St Kevin's Bus, which passes through Annamoe (home village of Glendalough House), runs a daily service between Dublin and Glendalough. Simply jump aboard and let the driver know when you want to get off! Please visit the St. Kevin's Bus website for details.
Public busses don't service Annamoe. However, hop on a public bus to Kilmacanogue, Greystones, Newtownmountkennedy, Ashford or Wicklow and a cab will!
