There is a moment on the road from Dublin to Wicklow when the city falls away behind you and the landscape ahead opens up into something unexpected. The traffic thins, the houses thin, and the hills ahead begin to rise, green and purple with heather, broken by stone walls and dark pine forests and sudden views down into valleys that look as though they have barely changed in a thousand years. It happens within about forty minutes of leaving the city centre, and it is the moment that most guests on Planet Dublin Tours’ Glendalough and Wicklow Mountains private tour first realise just how close this extraordinary landscape is to Dublin.
By the time the day is over and they are back in the city, with photographs of ancient round towers and glacial lakes on their phones and the scent of mountain air still in their jackets, most people say the same thing: they had no idea Ireland looked like this.
County Wicklow is one of the most scenically varied counties in Ireland. Known as the Garden of Ireland, it encompasses dramatic mountain terrain, deep glacial valleys, ancient oak forest, fast-running mountain rivers, and a coastline of dramatic cliffs and sandy beaches. From the highest points in the Wicklow Mountains, you can see across five counties on a clear day, with Dublin Bay visible to the north and the Irish Sea glittering to the east.
Within this landscape sits Glendalough, literally “the valley of two lakes” in Irish, one of the most important and atmospheric early Christian sites in the country. Founded in the 6th century by a hermit monk named Kevin, the monastic settlement grew over several centuries into one of the great centres of learning in early medieval Europe. At its height, pilgrims travelled from across Ireland and Britain to study here or to be buried in the shadow of its churches. The community survived Viking raids, Norman invasions and eventual dissolution, and today its ruins, a remarkable intact round tower, a cathedral, several smaller churches, a priest’s house and an ancient graveyard, are among the best-preserved in Ireland.
Together, the Wicklow Mountains and Glendalough offer something that is rare in day tour geography: a destination that is simultaneously spectacular on a purely visual level and rich enough in history and narrative to sustain a full day of exploration and storytelling.
Spring is one of the finest seasons to visit Wicklow. The countryside is at its most vivid green, the kind of saturated, almost unreal green that gives Ireland its reputation, because the spring rains have fed weeks of growth and the whole landscape is in the first fresh burst of a new season. The trees in the Glendalough valley are in early leaf, the forest floors are carpeted with wood anemone and wild garlic, and the mountain streams are running fast and clear after winter.
The light in April & May is also often exceptional, longer days, lower sun angles in the morning and evening, and a clarity to the air that makes the mountain views exceptionally sharp. For photography in particular, the Wicklow Mountains in Spring frequently produce the kind of images that look too beautiful to be real.
Visitor numbers are also considerably lower than in peak summer months. In July and August, Glendalough can attract large numbers of coach tour visitors at certain times of day. In April and May, the valley is quieter, and a small private group can explore the monastic site in something closer to the peace that the monks themselves would have known.
The Glendalough day tour from Planet Dublin Tours begins with a hotel meet and greet in Dublin, with your registered Fáilte Ireland guide ready to orient you for the day ahead before you even leave the city.
The route south takes you through the Dublin Mountains, which rise immediately behind the southern suburbs of the city. This is a different kind of landscape from Wicklow proper, more open and windswept, with panoramic views back across Dublin Bay and northward along the Irish Sea coast. Your guide will point out landmarks in the city below and explain the geography of the Dublin and Wicklow hills, which were shaped by the same glacial forces that carved the Glendalough valley.
Crossing from County Dublin into County Wicklow, the route descends into the Vale of Avoca, a wooded river valley that inspired the 19th-century poet Thomas Moore, before climbing again into the Wicklow uplands. The scale of the mountains here is genuinely impressive. These are not gentle hills; they are a proper mountain landscape, with open moorland on the upper slopes and dark conifer forests on the lower hillsides, traversed by fast-running rivers and dotted with small farms whose fields drop steeply toward the valley floors.
Before reaching Glendalough, the tour typically stops at viewpoints over Wicklow National Park, where you can take in the full sweep of the landscape and understand the geography of the valley you are about to enter. These stops are not rushed. There is time to photograph, to breathe the mountain air and to absorb the scale of what is around you.
The approach to Glendalough is one of the finest arrivals in Irish day-trip geography. The valley narrows as you descend, the steep sides rising dramatically on both sides, and then the monastic site comes into view, the round tower standing above the treetops, its cone-shaped cap unmistakeable against the sky.
The round tower at Glendalough is one of the most photographed structures in Ireland. Built somewhere between the 10th and 12th centuries, it rises approximately 30 metres and was designed simultaneously as a bell tower, a landmark for pilgrims navigating the mountains, and with its doorway set high above the ground, a place of refuge when Viking raiders came up the valley. The combination of these functions in a single elegant structure is a characteristic of early Irish monasticism that your guide will explain with the kind of detail and storytelling that transforms a ruin from a picturesque backdrop into a living part of history.
The cathedral is the largest of Glendalough’s many churches and dates from the early 12th century, though the site on which it stands was used for worship from St Kevin’s time. The quality of the stonework, the scale of the structure and the remarkable state of preservation all reward close attention. The surrounding graveyard, still in active use for the local community, contains carved stone crosses and memorials dating back centuries, and your guide can navigate you through the layers of history embedded in it.
Beyond the principal enclosure, forest walking trails follow the banks of the two glacial lakes, the Upper Lake and the Lower Lake, through one of the most beautiful stretches of ancient oak woodland in Ireland. The Upper Lake in particular, enclosed by steep mountain slopes on three sides, has an atmosphere of great stillness. This is the place where St Kevin is said to have lived as a hermit before the monastic community grew up around him, and standing at the water’s edge it is easy to understand why he chose it.
Your guide will share the full story of Glendalough, Kevin’s life, the growth of the monastery, the Viking raids, the political turbulence of the medieval period, the 16th-century dissolution and the subsequent centuries of pilgrimage that continued long after the monks had gone. It is a narrative that spans fifteen centuries and connects directly to the landscape surrounding you as you hear it.
The Planet Dublin Tours Glendalough and Wicklow Mountains private day tour is a nine-hour experience departing from your Dublin hotel. It includes a hotel meet and greet, a registered local tour guide, luxury air-conditioned private transport for up to seven guests, scenic mountain viewpoints, the Glendalough Monastic Site visit, forest walking trails beside the lakes, and water and snacks throughout the day.
Lunch is flexible. Your guide will recommend a traditional Irish pub lunch in the nearby village of Laragh, which sits at the entrance to the Glendalough valley and provides a comfortable and authentic setting for the midday break. There are also options for a picnic stop beside one of the lakes if your group prefers it. The tour is private. There are no other guests, no shared schedule, no waiting for strangers. The day is entirely organised around your group.
The Glendalough and Wicklow Mountains tour consistently attracts a wide range of guests, and it works well across a variety of travel styles and interests.
It is particularly popular with first-time visitors to Ireland who want a comprehensive introduction to the country’s natural landscape and early history in a single day. It is equally well suited to visitors with Irish heritage connections, many guests on this tour are exploring ancestral links to County Wicklow, and the guide can incorporate local history relevant to specific areas if you have particular family connections in the region.
Couples who want a romantic and scenic day away from the city find the valley atmosphere and forest walks ideal. Families appreciate the mix of genuine outdoor adventure, the mountain scenery and lakeshore paths, with a substantive heritage experience that gives the day some intellectual texture alongside the fresh air and exercise. Mature travellers who want to experience dramatic natural scenery comfortably, without the physical demands of independent hiking, find the private vehicle and relaxed pace a genuinely comfortable way to access a landscape that repays the journey richly.
Glendalough is one of the most popular day trip destinations from Dublin, and as a result it appears on the itinerary of many large coach tours. It is worth being clear about the difference in what those tours and a Planet Dublin Tours private experience actually deliver.
A large coach tour to Glendalough typically involves a vehicle carrying between thirty and fifty people. It follows a fixed route and a fixed timetable. The stop at Glendalough is usually between one and two hours, which is enough to walk through the main monastic enclosure but not enough to reach the Upper Lake or spend time on the forest trails. The guide addresses the whole group at once, and the ratio of passengers to guide makes any kind of personalised storytelling or responsive conversation effectively impossible. The experience of arriving at Glendalough on a summer coach tour is also, frankly, one of being in a crowd, at the peak of the season, the main site can feel like a busy car park with ruins in the background.
A Planet Dublin Tours private experience is a different category of outing entirely. The vehicle holds a maximum of seven guests. The schedule is flexible. There is time to linger at the Upper Lake, to walk further along the valley if the group wants to, to stop at a viewpoint for longer than was strictly planned because the light is doing something spectacular. The guide talks with you rather than at you. And the quality of the storytelling, the depth of knowledge about the valley, its history, its ecology, its meaning in the broader context of Irish history, is something that a coach tour guide managing fifty people simply cannot provide.
