I've mentioned the Dublin City Council Let's Walk & Talk initiative in the past and they've just released their summer schedule. As well as their extensive usual timetable, a couple of highlights this season include:
A Day of Infamy & Heroes - the North Strand Bombings
Tuesday, 31st May @ 12 noon
Commemorating the bombings in conjunction with the 70th anniversary plans.
Dublin's Little Jerusalem
Tuesday 24th May @ 2pm
Damn them! They've run this before and I'm really keen to go on it but it's always on weekdays when I can't take time off work. This includes a visit to the Irish-Jewish Museum in Portobello.
East Wall - A Proud Community
Monday 13th June @ 1pm
Further details from their website. All events are free and do not require booking.
