If you're not on the way into Dublin yet-it's not too late! Events are going on all day. There's no point me repeating all the details here because Pride has a great website http://www.dublinpride.ie/
But basically, the parade leaves The Garden of Remembrance at the top of O'Connell Street at 2pm, people gathering there now. It snakes down O'Connell Street and on to Trinity, down Nassau Street and into Merrion Square where there is to be a right good party from 3pm onwards with music food and generally just a lot of fine people having a good time.
All evening events that are going on are on the website so, have a great day, whether you are in the parade, watching from the street or joining in the fun in the square.
