Powerscourt Waterfall, 121 metres

The River Dargle drops 121 metres down the hillside: it is the tallest waterfall in Ireland. It is within the Powerscourt estate, but about six kilometres from the house and gardens, and has a separate entrance fee (€7.50 according to the official website). At the bottom there are meadows to run around in, a playground, picnic tables and space for barbecues, and the car park is free.

Sika deer live in the woods, a Japanese species brought here by the seventh Viscount Powerscourt in 1858. There is no public transport here: go by car or by taxi from Enniskerry, or walk up the Crone Woods route to the Ride Rock viewpoint, which sees it from above.
