The exquisite 19th century Johnstown Castle is nestled within fifty acres of ornamental grounds. Stroll through the wooded grounds with over two hundred different kinds of trees and shrubs or relax by the castle lakeside with its Gothic towers and waterfalls. Ramble along the Castle lake terrace walk lined with statues to the Garden lake. Both lakes are home to a wide range of waterfowl - mute swans, water hens, little grebes and heron. 

Pass through the Devil's Gateway into the walled ornamental gardens and hothouses. This hidden paradise provides a dazzling, colourful array of flowering plants. The sunken Italian Garden contains a shaded picnic area where one can sit and watch the peacocks strut by. Another attraction is the ruin of a medieval tower house called Rathlannon Castle. Please note that unfortunately Johnstown Castle itself is not open to the public.
