Glendalough Guide: The Monastic Site, the Two Lakes and the Walking Trails
St Kevin's monastic settlement in the Wicklow Mountains — the Round Tower, the two lakes, the walking trails, and how to get there from Dublin without a car.

Wicklow's proximity to Dublin is what makes it work as a day trip destination — most of what's below is under an hour's drive from the city centre, though how easy it is without a car varies a lot from one site to the next.
The monastic site founded by St Kevin in the late 6th century, set beside two lakes in the heart of Wicklow Mountains National Park, and the single Wicklow day trip that's genuinely straightforward by public transport: St Kevin's Bus Service runs directly from St Stephen's Green North in Dublin, a journey of about 80 minutes each way, with continuous service on this route since 1927. See our full Glendalough guide for the walking trails, the visitor centre and current timetable links.
Getting there: St Kevin's Bus from Dublin city centre, or about an hour's drive.
A large landscaped estate near Enniskerry with terraced gardens looking toward the Sugar Loaf mountain, and a separate waterfall site a short drive away on the River Dargle — a single, dramatic 121-metre drop billed by the estate as Ireland's highest, though it's a close-run claim (a small number of remote waterfalls elsewhere are taller). House, gardens and waterfall are ticketed separately; check powerscourt.com for current admission and hours. Public transport is limited — a bus serves Enniskerry village, but the estate gates are still a walk from the village centre — so this is much easier by car or as part of an organised tour.
Getting there: Best by car (about 45 minutes from Dublin) or an organised day tour.
Rather than a single site, this is a route: the Old Military Road up over the Sally Gap, a mountain pass at around 500 metres, taking in the moorland views, Lough Tay (the "Guinness Lake," visible from roadside pull-ins on the R759 though not open to the public) and Glenmacnass Waterfall, an 80-metre falls with parking right at the top. Good as a half-day loop on its own, or combined with Glendalough if you're driving and have a full day to spend. See Things to Do in Wicklow for more on both stops.
Getting there: Car only — no public transport serves this route.
Pair these two for a gentler, garden-and-village day rather than a mountain one. Mount Usher Gardens at Ashford is a 20-acre riverside garden established in 1868, and Avoca village — about 20 minutes further south — is known both for its role as the filming location of the BBC series Ballykissangel and for Avoca Handweavers, a working weaving mill dating to the early 18th century. Both are best reached by car; public transport options are limited enough that they're impractical for a single day trip without one.
Getting there: Car recommended; roughly 1–1.5 hours from Dublin.
If you'd rather walk than sightsee, the Wicklow Way's first stage — from Marlay Park on the southern edge of Dublin to Knockree — is a manageable day walk on Ireland's oldest waymarked trail, reachable by Dublin Bus at both ends without needing a car at all. It's a genuinely different way to see the same mountains covered elsewhere in this guide, on foot rather than from a car window.
Getting there: Dublin Bus to Marlay Park; Dublin Bus back from Knockree.
Yes, if you have a car or are on an organised tour — the two are roughly 30–40 minutes apart by road. It's a full day once travel time is counted, and tight if you also want to walk one of Glendalough's longer trails. By public transport it's much harder, since the two sites have separate, unconnected routes from Dublin.
Glendalough is the one — St Kevin's Bus runs directly there from St Stephen's Green North in Dublin. Powerscourt, Mount Usher, Kilruddery, Avoca and the Sally Gap all have limited or no public transport, so they're easiest with a car or a day-tour operator that includes transport.
For the monastic site and the Lower Lake, yes — a few hours covers it. If you want to also walk the Spinc and Glenealo Valley route around the Upper Lake, allow a full day once travel time from Dublin is factored in.
