Dublin is not representative of Ireland! maybe go to cork, go to some countryside spots, redbooks in wexford is amazing, a Wicklow mountain? If you’re really stuck in Dublin then uhh go to the lighthouse or ifi for a good movie!
Fly into Cork which is amazing and has a great food scene, so much history around the independence movement (why did they take Michael Collins‘s hat off display???????) then head to the Beara for gorgeous country side and lovely culture. I did a retreat at Dzogchen Beara and can’t wait to go back and spend more time exploring. Ballymaloe is a must - would love to try their summer cooking course.
