Tibradden Mountain

Tibradden Mountain (Irish: Sliabh Thigh Bródáin, meaning 'mountain of the house of Bródáin') is a mountain in County Dublin in the Republic of Ireland. Other former names for the mountain include "Garrycastle" and "Kilmainham Begg" (a reference to Kilmainham Priory which once owned the lands around the mountain). It is 467 metres (1,532 feet) high and is the 561st-highest mountain in Ireland. It forms part of the group of hills in the Dublin Mountains which comprises Two Rock, Three Rock, Kilmashogue and Tibradden Mountains. The views from the summit encompass Dublin to the north, Two Rock to the east and the Wicklow Mountains to the south and west.

The geological composition is mainly granite and the southern slopes are strewn with granite boulders. The summit area is a habitat for heather, furze, gorse and bilberry as well as Sika deer, foxes and badgers. The forestry plantation on the slopes – known as the Pine Forest – contains Scots pine, Japanese larch, European larch, Sitka spruce, oak and beech. The mountain is also a site of archaeological interest with a prehistoric burial site close to the summit.
