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.

Here the Wicklow Way long-distance trail skirts the mountain of Stookeen. Standing 420 metres (1,378 feet) high, the summit affords great views of the surrounding area. The official route runs around the southern edge, but it's a rewarding excursion to the top and back.

At 509 metres (1,670 feet) Robber's Pass Hill is the summit of this lovely area of heathery moorland. The actual summit is slightly off the Wicklow Way, but it's close by and worth the detour.

As you ride through the mountainous scenery look out for the Sugarloaf in the distance. At 1,811 feet (552 m), it's a prominent feature in the western Wicklow landscape. The Maulin Loop is do-able on a MTB or gravel bike but take care on the descent.
