A beautiful cascade, Poulanass takes its name from the Irish Poll an Eas: hole of the waterfall. Runners on the Wicklow Way and the Spinc Trail will find it hard not to stop and admire the falls. However, in ascent, you might be glad of the chance to rest for a moment.

The park is rectangular and surrounded by main roads on all sides. During the summer months, free concerts and theatre performances are regularly held there on weekends. Changes in traffic routing led to a drastic reduction in road traffic in 2004. A terminus of Line B of the new Dublin tram (Luas) is located directly on the western side of the park. Plans to excavate a large part of the park as part of the expansion of the Dublin Metro North Line have raised serious concerns that the character of the park could be irreparably changed by the associated interventions.
