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.

Luggala Trailhead Parking Area Small parking area on the north side of Luggala, starting point for the short but steep hike to the viewpoint over Lough Tay. Direct access to open heathland and panoramic views.

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.

Did the loop today bottom part was very wet, boggy under foot so make sure you were good footwear. Climb up Djouce was straight forward but the loop was difficult.

An excellent place for a pitstop. There is a small courtyard for storing one or two bikes and sheltered outside seating area. Great food but quite pricey
