Druids - what a fine golf course! If you play this is a good one to get out on! You are at the base of the Wicklow Mountains - lots of little towns to explore - ask for "Ballykissangel" - village of Avoca - very quaint and lots of wee places to stop on the way (Pubs and the like). Go to Greystones and Bray - lovely wee towns - and if it is still there a great chippy on Greystons's shore front. Powerscourt House to the south is beautiful gardens with the tallest waterfall in Ireland. If the weather is good - no finer place to be!
If you are in Dublin, make sure you drink at either The Porter House or Messr Maguire. Both microbreweries and good places to drink. Lots of silly tourist places in Temple Bar of course...but the Guinness Tour is well worth it - even just for the view of Baile atha Claith from the top.
If you do get north of Dublin on the coast (end of the northern DART line) Howth is a great place for a bracing walk of the Howth Head. Great scenery! Eat the Bloody Stream (below the Dart Station) for great craic and seafood. Beshoff Bros may be the fish and chip shop...but expensive for what it is!
If you can drive - head out to the wee villages along the Royal Canal. I used to live 7 miles from the famous K Club in a little village called Kilcock. Lovely wee town, friendly folks...and seven pubs. I miss the craic at Murphy's of an evening.
Ireland is a great place to eat out and drink...smoking ban! Fantastic. Enjoy your stay in possibly one of the most beautiful places in the world!
