Palmerston Park is a treasure of a park that admittedly I lived right next to and didn't notice it was there until about 7 months in. From the outside it's deceptviely small looking, but once you get inside you'll find that it's quite large and there's many different sections and areas.
If you ever get a sunny spring day it's perfect place to sit outside and relax in the sunshine. There's a footpath that goes around the perimeter of the park. It's excellent if you're looking for a change in your walking routine or somewhere safe for the kids to ride their bikes around. I've never seen the park crowded which is perfect because you're always sure to get a spot on the grass, which can't be said for St. Stephen's Green.
And also a nerdy history note, Palmerston Park was the headquarters of James Butler, 1st Duke of Ormonde, during the Battle of Rathmines in 1649. When Butler and his troops were defeated, the route was opened for Cromwell to invade the rest of Ireland ... ok so maybe not a selling point for the park, but still something to think about when you're bikin around. read more
