Glendalough Walks Guide: Trails, Tips & Wicklow Way

Walking in Glendalough: Trails, Tips, and the Wicklow Way Experience

There's something about Glendalough that keeps walkers coming back. Maybe it's the way sunlight catches the lakes or how the ancient Round Tower appears through morning mist, or perhaps it's simply knowing that people have sought out this valley for over a thousand years. Most visitors breeze in on a day tour, ticking off the monastic ruins before heading home. But if you're reading this Glendalough walks guide, you're probably after something richer — a walk that lingers long after you've left the valley.

Whether you're plotting a day hike, tackling a stretch of the Wicklow Way, or dreaming up a longer adventure, this walking guide to Glendalough is for you. Here's what you need to know to make the most of the walking routes in Glendalough.

Best Walks in Glendalough Valley: Your Essential Guide

Glendalough isn't just a single path; it's a collection of walking routes, each offering its own flavour of Wicklow magic. Here's a quick run-through of the best walks in Glendalough valley:

Spinc Walk Glendalough: The Must-Do Ridge Walk

The Spinc walk in Glendalough is the iconic route here, and for good reason. It's a 9km loop that climbs sharply from the Upper Lake car park, follows a raised boardwalk above the treetops, and serves up jaw-dropping views across both lakes and out to the Irish Sea. Allow three to four hours, and brace yourself— the ascent is no joke, and the ground can be slick after rain (which, in Wicklow, is most of the year). Decent walking shoes are a must.

Most people walk the loop clockwise for a gentler descent, and you'll want to linger at the top: on a clear morning, with clouds lifting off the lakes, it's nothing short of spectacular.

Glenealo Valley Walk: Quiet History, Wild Beauty

Venture beyond the Upper Lake and you'll find the Glenealo Valley walk, a wilder, less-trodden landscape. The path weaves past the remnants of a 19th-century mining operation, with the river your constant companion. It's quieter and feels more remote — a real treat if you crave a sense of history beneath your boots. Combine it with the Spinc for a challenging 12km loop if you're feeling ambitious.

Glendalough Lower Lake Loop: Gentle Strolls and Timeless Stories

If you're after something less demanding, the Glendalough Lower Lake Loop is a 3km meander through woodland and along the water's edge. You'll pass St Kevin's monastery, the Round Tower, and several mediaeval churches — making this perfect for families, first-time visitors, or anyone hoping to soak up the valley's rich past as much as its hills. You don't need to be a serious walker to enjoy these Glendalough walking routes, and this one proves it.

Glendalough to Laragh: A Woodland Wander to the Pub

A short, sweet connector trail links the visitor centre with Laragh Village — a pleasant 30-minute stroll through woodland that ends at a cosy pub or café. After the spin, it's just what the doctor ordered.

Glendalough on the Wicklow Way: A Trail Landmark

Glendalough isn't just a destination — it's a milestone on the Wicklow Way, Ireland's oldest long-distance trail. Stretching 131km from Dublin's Marlay Park to Clonegal in County Carlow, the Wicklow Way winds through mountains and forests, with Glendalough serving as a natural, much-anticipated pause. For most walkers, the arrival into the valley – lakes sparkling, the Round Tower standing sentinel – is a trail highlight that's difficult to forget.

If you're tackling the Wicklow Way, Glendalough is the perfect place to rest, refuel, and soak up the valley before heading south toward Tinahely and beyond. Our walking holidays often stop here overnight, and trust us — it's the stage people remember most.

Glendalough Trail Tips: When's the Best Time to Walk?

May and September: These are the golden months. Long days, gentle light, and manageable crowds. May brings bluebells and the greenest hills; September brings golden light and tranquil mornings.
Summer (June–August): Beautiful, but busy. Car parks fill fast, but early risers will find the trails quiet even at the height of July.
Autumn and winter: Amber woodlands, copper leaves, and silvery winter light. Trails are muddier and days are short, but the valley is blissfully empty — perfect for seasoned walkers.
Avoid bank holiday weekends unless you're out at dawn. The car parks and visitor centre can get genuinely busy.

How to Visit Glendalough Without a Car

No wheels? No problem. St Kevin's Bus runs daily from Dublin's St Stephen's Green, dropping you at Glendalough in about 90 minutes. It's reliable, affordable, and popular with both locals and hikers. Check schedules at stkevinbus.com, especially in summer when seats go quickly.

You can also walk between Glendalough and the surrounding area on foot, making point-to-point walks practical. For Wicklow Way hikers, there are bus connections at various stages along the route — we're always delighted to help guests figure out the logistics.

Where to Stay: Rest Up, Refuel, Repeat

Laragh, just five minutes from the visitor centre, is the main hub for walkers. Expect friendly guesthouses and B&Bs that know how to handle muddy boots and early breakfasts. Book ahead for summer and bank holidays. There's also a hostel in Glendalough itself — and a few self-catering options nearby if you're staying a bit longer.

For those walking the Wicklow Way with us, we handpick and personally vet every accommodation along the route. Your luggage travels ahead, so all you need to carry is your sense of adventure (and maybe a snack or two).

Before You Go: Essential Glendalough Trail Tips

Wear proper footwear. Trails can be wet even in midsummer. Boots or trail shoes are essential.
Arrive early. The Upper Lake car park fills by mid-morning on weekends.
Check the weather. Wicklow's weather can change quickly. A lightweight waterproof is handy year-round.
Bring water and snacks. Once you're out on the Spinc or in the Glenealo Valley, options are scarce.
Respect the wildlife. Stay on marked trails, keep dogs under control, and leave no trace. The valley is part of Wicklow Mountains National Park for a reason.
