Arbitrary coupling alert! Yvonne off Fair City joins former snooker champion and fellow Dubliner Ken Doherty for a walk across the Mountains in this last instalment of the random show. Sure why ever not. The walk starts at the Luas terminus in Tallaght and ends at the DART station in Shankill. Don't worry, they walk it - it's a new trek across a 40km path called The Dublin Mountain's Way. The first of many important landmarks which Ken and Ciara will encounter on their walk is Bohernabreena Reservoir... moving on, among the many famous, or infamous, names which crop up along the Dublin Mountains Way is the notorious Hellfire Club. It is a famous landmark which can be seen from a long way away and even the very sight of it is foreboding.
