|Subject: Re: A week in Dublin|
One place near Dublin that hits all your goals is the ancient monastic community of Glendalough in the Wicklow Mountains. You can get a day-long bus tour from Dublin to there, which also goes by James Joyce's Martello tower and Thomas Moore's Vale of Avoca. The bus stays at Glendalough for a long lunch, but I would recommend bringing your own or skipping lunch altogether so that you would have time to hike to the lakes and follow some trails along the mountainside.
