Overview
Glendalough — from the Irish Gleann Dá Loch, meaning 'Valley of the Two Lakes' — is one of Ireland's most visited heritage and natural landscapes. Situated in County Wicklow within Wicklow Mountains National Park, it sits roughly 50 km south of Dublin city centre.
The site is defined by two glacially formed lakes, the Upper and Lower Lough, set beneath steep wooded valley walls. Above and around the lakes stands a remarkably intact early Christian monastic complex founded by St Kevin in the 6th century. The Round Tower, cathedral ruins, and several smaller churches have survived more than a thousand years and remain the centrepiece of any visit.
Despite its small size — Glendalough itself is not a town but a designated heritage area with a small visitor hub — it draws significant visitor numbers, particularly on summer weekends. Planning around busy periods and arriving early in the day makes a meaningful difference to the experience.
Before You Go
Visas
Glendalough is in the Republic of Ireland, which is not part of the Schengen Area. Entry requirements vary by nationality. Check TravelerPulse's Visas section and the Irish Naturalisation and Immigration Service (INIS) website for current, authoritative guidance before travelling.
What to pack
- Waterproof jacket and layered clothing; weather in the Wicklow Mountains changes quickly year-round
- Sturdy walking shoes or hiking boots if you plan to use the trail network
- Cash or card — verify locally which facilities accept cards, as coverage can be limited in remote areas
- A printed or offline map of the trail routes is advisable as mobile signal is unreliable in the valley
Health and accessibility
The monastic site and lower valley paths are reasonably accessible on firm, level ground. Upper lake trails and mountain routes involve uneven terrain and gradients unsuitable for pushchairs or limited mobility. Verify current accessibility conditions with Wicklow Mountains National Park before visiting.
Getting There
From Dublin
Glendalough is approximately 50–55 km south of Dublin city centre via the N11/M11 and R755 through Laragh. The drive typically takes around one hour depending on traffic, though summer and bank holiday weekends can add considerable time.
Public transport options exist but are limited. St Kevin's Bus runs a scheduled service between Dublin city (outside the Glendalough Hotel at St Stephen's Green) and Glendalough. Verify current timetables, prices, and booking requirements directly with the operator, as schedules are subject to seasonal change.
There is no direct rail link to Glendalough. The nearest train station is at Rathdrum or Wicklow town, both requiring an onward taxi or bus connection. Verify connections locally before travelling.
By car
A car park serves the visitor centre and monastic site. A separate car park is located at the Upper Lake. Both fill quickly on summer weekends and bank holidays; arriving before 9 a.m. is strongly advisable. Check Wicklow Mountains National Park's official channels for any parking fee or permit changes.
Getting Around
Glendalough is compact and explored almost entirely on foot. The valley floor connecting the visitor centre, monastic site, Lower Lake, and Upper Lake is walkable in a short time on well-maintained paths.
A network of waymarked trails extends into the surrounding mountains, ranging from easy lakeshore loops to longer, more demanding routes. Trail maps are available at the National Park visitor centre. Cycling is permitted on some roads within the valley but the main heritage site and footpaths are pedestrian only.
There is no local bus or shuttle between points within the valley. If driving, you can move between the main car park and the Upper Lake car park by road.
Where to Stay
Accommodation within Glendalough valley itself is extremely limited. The Glendalough Hotel is the principal option on site; booking well in advance is essential for summer and bank holiday weekends.
The surrounding area — Laragh, Rathdrum, Wicklow town, and Blessington — offers a broader range of guesthouses, B&Bs, and self-catering properties. Wicklow town, approximately 30 km away, has the widest selection and good transport links.
Many visitors choose to stay in Dublin and make Glendalough a day trip. This is practical but means accepting a full day out, particularly if relying on public transport. Verify all accommodation options and availability through established booking platforms or directly with properties.
Things to See & Do
Monastic City
The monastic complex is the primary cultural attraction. Key structures include the 30-metre Round Tower (one of the best preserved in Ireland), the Cathedral of St Peter and Paul, St Kevin's Kitchen (a small oratory with its own miniature round tower), and Reefert Church near the Upper Lake. Entry to the grounds is free; the reconstructed gatehouse and most exterior structures can be visited independently.
Visitor Centre
Wicklow Mountains National Park's Glendalough Visitor Centre offers interpretive exhibitions on the monastic history and natural environment of the valley. An admission fee applies; verify current prices and opening hours on the National Parks and Wildlife Service (NPWS) website before visiting.
Walking and Hiking
The trail network is the main draw for many visitors. The Green Road and Lakeshore Paths offer easy, flat walking. The Wicklow Way long-distance route passes through the area. More challenging routes ascend to Camaderry and the surrounding ridgelines with panoramic views. Always check conditions and carry appropriate gear.
Wildlife and Nature
The valley supports red deer, Sika deer, red squirrel, and a variety of upland bird species. The oak woodland flanking the Upper Lake is particularly noted for birdlife. The lakes and river also hold populations of brown trout.
Food & Drink
Food and drink options at Glendalough itself are very limited. The Glendalough Hotel, located at the entrance to the valley, has a bar and restaurant open to non-residents; verify current hours and service directly with the hotel.
The nearby village of Laragh, roughly 1 km from the monastic site, has a small number of cafes and a general store. Options here can become busy in summer. The village of Roundwood, a short drive north, and the town of Wicklow to the east offer a wider range of restaurants and pubs.
If planning a full day of hiking, bringing your own food and water is strongly recommended. There are no refreshment facilities on the upper trails.
Practical Information
Money
The currency is the Euro (€). There are no ATMs within Glendalough valley. The nearest reliable ATM access is in Laragh or further afield in Rathdrum or Wicklow town. Carry sufficient cash for the day.
Mobile signal
Coverage in the valley and on the mountain trails is patchy to non-existent with most Irish carriers. Download offline maps, trail guides, and any emergency contacts before leaving areas with reliable signal.
Emergency services
The all-Ireland emergency number is 112 (or 999). Mountain Rescue can be alerted through this number. Be aware that giving an accurate grid reference or landmark when reporting an incident in the mountains is important; carry a map and know your location.
Leave No Trace
Glendalough is a protected natural and heritage area. Stick to marked trails, take all litter out, do not climb on or damage the historic structures, and keep dogs on leads in areas where this is required.
Safety
The most significant safety considerations at Glendalough relate to mountain walking rather than personal security. Weather in the Wicklow Mountains can deteriorate rapidly and trails can be slippery, boggy, or poorly marked in poor visibility. Do not underestimate higher routes even if conditions look benign at valley level.
Tell someone your planned route and expected return time before heading onto the mountain trails. The standard Irish Mountain Rescue Association advice applies: carry map, compass, waterproofs, food, water, and a fully charged phone.
The monastic ruins are protected national monuments. Climbing on walls or structures is prohibited and can result in damage to irreplaceable historic fabric as well as personal injury.
General personal safety concerns are low. The site is well visited and staffed during opening hours. Take normal precautions with valuables left in parked cars.
