Glendoo Mountain

About Glendoo Mountain

Sitting on the border between Dublin and Wicklow, this broad, heather-clad dome offers a quintessential Dublin Mountains experience. Often overshadowed by its neighbor Prince William's Seat, the summit provides a quiet vantage point over the Glenasmole Valley and the sprawling suburbs of the capital, accessible via the forest tracks of Cruagh Wood.
