At Seefingan is the 11th highest summit in the Wicklow Mountains, the second highest point in South Dublin after Kippure and the 92nd highest summit in Ireland. It stands at the junction of three ridges, Corrig to the north, Seefin to the southwest and Kippure to the east, and straddles the border between County Wicklow and South Dublin. The headwaters of the River Dodder lie on the eastern slopes of Seefingan, Kippure and Seecawn.
