Glendalough by Car:
Take the N11 which is the main road south out of Dublin. Just passed the exit for Bray there is a junction for the R755 which will be sign posted for Roundwood. Stay on this road for about 20 – 30 minutes until you reach Laragh. Going through the centre of Laragh take the R756 which is sign posted to Glendalough. From Laragh it is only about ten minutes to Glendalough.
At Glendalough there are three main car parks, one on your left which is first this is the visitors centre. The next is just a little further into the village behind the hotel and the last is at the end of the road a few minutes further on – the last one is best if you only intend to go walking. I have found all the car parks safe, though I never leave anything in view, everything goes into the boot of the car.
There are more interesting routes to and from Glendalough, for example over Sally Gap, my favorite, or the Wicklow Gap – however I would suggest buying a map, (Ordnance Survey Discovery Series 56). Traveling back by the Sally Gap affords great views over the top of Dublin from the Wicklow Mountains and is worth the drive.
Glendalough by Bus:
St Kevins Bus Service
The main bus service to Glendalough from Dublin is the St Kevins Bus Service. Their web site is here They collect in Dublin at 11.30am on Dawson Street opposite the Mansion House, two minutes or less from Stephens Green. Winter they return to Dublin at 16.30 with exceptions for weekends and bank holidays. In summer they leave Glendalough a little later. I recommend checking their web site for current time table. The current fare is €18 return for an adult from Dublin to Glendalough. I have never used this service therefore I cannot comment on times and service. One small problem, from my view point is that there may not be a lot of time to walk the beautiful main route round the lake – but if you do not have a car that’s life.
