Make sure you bring a camera to capture the flowing cascades of Powerscourt Waterfall. If it's raging, you may be able to feel the mist on your face.
This cascade of water is often on the itineraries of travelers to Enniskerry. But Powerscourt Waterfall isn't the area's only highlight. Powerscourt Estate, Sugarloaf Mountain, and Killruddery House and Gardens are some other interesting sights nearby.
