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.

Formerly an important shipping stop-off before Dublin, Maynooth Harbour is now used mostly for leisure purposes. Known locally as Dukes Harbour, it lies close to the bustling university town of Maynooth.

Gravale is a 718-metre (2,356 ft) summit on the central spine of the Wicklow Mountains range and part of the Mullaghcleevaun massif. It's easily accessed from Sally Gap on the R759 after visiting Carrigvore. The summit itself is not prominent to qualify as a Marilyn, but such classifications fade in importance on a clear day, when you're treated to splendid Wicklow Mountains scenery.

The gravel/dirt/pine needle covered forest trails here are great to walk or cycle.

Slievethoul and Lugg are hills on the western edge of the Dublin mountains. There are nice walking trails around each or, if you have time, the area lends itself to a longer figure of eight loop to walk both.

Kilcock sits right on the Royal Canal Greenway, making it an ideal place to break up your ride. The harbour is a scenic spot to pause, with cafés just a few pedal strokes from the water. From here you can choose to head east towards Maynooth and Dublin or west towards Enfield and Mullingar, both on flat, well-surfaced paths.
