Hpurple has previously suggested a scenic walk to Dalkey, which I would like to include in our trip to Dublin in May. We will be taking the DART. I'm not good at judging distances, so any ideas how long a walk would be that might take in Sandycove to Dalkey and then maybe continuing on by foot or DART to Killiney as well. Or on the other hand would it be best to reverse the route and start in Killilney? Is there a marked trail or road way or board walk? Thanks for any specifiic directions you can give me!
