Vallymount is located approximately 32km from Dublin city centre.

Valleymount is at an average elevation of 198m above sea level and is situated on the R758 regional road. The village is on a land spit created by the flooding of the River Liffey and its primary tributary the King's River in the late-1930s and early-1940s for the Poulaphouca Dam project. The Poulaphouca project now supplies water to the Greater Dublin Area, and electricity to the ESB national grid.

It is serviced by the Dublin Bus 65 route which connects to Dublin twice daily (Mon - Fri).

The Valleymount Spur of St Kevin's Way, the pilgrim route to the ancient monastery site at Glendalough runs through Valleymount village. Another spur runs from the nearby village of Hollywood to Glendalough.

Vallymount neighbours the villages of Hollywood, Ballymore Eustace, Blessington, Ballyknockan and Lacken.

The townlands in the area of Valleymount include: Ballyknockan, (The) Togher, Monamuck, Valleymount (or Cross), Humphrystown, Lockstown Upper, Lockstown Lower, Baltyboys Upper, Baltyboys Lower, Rathballylong, Annacarney, Blackditches Upper, Blackditches Lower, Carrigacurra, Lugnagroagh, Tulfarris, Granabeg Upper, Granabeg Lower, Knocknadruce and Knocknadruce Upper. Nearby (to the NE) is the 'lost' townland of Ballinahown which was completely flooded by the Poulaphouca project in the late-1930s and early-1940s

The most notable building is St. Joseph's Catholic Church. Built in 1803, to which a porch extension was added around 1835, the 'Mexican style' of the church is attributed to design ideas brought home by Irish emigrants returning from New Mexico, and adapting the style to the local area. The church features stained glass windows by Harry Clarke, a leading figure in the Irish Arts and Crafts Movement and art students from Dublin's Art colleges sometimes visit the church to see the windows.

The pub was established around 1836, and changed owners. The current proprietor took over the family business in 1985 and refurbished the premises in 1996. The Inn is apparently named after the Morning Star that could be seen from the entrance.

Valleymount House is a stone building that was the village's one and only shop and post office until it closed in 2006.

The village also used to have its own forge which was active until the 1980s.

There is a prehistoric sweathouse in the townland of Annacarney near Valleymount.
