Here is a pleasant walk where you have the choice of three routes. The highest part of the walk is at the entrance to the Powerscourt Estate (image 8) and the lowest part is where I suggest you leave your car at the junction of the Bray Road and Cookstown Road (image below)
The sequence of images is from the junction up the Bray Road, down the Cookstown Road and finally up Lovers Leap Lane.

The Bray Road is a busy road with heavy vehicles using it at times. There is a footpath along the entire route so you only have to contend with the sound. The river is mostly hidden by vegetation but glimpses of it can be seen at times.

The only structure left from a proposed railway line between Bray and Enniskerry. Some track was laid and this viaduct over the Dublin water mains was built. The speculator went bankrupt and the rails were quickly taken up by his creditors.

Scenes along the Cookstown Road

There is a junction on the lane with a side branch running downhill this will take you down to the river and to this scenic gorge.

The lane reduces to an uphill track and a side track will take you to the Lovers Leap (image above right).

The entrance to Lovers Leap Lane from the R760. Between this location and location of the last images is a narrow track with an overgrowth of briers on either side. Hopefully when you travel through they will have been cut back otherwise you may have to return the way you came.
