Tips from the Community
The Glenmacnass Waterfall cascades 80–100 metres down several broad steps into a carved U‑shaped valley, one of the wildest landscapes in the Wicklow Mountains. From the R115, you have a frontal view of the granite ledge over which the water falls, with open moorland, peat slopes, and the river winding its way towards Laragh.

The waterfall plunges in multiple stages, 80–100 meters, down a wide granite ledge. The combination of steep walls, open highlands, and the winding river below makes this one of the most dramatic panoramas in the entire R115 corridor.

Sally Gap, one of the highest and most open crossroads in the Wicklow Mountains. Here, the R759 and the Old Military Road (R115) intersect at over 500 meters altitude, in the middle of a vast moorland and heath landscape without buildings or shelter. The panorama is a full 360°: the dark bogs of Liffey Head Bog, the flanks of Kippure, the valleys towards Glencree, and the long, empty Military Road that runs like a pencil line through the highlands. This location is world-famous as a backdrop for films and series such as Braveheart, Vikings, and P.S. I Love You.

You are here on one of the most characteristic sections of the Old Military Road, built between 1800 and 1809 by the British Army to control the Wicklow Mountains after the 1798 Rebellion. This section of the L1013 runs across an open high plateau with wide, rugged views towards Glencree, Kippure and the northern Wicklow Mountains.

A modern cable-stayed bridge from 2009, designed by Santiago Calatrava, recognizable by its large white arch and 31 cables that together evoke the shape of an Irish harp. The bridge connects Sir John Rogerson’s Quay with Guild Street in the Docklands and can rotate up to 90° to allow ships to pass. It is one of the most photogenic spots along the Liffey, especially in the evening light with its reflections on the water.
