Steeped in Irish folklore and history, Glendalough is one of Ireland's most spectacular destinations. From the valley floor, you are treated to awe-inspiring views of the Upper lake over to the Glenealo gap. Once you ascend the trail, the views of the lake and the valley change to to give you another perspective.
The looped trail is approx 7km long and has about 236m of elevation. It is well marked and generally well maintained. The car park in the valley can get quite busy in the summer months, but alternative car parks are available nearby the trail head. Dogs are allowed on the trail, but must be kept on a leash. The trail is family friendly, but as there is a good bit of elevation, it isn't recommended for small children or strollers.
