Millennium Park, Blanchardstown, Dublin 15
Good park loads of space, nice grind boxes and rails, flatbanks and hips are really good, never gets too crowded either.
Bit slippier than some other concrete parks, bit of a steep bit where ramps meet ground. The fences...
Other users, despite it being fenced in, keep an eye on your stuff, there's a decent food selection down at the shopping centre, too.
