big days if that's your thing, or to fastpack it with a vest-style pack like the Salomon ADV Skin 20. July and August are warmer (17–20°C) but wetter than May and noticeably busier: Glendalough alone draws around a million visitors a year, concentrated in summer weekends, and Wicklow Mountains National Park advises arriving at the monastic site before 10:00 to beat the coaches. On-trail crowding is mild — most visitors stay within a kilometre of the car parks — but beds in Roundwood, Glendalough and Glenmalure go fast. For summer 2026, book accommodation by early May.
Autumn (September–October): colour and quiet
September is the connoisseur's month: heather purple on the open mountain, school groups gone, sea-level temperatures still around 15–17°C. October trades some daylight (down to 10.5–11.5 hours by month's end) for golden beech and oak in the Glendalough and Clara Vale woods. The 22–24 km southern stages need an early start by mid-October — run your timings through the hiking time calculator and add 20% for short stops, because dusk in the forest comes early.
Winter (November–February): possible, but plan hard
The Wicklow Way stays officially open and snow rarely lies long below 500 m, but winter walking here means 8-hour daylight windows, ice on the railway-sleeper boardwalk over White Hill, and B&B options shrinking to the larger villages. If you go, split the route into 6–7 short stages, carry microspikes for the boardwalk sections, and treat the Djouce shoulder with respect in wind — gusts over 80 km/h are common on winter fronts. A stable, close-carrying pack such as the Deuter Aircontact Lite 45+10 or the weatherproof Zpacks Arc Scout 37L earns its keep in those conditions.
Which dates should you avoid in 2026?
Three kinds of dates work against you. Irish bank-holiday weekends — the first Mondays of May, June and August in 2026, plus the mid-March St Patrick's weekend — flood Glendalough and Roundwood with domestic visitors and double the pressure on the route's scarcest beds. Event days matter too: the Wicklow Way's race calendar sends hundreds of runners up the northern stages on certain weekends, and while walkers and runners coexist fine, B&Bs along the first three stages book out around those dates. Finally, watch the deer-rut weeks of late September and October in the uplands around Glenmalure — the trail stays open and safe, but Coillte and the national park occasionally post localised diversions, and stags on the path at dawn deserve a wide berth. None of these is a reason to cancel; all are reasons to book the specific night, not just the general week. A Tuesday start neatly sidesteps most of it — you cross the busy northern honeypots midweek and reach the quiet southern stages by the weekend.
How does the Wicklow Way's season compare to other Irish and UK trails?
It is the most season-proof of the lot. The Kerry Way effectively closes its remote stages from November to February as B&Bs shut; Scottish routes add midges from mid-June to August. Wicklow has neither problem — see our guide to the best time for the Great Glen Way for the Scottish contrast. If you only get one slot in 2026, take the last two weeks of May: dry trails, 16-hour days, and Glendalough before the summer coaches arrive.
Frequently Asked Questions
What is the driest month on the Wicklow Way?
May is typically the driest walking month in Ireland's east, with the Wicklow uplands receiving roughly 70–90 mm of rain compared to 120–150 mm in the wettest winter months. April and June are close behind, which is why the May–June window is the most popular time to walk the trail.
Can you walk the Wicklow Way in winter?
Yes — the trail is open year-round and rarely snowbound below 500 m. The constraints are 8 hours of daylight, ice on the White Hill boardwalk, and reduced accommodation. Winter walkers should plan 6–7 short stages, carry microspikes and a headtorch, and check forecasts for the exposed Djouce section.
How crowded is Glendalough in summer?
Very, around the car parks: the valley attracts on the order of a million visitors a year, peaking on July and August weekends. Through-walkers escape the crush quickly — within 1 km of the Upper Lake the trail is quiet — but should book Glendalough or Laragh beds well ahead and visit the monastic site before 10:00.
When does heather bloom in the Wicklow Mountains?
Bell heather starts in July and the dominant ling heather peaks from mid-August to mid-September, turning the open slopes around Djouce and White Hill purple. Early September combines the bloom with quieter trails, making it one of the most photogenic times to walk the Wicklow Way.
