This trail is one of the more popular hiking trails in the Dublin Mountains and is the Gateway to the Wicklow mountains. The 3.6km trail follows the service road from the main Three rock woods car park to the top of Three rock mountain. Here, you are treated to stunning views over Dublin bay, the City and around towards the Wicklow mountains. The Summit has plenty of areas to take a photo or to have a lunch with a view over Dublin. The trail is family friendly and dogs are allowed on the trail (on a leash). The mountain also has several mountain bike trails, so caution is advised. The hike should takes on average 2 hours to complete. Main Photo:Joe King
